Looking for fun, educational activities to do at home? This list of easy chemistry experiments and science activities will allow you to perform experiments with materials you likely already have in your kitchen cupboards .

You don't need esoteric chemicals and a lab to have a good time with chemistry. Your average fourth-grader can make slime , and it doesn't get any less fun when you're older, so this is a good at-home experiment for kids and adults alike.

Borax Snowflake

Anne Helmenstine

Making a sparkly borax snowflake is a crystal-growing project that's safe and easy enough for kids. You can make shapes other than snowflakes, and you can color the crystals. If you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free. If they develop a white precipitant, lightly rinse them but don't dissolve too much crystal.

Mentos and Diet Soda Fountain

This is a backyard activity best accompanied  by a garden hose . The Mentos fountain  is more spectacular than a baking soda volcano . If you make the volcano and find the eruption to be disappointing, substitute these ingredients.

Penny Chemistry

You can clean pennies, coat them with verdigris, and plate them with copper. This project demonstrates several chemical processes , yet the materials are easy to find and the science is safe enough for kids.

Invisible Ink

Invisible inks either react with another chemical to become visible or else weaken the structure of the paper so the message appears if you hold it over a heat source. But we're not talking about fire here; the heat of a normal light bulb is all that's required to darken the lettering. This baking soda recipe is nice because if you don't want to use a light bulb to reveal the message, you can just swab the paper with grape juice instead.

Colored Fire

Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce smoke that is any better or worse for you than normal wood smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar result. This is suitable for a home fire or campfire, plus most chemicals are found around the house (even of non-chemists).

Seven-Layer Density Column

Make a  density column with many liquid layers . Heavier liquids sink to the bottom, while lighter (less dense) liquids float on top. This is an easy, fun, colorful science project that illustrates the concepts of density and miscibility.

Homemade Ice Cream in a Plastic Bag

Science experiments can taste good! Whether you're learning about  freezing point depression or not, the ice cream is a delicious result either way. This cooking chemistry project potentially uses no dishes, so cleanup can be very easy.

Hot Ice (Sodium Acetate)

Got vinegar and  baking soda ? If so, you can make " hot ice ," or sodium  acetate , and then cause it to instantly crystallize from a liquid into "ice." The reaction generates heat, so the ice is hot. It happens so quickly that you can form crystal towers as you pour the liquid into a dish.

Burning Money

The " burning money trick " is a  magic trick   using chemistry . You can set a bill on fire, yet it won't burn. Are you brave enough to try it? All you need is a real bill.

Coffee Filter Chromatography

Exploring separation chemistry with coffee filter chromatography is a snap. A coffee filter works well, though if you don't drink coffee you can substitute a paper towel. You can also devise a project comparing the separation you get using different brands of paper towels. Leaves from outdoors can provide pigments. Frozen spinach is another good choice.

Baking Soda and Vinegar Foam Fight

The foam fight is a natural extension of the baking soda volcano . This easy chemistry experiment is a lot of fun and a little messy, but quick enough to clean up as long as you don't add food coloring to the foam.

8 Easy Chemistry Experiments At Home (Get a Great Reaction!)

If you want to have some fun with chemistry at home, there are three main ways to go about it. You can buy a chemistry set, subscribe to a subscription box, or find some instructions and use household items. However you go about it, chemistry is a great way to get kids excited about chemistry and science in general.

Chemistry Sets and Subscription Boxes

Before we dive into easy experiments, you can do with things you’ll probably have at home. I just wanted to talk a little bit about your other options.

Chemistry sets can be an excellent investment. They come with equipment that you can reuse over and over. It’s a lot cheaper than having to replace your drinking glasses and measuring jugs because the kids keep using them for chemistry experiments! They also come with instructions on a range of experiments that you can try. If you’ve done a few of the experiments below and are looking for something more, a chemistry set can be a really good option. There are ones aimed at young kids all the way up to teenagers .

Another great option to consider is subscription boxes. These are great for extending learning and keeping kids entertained and engaged for a more extended period. There are loads of great options to choose from. But, when it comes to chemistry, you really can’t go wrong with MEL Science . They have two subscription levels, so you can get a big box or a small one each month. Because everything is in the box, it really takes all the planning and hunting for ingredients out of the equation.

Experiments Using Household Items

If you don’t have a science kit on hand and are looking for something quick and easy to try at home, then these are the experiments you should try. Most of these use items that you will probably have at home, although a few might require you to get a little creative or grab the odd thing the next time you go to the shops.

Chromatography

Chromatography is a technique used in chemistry. It lets you find out what’s inside chemicals. In this version from Fizzics Education, you’ll see what colors are mixed up inside felt tip pens. It’s a straightforward experiment to carry out. All you need is some paper towels, felt tips, and a glass of water.

This is a simple version of this experiment, but there are some easy ways to make it more interesting or scientific. One way to extend this experiment is to try the same technique but using your favorite sweets’ colorings.

For instance, sweets like M&Ms, Skittles, and Smarties all have food coloring on their outside. You can get a sample of this coloring by sitting the candy in a small amount of water. Then you use the colored water in the same way as the felt tip pens.

To add a bit of rigor and math to the experiment, you need a pencil and a ruler. Instead of drawing a line of felt tip, you draw a line with a pencil. Then put a spot of the felt tip on the pencil line. When you take the paper out, you mark a second pencil line to show how high the water went.

By measuring the distance, each of the colors went and the distance the water went, you can calculate something called the retention factor. The retention factor will be unique for different dyes. To find the retention factor, you take the distance your sample travels and divide it by the length the solvent (water in this case) traveled. You can use this number to see if the same dye is used in different pens.

Pop Rockets

This is one of my favorite chemistry experiments for kids. It does get a little messy, so make sure you have some cloths on hand. Alternatively, you can do it outside to make it a little easier to clean up. Steve Spangler Science has some great instructions to follow.

In their version, they use an old film canister. But these can be a bit hard to get hold of these days since everything is digital. Some good alternatives that work well include empty glue stick containers. It’s also worth keeping your eye out for any food containers with push-on lids, as these can work well. There are always a lot of good options around Halloween, Christmas, and Easter – the snack size containers tend to be pretty good options.

The reason I love this experiment is that it’s a lot of fun. There’s the excitement of the pop and watching the canister fly. But, there are also a lot of opportunities to turn this into a real investigation. You can try changing the volumes of liquid or the type of liquid. You can find the best mix to make the biggest noise, the loudest pop, or the perfect mix to make it pop in precisely 8 seconds.

Make Oobleck Dance!

Oobleck is the name that’s been given to an awesome type of slime that you can make at home. If it sounds like something out of Dr. Suess, that’s because it is. This slime is just a mix of cornstarch and water, so it’s pretty easy to make. These instructions from Housing A Forest are pretty good.

What’s cool about Oobleck is that it’s a Non-Newtonian solid. That means that it behaves a little differently than you might expect. For instance, when you try to stir it quickly, it gets hard and almost solid. If you run your fingers through it slowly, it flows like runny syrup.

Now just playing with this stuff is fun, but if you have a speaker to hand, you can do something even cooler. In the guide from Housing A Forest, they suggest using a subwoofer and a cookie sheet. The speaker’s vibrations make the Oobleck bounce around and switch from a solid to a liquid to the beat of the music.

If you have an old speaker that you don’t mind breaking, you can wrap the speaker in saran wrap and put the Oobleck straight onto that. It works a lot better, but if you don’t cover the speaker correctly, it can break.

Make Rubber Eggs

Eggs are an excellent ingredient for science experiments. This experiment from 3P Learning lets you turn a hardboiled egg into a bouncy rubber one. To do this, all you need to do is soak it in vinegar for a day or so. This will dissolve the calcium carbonate of the eggshell. When it’s done, you’ll be able to rub off the tough outer shell.

Without the shell, you’ll be left with the membrane that lines the shell. This membrane helps hold the egg together. This membrane is strong enough to drop the egg onto a surface from a reasonable height, and it will bounce back without falling apart.

The harder your egg is, the less it will bounce. If you want a mix between bounciness and minimal potential for mess, then you’ll want to aim for a soft boiled egg. But, if you don’t mind the mess, try a raw egg. You remove the shell in the same way. When it comes off, you get a peek inside the raw egg. Because it’s raw, it’s squishy and bounces better. Of course, if you drop it from high enough, it will break. When you do this, you’ll find the stretchy membrane, which is pretty cool to feel.

Lemony Eruption

I’m sure you’ve all done the classic volcano eruption with baking soda and vinegar. This is a twist on that experiment. It takes advantage of the fact that lemons are already full of natural citric acid. Here are some great instructions from Babble Dabble Do. They have some handy tips on how to make the most out of each lemon. The great thing about this version is that your room will smell lovely and lemony for the rest of the day.

If you want to extend this, you try investigating which other fruits this would work with. You could explore a whole citric family of volcanoes.

Concoct Some Invisible Ink

Write Secret Messages With Invisible Ink! by Science Buddies

Making invisible ink is really easy. There is some fun chemistry behind how it works. As a bonus, once your kids get the hang of it, they’ll have loads of fun sending coded messages. It’s a great way to keep them entertained.

This great recipe from Thoughtco can be revealed using two different methods. If you have a safe and controllable heat source, you can hold the paper up to that. Ironing the paper works as well, although that’s best left to adults. Otherwise, you can use purple grape juice to reveal the message. If you paint over the page with grape juice, the message will show up in a different color.

If sending secret messages isn’t appealing to your kids, you could challenge them to create something artistic with this technique. The only limit is their imagination.

If you’ve done any chemistry experiments for kids, then you probably know that an acid + baking soda makes for an awesome fizzy experiment. I’ve seen this used in many different ways, but this version from STEAM powered family is one of the best.

In this experiment/activity, you encase small dinosaur toys in a paste made of baking soda and water. By adding food coloring, you can create multicolored eggs. You can even hide glitter inside for an added surprise. When made, you freeze the eggs for about an hour, so they are set hard.

To hatch the eggs, you give your kids syringes and a cup of vinegar. They can then apply the vinegar wherever they want to discover what’s hiding inside the eggs. Just remember to place the eggs in an easy to wash container with reasonably high sides.

Fireworks Alternative

I love fireworks, but I feel guilty about enjoying them because they are an environmental disaster. So, whenever bonfire night rolls around, I always set this up to have some fun and color in our home without having to damage the environment. It’s not quite as good as fireworks, but it’s pretty cool never-the-less.

All you need is:

• Oil – any sort will do. Cheap vegetable oil is just fine
• Food coloring (The liquid kind, not gel)
• Droppers (medicine syringes work well too)
• A clear, tall jar – a mason jat is perfect

To get the magic going, all you need to do is fill your jar ¾ full with warm water. Then add a good layer of oil on top. About an inch deep is plenty. Then you use your dropper to drip food coloring into the jar.

At first, the food coloring will sit at the interface between the oil and water. Then all of a sudden, it will drop through, leaving a trail of color behind it in the water. It looks impressive if you do lots of drops of different colors and then sit back and watch as they drop through the liquids.

Eventually, your water will turn a muddy, muddle color. But, this is such an easy experiment that you can wash out your jar and try again.

Just a little not to say that if you can’t get hold of a dropper or syringe then you can just drip the food coloring from the bottle. As long as you only put in small amounts at a time it does still work.

If you want to extend the fun, keep the oil and some of the colored water when you pour out the container. You want to have more oil than water this time, so I suggest moving them to a second smaller bottle. Then if you add an Alka-Seltzer tablet, you’ve got a homemade lava lamp. To get the best effect, stand your lava lamp bottle on top of a light.

Frequently Asked Questions

What are the most useful household ingredients for chemistry experiments.

When it comes to chemistry experiments, having the right ingredients makes all the difference. If you like explosions, then you’ll probably want to have a good supply of baking soda and vinegar on hand. Other common ingredients include ice, food coloring, citric acid, cornflour, and borax.

If you’re planning on doing lots of experiments, you might want to have a clear measuring jug and a few clear bowls of glasses that you don’t mind sacrificing.

Absolutely! There is loads of chemistry behind making food taste great. If you like a perfectly browned steak, then you’re a fan of the Maillard reaction. If you like sweets and desserts, then you’re benefiting from the careful balance of ingredients and use of temperature needed to create the textures and flavor you love.

There is a whole field of science called food science, which is a specific field of chemistry. A great introduction to this field is to experiment with the ratio of ingredients in a simple recipe. You’ll learn what effect the different ingredients have on the outcome. Alternatively, you could make a sourdough starter.

What is the easiest science project?

All of the experiments on this list are pretty easy to try. The chromatography experiment is probably the one that has the most common equipment and is pretty hard to mess up. The fireworks alternative is also an easy experiment that looks great.

Sandy is an experienced STEM educator, having spent a decade teaching Physics. She also loves to volunteer at local STEM fairs to show kids, especially girls, how awesome it is. She is so passionate about science that one science degree wasn’t enough and she decided to complete a second part-time, while working.

37 Cool Science Experiments for Kids to Do at Home

General Education

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

• Teaches Kids About: Zoology
• Difficulty Level: Medium
• Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

• Materials Needed
• Shadow box or other box with multiple compartments
• Hot glue gun with glue
• Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

#2: DIY Lava Lamp

• Teaches Kids About: Chemical reactions
• Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

• Vegetable oil
• Food coloring
• Antacid tablets

#3: Magnetic Slime

• Teaches Kids About: Magnets
• Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

• Liquid starch
• Adhesive glue
• Iron oxide powder
• Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

• Teaches Kids About: Chemical reactions, earth science
• Difficulty Level: Easy-medium
• Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

• Baking soda
• Dishwashing detergent
• Large mason jar or soda bottle
• Playdough or aluminum foil to make the "volcano"
• Additional items to place around the volcano (optional)
• Food coloring (optional)

#5: Tornado in a Jar

• Teaches Kids About: Weather
• Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

• Glitter (optional)

#6: Colored Celery Experiment

• Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

• Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

• Glass jar with a lid
• Boiling water
• Aerosol hairspray

#8: Edible Rock Candy

• Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

• Large saucepan
• Clothespins
• String or small skewers
• Candy flavoring (optional)

#9: Water Xylophone

• Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

• Wooden sticks/skewers

#10: Blood Model in a Jar

• Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

• Empty jar or bottle
• Red cinnamon candies
• Marshmallows or dry white lima beans
• White sprinkles

#11: Potato Battery

• Teaches Kids About: Electricity
• Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

• Fresh potato
• Galvanized nail
• Copper coin

#12: Homemade Pulley

• Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

• Clothesline
• 2 clothesline pulleys

#13: Light Refraction

• Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

• Sticky note
• Transparent water bottle

#14: Nature Journaling

• Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

• Blank journal or notebook
• Pens/pencils/crayons/markers
• Tape or glue for adding items to the journal

#15: DIY Solar Oven

• Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

• Aluminum foil
• Knife or box cutter
• Permanent marker
• Plastic cling wrap
• Black construction paper

#16: Animal Blubber Simulation

• Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

• Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

• Tissue paper
• Thick paper
• Glue stick/glue

#18: Edible Double Helix

• Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

• 2 pieces of licorice
• 12 toothpicks
• Small marshmallows in 4 colors (9 of each color)
• 5 paperclips

#19: Leak-Proof Bag

• Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

• Zip-lock bags
• Objects with sharp ends (pencils, bamboo skewers, etc.)

#20: How Do Leaves Breathe?

• Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

• Large bowl (preferably glass)
• Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

• Popsicle sticks
• Rubber bands
• Plastic spoons
• Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

• Clean 16-oz soda bottle
• 6% solution of hydrogen peroxide
• 1 packet of dry yeast
• Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

• Penguin image (included in link)
• Spray bottle
• Blue food coloring (optional)

#24: Rock Weathering Experiment

• Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

• Plastic wrap

#25: Saltwater Density

• Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

• Four clear glasses
• Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

• Toaster oven

#27: Inertia Wagon Experiment

• Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

• Stack of books

#28: Dinosaur Tracks

• Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

• Used coffee grounds
• Wooden spoon
• Rolling pin

#29: Sidewalk Constellations

• Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

• Sidewalk chalk
• Small stones
• Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

• Plastic bottle
• Rubber band

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

• Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

• Clay or gumdrops (in four colors)
• Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

• Straws (paper work best)
• Twine or yarn

#34: Solar Energy Experiment

• Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

• 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

• Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

• Pencil with eraser
• Aluminum tray or pie tin
• Styrofoam tray

#36: Tie-Dyed Milk

• Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

• Shallow dish
• Milk (high-fat works best)

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

• Safety pins
• 2 glass jars

Summary: Cool Science Experiments for Kids

Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child's specific interest or what they're currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

Easy Chemistry Experiments for Kids

October 19, 2021 By Emma Vanstone 1 Comment

When I think back to my own childhood and school days, I don’t remember any chemistry experiments until secondary school, which is a shame because there are so many wonderfully visual easy chemistry experiments for kids that can be done at home or in school with young children.

I’ve put together a collection of my favourite examples, do let us know if you try any.

  Please remember young children should be supervised at all times.

Chemistry Experiments for Kids in the Kitchen

Exploding sandwich bags .

I did struggle a little when we tried this as the reaction happens so fast, but  Steve Spangler has a nifty method where he traps the vinegar in a second smaller bag, which you then have to burst to get the reaction started.

Inspiration laboratories add a twist by adding some colour and making  firework pictures at the same time.

Blow Up a Balloon

This is a super simple demonstration or experiment that has never failed me, and all you need is a container with a small neck, a balloon and either an alka seltzer or an effervescent vitamin tablet. The alka seltzer or vitamin tablet reacts with water to release bubbles of carbon dioxide filling the jar and then blowing up the balloon.

Blow up a balloon with alka seltzer

Find out how to blow up a balloon with lemon juice and baking soda.

Colourful Milk

Make a lovely, colourful display using milk, food colouring and vinegar.

Oil, Food Colouring and Water Exploration Table

My oil, water and food colouring exploration table is brilliant for even very young children. For older children, try a more structured approach, they could measure the amount of vinegar and baking soda needed to make the reaction spill over the top of the beaker or try dropping tiny amounts of coloured water into the oil.

Density Rainbow Jar

Learn about the tricky concept of density and make a beautiful demonstration density jar .

Simple Density Jar

If you don’t want to make as many layers as we have, why not try this smaller version and try to find an object to float on each layer?

Lemon Volcanoes

This lemon volcano from Babble Dabble Do is a great alternative to the traditional volcano and is handy as the lemon already contains acid.

Clean coins

Did you know you can clean coins with vinegar ?

Colourful Chemistry Experiments

Make your own ph indicator.

Test the pH of vinegar and baking soda with a red cabbage indicator . What do you think might happen if you blow into the indicator?

Dissolving Skittles

Watching the colour dissolve from skittles or M & Ms dissolve into water is a lovely, quick, visual activity.

Chemistry Experiments for Kids Outside

Giant bubbles.

Who doesn’t love a giant bubble ? Red Ted Art makes bubble making look easy in this great video. Remember, the mixture gets better the longer you leave it, so allow plenty of time.

Make a Square Bubble

All you need to make a square bubble is a square frame. If you don’t have plastic pieces to use, pipe cleaners also work well.

Coke and Mento Reaction

The infamous coke and mento reaction is super easy and very impressive to watch. Try comparing the size of the geyser using diet and full sugar cola or using different types of fizzy drinks.

Can you design something which allows the mentos to drop in as soon as you remove the lid?

Elephants Toothpaste

Fun at Home with Kids makes elephants toothpaste   look super simple, but do be careful with the hydrogen peroxide and take appropriate precautions.

Film Canister Rockets

Film canister rockets are easy, inexpensive and great fun. All you need is a film canister, an effervescent vitamin tablet and some water. Experiment with different amounts of water and tablets to find the most explosive combination.

Make a Volcano

Find out how to make a volcano erupt with sand, snow or papier mache. A baking soda volcano is a brilliant classic chemistry experiment every kid should try at least once!

Chemistry Separation Methods

Bicycle centrifuge.

Did you know you can use bike wheels as a very basic centrifuge ?

Stone and Gravel Filter

Learn about filters by making a filter with stones , gravel and sand.

Filter Paper Chromatography

Take on the role of a detective with some fun filter paper chromatography .

Can you think of any more amazing chemistry experiments for kids?

50 Chemistry Projects That Will Amaze Kids!

February 26, 2019 by Ana Dziengel 5 Comments

Chemistry projects feel like magic , do they not? If you think about some of your favorite science projects, the ones you love to try with your kids or the ones that amazed YOU as a kid, more likely than not most of them involved chemistry.

Now I know a lot of us associate chemistry with lab coats, beakers and specialty ingredients but the reality is there are so many chemistry projects you can do using very simple, easy to find ingredients, often found in your own pantry. And since these types of simple chemistry projects use relatively safe ingredients, they are perfect to try with younger kids, ie. preschool and elementary aged children! In fact I think it’s so important for young kids to have a positive association with chemistry from a young age that fosters a love of this branch of science.

When most children are finally exposed to chemistry in school, it is at the high school level where the subject turns complex quickly; hopefully giving kids a chance to have fun at young age mixing up concoctions and watching chemical reactions will help carry their interest through the more complicated days of study ahead.

This post is a GIANT compilation of  chemistry projects that would be great for the science fair, classroom demos, or at home science with your kids.

Before we get started let’s talk a little bit about what chemistry is and for parents I also included a section covering How to Do Chemistry Projects at Home. If you are a classroom teacher you can skip this section and head right to the projects here.

What is chemistry?

Chemistry is the branch of science that studies matter (anything that has mass and takes up space) and its properties, and how different substances (especially molecules and their atoms) interact, combine, and change to form new substances.

Here are some important definitions to know when working on chemistry projects:

• Element A substance that cannot be separated into any further substances. There are 120 known elements.
• Atom The smallest particle of an element
• Molecule Groups of atoms held together by a chemical bond.
• Ion  An atom or molecule that has an electric charge

While most people think of chemistry purely in terms of chemical reactions, chemistry also covers the study of the states of matter as well as the density of substances.

The five branches of chemistry are:

• Analytical chemistry
• Physical chemistry
• Organic chemistry
• Inorganic chemistry
• Biochemistry

Read more about what each branch covers here.

How to Do Chemistry Projects at Home

Many chemistry projects can be done at home using simple materials and are a great way to foster a love of science in kids! I wholeheartedly believe that a wow factor in a project engages and inspires kids to learn more. If you want to try chemistry projects at home here are some suggestions and precautions:

Safety First

Even though most of the projects in this list use safe, easy to find materials they should be used with safety precautions and under adult supervision. Why? Sometimes the chemical reaction that ensues can irritate the skin or eye, can be harmful if swallowed, or is just plain sticky or  messy and adults should be on hand to supervise use . Also be advised that there are a few projects on this list that do use materials that are unsafe for kids to handle. These projects are meant to be demonstrations only and are labeled  accordingly.

• Use household items for chemistry   The classic chemistry project that never fails to impress is the reaction of baking soda (sodium bicarbonate) and vinegar (look for a number of variations on this classic in our Acids and Bases section) but there are lots of other great ingredients for chemistry to find in your kitchen including sugar, salt, yeast, lemons, dish soap, milk, Kool- Aid, cabbage, gelatin, and food coloring to name a few…before you order any materials online, try some projects with pantry essentials.
• Safety Goggles
• Large plastic beakers
• Prepare for mess Since a lot of chemistry involves reactions and the ensuing mess, be sure to choose a place in your home that you can easily clean up and where you won’t worry about getting dirty. A patio, breakfast area, or the garage are great choices.
• Generous work area Be sure to have a large table available so everyone has plenty of room to work and/or view projects without bumping into each other.
• Access to Water Clean up is always easier with water at the ready! Choose a location near a hose or shop sink.

Managing Messes

• Hose it down  Depending on the project I suggest doing super messy chemical reactions outside. That way spills can be hosed down easily.
• Painter’s Tarp & Trays  If you cannot go outside a large plastic painter’s tarp is a great way to contain spills and mess. I also highly recommend doing projects on trays or cookie sheets. The raised edges help contain bubbly brews and are easy to dump out and wash.
• Dump station Have a bucket nearby to act as dump station for liquid reactions. Bring it around a table and dump at each station.
• Think about disposal Vinegar kills grass! Slime bits clogs drains! Be sure to consider where you can dump out the liquids safely.

Chemistry Projects for Kids

The following chemistry projects for kids are sorted by topic: Chemical Reactions, Acids and Bases, Carbon Reactions, Chromatography, Colloids & Solutions, Polymers,  and Crystals.

Please note that many if these projects could fit in two or more categories in this post as they demonstrate various scientific and chemical processes. I only classified them once on this list.

Chemistry Projects with Chemical Reactions 

What is a chemical reaction.

Chemical reactions occur when the chemical bonds in a substance are either destroyed or created. In other words the bonds in a molecule are broken during a chemical reaction and the atoms rearranged to create new molecules. Interestingly enough the number of original atoms does not change during the reaction, they are simply reconfigured.

An easy way to explain chemical reactions to kids is to use this analogy: Atoms are like letters, molecules are like words. Chemistry is like taking apart words and rearranging the letters to form a new word.

Read more about chemical reactions here.

Chemical Reactions Projects:

1. milk painting, 2. citrus battery, 3. elephant toothpaste.

<span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>

4. Density Lava Lamps

To make a density lava lamp fill a plastic bottle with the following liquids: Clear corn syrup, water with a few drops of food coloring, and  layer of vegetable oil. Be sure to leave a space at the top of the bottle. Wait until the liquids settle then add in a tablet of extra strength alka seltzer. Watch as the alka seltzer and water react and bubble up through the oil layer.   To see this in a  step by step video check out this video (Pssst this is one of our students!!!)

5. Plastic Milk   and Curds & Whey Experiment

6 . color mixing.

Pour water into three clear plastic cups, then add blue, red, and yellow food coloring to each. Have an additional cup full of uncolored water available as well. Give your child an empty ice cube tray and pipettes and let them create different colors by mixing different ratios of two different primary colors in each ice cube compartment. The secondary colors are new colors created from two primary colors. This is a simple visual of how chemical reactions work.

7. Chemistry Clock

8. blow balloons with yeast and sugar, 9. shiny pennies.

• Collect dirty tarnished pennies.
• Pour different acidic liquids into shallow containers. Try vinegar, salsa, lemon & lime juice.
• Add a teaspoon of salt to each container and stir to combine.
• Place a handful of pennies in each container and soak for 5 minutes.
• Remove them from the solution and rinse in soapy water. Let dry on separate paper towels.
• Compare the results! Which ones are shiniest? Which are dull? Did any turn green?

Acids are corrosive and sour tasting. Liquids such as vinegar, lemon juice, and tomato juice are acids. Pennies are made from copper which tarnishes (turns dark) when exposed to oxygen over time. Placing the copper pennies in an acid will clean the copper oxide off them and make them shiny again.

Learn about Acids and Bases

Most liquids are either an acid or a base. Liquids with lots of hydrogen ions in them are considered acids. Liquids with many hydroxide ions are bases. Scientists use a scale called the ph scale to measure how acidic or basic a liquid is. The more hydrogen ions in a liquid the more acidic it is and ranks low on the ph scale. The more hydroxide ions in a liquid the more basic it is and ranks high on the ph scale.  You can see what that looks like here.

When acids and bases are mixed chemical reactions occur and the solution becomes neutralized.

Acid and Bases Projects:

1. baking soda & vinegar volcano, 2. lemon volcano, 3. the colorful cabbage juice science experiment   and acid base experiment with cabbage, 4. dancing rice, 5. green eggs & ham, 6. bubbly citric acid brew , 7. baking soda vs baking powder science experiment, 8. exploding bags, 9. rainbow rubber eggs , 10. surprise eggs  , 11. rainbow wizard’s brew, chemistry projects with fire (carbon reactions).

Carbon is the most important element for life. Chemicals that contain carbon are called organic compounds.  Carbon has two main forms: The first is in the hard form of diamonds and graphite, and the second is the impure form found in charcoal, coal and soot.

SAFTEY WARNING: Carbon reactions are always fascinating to watch however the presence of fire means that these experiments must be supervised by adults at all times!  

Carbon Reactions Projects:

1. smoking fingers, 2. fire snake, 3. silver egg, 4. invisible ink, chromatography.

Chromatography is the process of separating mixtures. We usually think of it in terms of color hence the prefix -chroma, however in chemistry is means simply a method of separating mixtures by letting them slowly move past each other. It applies to both liquids and gasses.  This is wonderful in-depth explanation of chromatography.

Chromatography Projects:

1. chromatography  .

In this project you will separate the color black into other colors. Fold a coffee filter in half. Fold in half two more times until you have a triangular shape. Color the tip of the coffee filter with washable black marker. Get a good coat of ink on the filter. Add a small amount of water to a plastic cup. Place the black tip of the coffee filter in the cup Wait and observe. Come back to the filter after an hour or two and see what happens to the ink. As the coffee filter absorbs water through capillary action, the black ink moves through the filter and is separated by the water into other colors. You should see blue, green and even red as the water separates the ink.

2. Chromatography Flowers

3. chromatography art, 4. chromatography bags, colloids and solutions/solubility.

Colloids and Solutions are two types of homogenous mixtures.

• Colloids are mixtures in which a small particles of a substance are suspended throughout another substance but not chemically bonded. They are stable though and do not separate. Examples of colloids are gelatin, butter, mayonnaise, fog and smoke.
• Solutions are mixtures in which the particles of one substance are completely dissolved in another substance. The solute is the substance being dissolved and the solvent is the substance doing the dissolving. An example of a solution is saltwater.

Colloid Projects:

1. colloid examples, 2.  oobleck  , 3. make butter , 4. gelatin streaking, solutions/solubility projects:, 5. ice sculptures , 6. ice cream in a bag.

7. Skittles Science

8. magical water blossoms  <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_selres_start”></span>, 9. diffusion art, 10. paint solubility  , 11. bleeding blossoms  .

A polymer is a substance made up of a long chain of molecules.  Polymers are typically flexible materials like plastic or gum.

The classic polymer kids LOVE to make is slime! Glue is already a polymer but when combined with sodium tetraborate (borax ) the protein molecules of the glue and the borate ions crosslink, making it harder for the molecules to move and forming the gooey, sticky, substance we know as slime.

Other polymers you are probably familiar with are plastic bags, balloons, instant snow, and even the powdery substance found in diapers that expands when wet.

Polymer Projects:

1. best basic slime  .

Bonus: Get the Science Behind Slime printable here

2. Heat Sensitive Slime

3. diy bouncy balls, 4. magic plastic bag experiment, 5. instant terrariums, 6. how to make paper, 7. skewer through balloon , 8. dry erase figure   and dry erase drawings, 9. recycled plastic flowers.

Crystals are a type of material that is formed by patterns of repeating molecules. There are four types of chemical bonds in crystals and therefore four categories of crystals. These are: Covalent, Molecular, Metallic, and Ionic Crystals. You can grow crystals by mixing up a super saturated solution (usually with a type of salt and water) and letting it settle over time so crystals will form. Check out the various types of easy to grow crystal below and go here to read more about the science of crystals .

Crystals Projects:

1. classic borax crystals , 2. overnight crystal garden, 3. egg geodes, 4. crystal wind catchers, 5. crystal landscapes, 6. candy geodes , 7. salt crystals, conclusion & more.

Alright you guys, do you feel like you have some good project ideas for exploring chemistry with kids? Many of these will make greats science fair projects. Be sure to start with them as a topic then start asking questions, form a hypotheses, and do some experiments.

Now I have to admit that I really fell in love with chemistry projects as an adult. Working with kids in camp, after school, and with my own kids at home I’ve had the chance to try fun chemistry projects and discovered that I love watching chemical reactions AND the reactions on the faces of kids and bystanders during demonstration or project!

If you have kids who fall in love with this branch of science please do check out the incredible book series Elements , Molecules , and Reactions by Theodore Gray (see the series in our Amazon science ideas list here ) The books are stunning, informative, easy to understand and, wait for it…funny!

13 Awesome Chemical Reaction Experiments You Can Do At Home

Categories Activities & Ideas

Kids love to play mad scientist. And what better way to get kids excited about chemistry than with a few awesome chemical reaction experiments you can do at home?

Chemistry is an important branch of science that plays a big role in our everyday lives – so it’s definitely a subject children should learn about.

Luckily, chemistry is like performing magic – it’s fun to learn and do!

So, with that said, here are some awesome chemical experiments that can be done at home, all just as fun as they are educational.

Just remember: For health and safety, just make sure to supervise your child while doing the following experiments. If you’re a teacher, conduct these experiments in class or have the child’s parents supervise them at home.

1. Mentos & Diet Soda Chemical Volcano Eruption

Mixing mentos and diet soda is a classic experiment that produces a large chemical reaction that’s ideal for showing kids what chemistry is capable of. It’s safe and non-toxic, but the experiment can get messy, so it’s best to do it outdoors!

For this chemical reaction experiment, all you’ll need are a two-liter bottle of diet soda, a test tube or sheet of paper, an index card, and Mentos candies. You can use normal soda instead of diet soda, as well as M&Ms or Skittles instead of Mentos.

2. Baking Soda And Vinegar Balloon Experiment

If you have never seen a self-inflating balloon, this awesome chemical reaction experiment is sure to amaze the kids. The best thing is that baking soda and vinegar are common household items, so this experiment is easy enough to do at home.

All it involves is mixing baking soda and vinegar in a bottle and placing a balloon on the open end. The chemical reaction between baking soda and vinegar will release carbon dioxide gas that will inflate the balloon.

3. Green Flames

Copper sulfate is another item that can be easily found in most homes, but what’s special about it is that it can turn flames green. This chemical reaction experiment is best done in a fireplace or with a small controlled flame.

This is another awesome experiment that’s simple to do. Simply sprinkle copper sulfate onto a flame to see the color turn blue. You can also use alcohol or an alcohol-based fuel before lighting to achieve a brighter green color.

4. Fireproof Balloon

If you have more balloons left over from the baking soda and vinegar balloon experiment shown above, creating a fireproof balloon is another awesome chemical reaction experiment that’s easy to do and sure to impress.

For this experiment, all you need are two balloons, 50 milliliters of water, a syringe, and a candle or lighter. Simply blow two balloons up, one with 50ml of water added using the syringe. Hold each balloon over a candle to see which one bursts!

5. Foaming Volcano At Home Experiment

The foaming volcano experiment is similar to the baking soda and vinegar experiment except that it’s less explosive and involves different items. It uses baking soda, liquid soap, red food coloring, and acetic acid to create a foaming chemical reaction.

All it involves is using plasticine to create a volcano, then filling the inside with baking soda, a few drops of food coloring, and liquid soap. The last step is adding the acetic acid to watch the volcano erupt. Perform the experiment outside or in a tray to avoid mess!

6. Ice Cream In A Bag

Teach children that cooking also involves chemistry! This ice cream in a bag chemical reaction experiment is a great way to teach kids about freezing point depression, creating a tasty treat that they can also eat afterward.

The main items you’ll need for this experiment include zipper-top bags, ice, sodium chloride as table salt or rock salt, and ingredients for the ice cream, which are sugar, milk, whipping cream, and vanilla flavoring.

7. Elephant Toothpaste

This elephant toothpaste experiment is another simple chemical reaction that you can do at home using common household items. All you’ll need are an empty bottle (plastic or glass), 6% hydrogen peroxide, dry yeast, dish soap, food coloring, and warm water.

Similar to the foaming volcano, this elephant toothpaste experiment creates a chemical reaction that will see the bottle overflow with a foamy liquid. To make it extra fun, conduct the experiment with different food coloring!

8. Smoke Without Fire Experiment

“There’s no smoke without fire” unless you’re a chemist! This fun smoke-without-fire experiment demonstrates an awesome chemical reaction that creates smoke using a combination of concentrated hydrochloric acid and ammonia.

You will need some science equipment to perform this experiment, which includes three flasks connected by gas pipes. The chemical reaction produces a slow release of white smoke with, you guessed it, no fire or sparks.

9. Liquid Layer Density Tower

Density towers, or density columns, are a great way to show and explain the density levels of different liquids. You can use honey, corn syrup or pancake syrup, liquid dishwashing soap, water (with food coloring if desired), vegetable oil, rubbing alcohol, and lamp oil.

When you have a jar or container, the key is to put the heavier liquids in first, then pour the next liquids in using the side of the container. Even if you don’t get it right the first time, it’s a fun experiment that also creates a colorful display item!

If you and the kids don’t mind getting messy, this slime experiment is a fun chemical reaction that will create a thick, stretchy slime that becomes firmer and less sticky the more it’s played with. You can also add food coloring to create different colors of slime!

For this chemical reaction experiment, you’ll need borax powder, water, glue, and food coloring if you want to add color to the slime. You’ll also need a bowl, jar or measuring cup, and teaspoon for mixing.

11. Ignite A Candle With A Battery

Show your class that it’s possible to light a candle without matches or lighters with this awesome battery experiment! All it requires is an AA battery, chewing gum wrapper, cotton wool, scissors, and a candle.

You might not know this, but the chewing gum wrapper is coated with a layer of aluminum. As a good electrical conductor, the wrapper will generate an electric current when connected to the battery. The aluminum will heat up and light the cotton, which will ignite the candle.

12. DIY Lava Lamp

Lava lamps are awesome, so why not make a DIY one at home using an awesome chemical reaction? Although this DIY lava lamp won’t shine as brightly as a regular lava lamp, it’s still a fun experiment that will teach the kids about density.

The end result is a colorful liquid (use any kind of food coloring you like) with floating bubbles that can make a great bedroom ornament. It’s quick and simple, too, requiring just 30 minutes to create overall.

13. Homemade Science Christmas Ornament

Perfect for the holidays, this homemade science Christmas ornament experiment will get the kids to create glowing crystal icicles that can be hung outside or on the Christmas tree. It’s simple as well, only requiring borax powder, pipe cleaners, and string or twine.

To perform this chemical reaction experiment, you’ll need to add boiling hot water to a glass jar with borax. Twist the pipe cleaner around a pencil or pen to create a winding shape, then lower the pipe cleaner into the mixture with string. Leave until crystals start to form!

So there you have it: a list of awesome chemical experiments you can do at home to teach kids about the fascinating world of chemistry. These experiments are fun, educational, and sure to amaze kids of all ages!

Don’t forget: For health and safety reasons, just make sure to supervise your child while doing the above experiments or, if you’re a teacher, conduct the experiments in class or have the child’s parents supervise them at home.

45 Easy Science Experiments for Kids

Hello, STEM! These simple DIY activities can be done at home or in school.

We've been independently researching and testing products for over 120 years. If you buy through our links, we may earn a commission. Learn more about our review process.

Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.

None of this is magic. It's all science that you can do at home, most likely with ingredients you already have in your house. So, next time you need a boredom-busting indoor activity on a rainy day or a DIY project to get their minds humming, try one of these best at-home science experiments for kids , which cover topics like cover magnetism, surface tension, astronomy, chemistry, physics and more.

First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)

These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.

Floating Fish

Here's another one that deals with solubility and density.

• Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
• Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
• Tilt the dish slightly from side to side. What happens? Jot it down.

The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)

The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!

This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.

• Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
• Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
• Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
• Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
• Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
• After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
• Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
• Write down your observations in your science notebook.

The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.

Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.

Grow an Avocado Tree

For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone

No for an experiment in sound!

• Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
• Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
• What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
• Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.

Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.

When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.

"Elephant Toothpaste"

Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Paper Bridge

Get the engineering back into STEM with this activity, which challenges kids to create a paper bridge that's strong enough to hold as many pennies as possible. How can they manipulate the paper to make it sturdier? (Hint: Fold it!)

See the paper bridge tutorial at KidsActivities.com »

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Coin Inertia

Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation

What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Chromatography Flowers

Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking

You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

Professor Egghead's Lesson about Light

A Lesson in : Light

Learn all about the sun and what it gives humans (think energy and warmth!) You'll also do an experiment to learn about different kinds of light, even ultraviolet rays. Get the video from Professor Egghead here.  

Messiness factor: 1 sponge 

Cup Amplifier

A lesson in: Sound

Slide a mobile phone into this low-tech amplifier and the result will be music to your ears. The audio is deeper, richer, and louder, thanks to the science of sound waves and the natural amplification created by the cone-shaped cups. If the two cups look a bit like the attentive ears of a cat or fox, that’s no coincidence. Animal ears use the same science, but in reverse: they help creatures hear by gathering sound waves and directing them into the ear. For engineers, that’s a design worth copying.

Customize your amplifier to fit any size phone!

Tabs cut all around the hold make it easy to glue the cardboard tube in place.

Cut a slot with a flap to support your phone.

What’s Going On The Cup Amplifier focuses and projects sound waves, in the same way that a cheerleader’s megaphone (or even just your cupped hands) amplifies your voice. Once sound waves are created, they want to spread out in all directions. The amplifier directs them from your phone’s speakers into the cardboard cups, where, instead of scattering, they are gathered and channeled in one direction—out the openings.

Skittles Science

A Lesson in: Stratification

A great way to get rid of extra candy, this easy science experiment for kids uses Skittles and whatever liquids you want to use. The idea is, the candy is made of ingredients that dissolve, so kids get a chance to guess which liquid will make the Skittles dissolve the fastest. Get more info over at Little Bins for Little Hands . 

Find Out How Many Water Drops Fit on a Coin

A Lesson in: Chemistry

An easy science experiment to do at home is one that helps kids find out what affects the surface tension of water! You'll need basic materials like a penny and a water dropper, and be sure to make a hypothesis before you start. You might be surprised! Get the tutorial from Rookie Parenting . 

Pulley Experiment

A Lesson in: Physics

This simple experiment requires a trip to the hardware store, but putting it all together is a cinch. Once you've completed the system, have your kids pick up different-sized rocks and make a note about how difficult it is. Then, try with the pulley. Is it easier or is it harder? To find out how to make your pulley, and for other questions to ask your kids, head over to Little Bins for Little Hands . 

Make a Volcano Explode

A Lesson in: Chemical reactions

There's a reason why this science experiment is so popular. When the solid baking soda (sodium bicarbonate—a base) mixes with the liquid vinegar (acetic acid—a weak acid), it creates a gas—carbon dioxide! Besides the chemical reaction, kids enjoy making the actual volcano, whether it's out of clay, mud, or foam sheets. Get a great step-by-step tutorial from The Dad’s Book of Awesome Science Experiments by clicking here . 

Messiness Factor: Four sponges

Bake Hygroscopic Cookies

A Lesson in: Hygroscopy. 

This simple science experiment is best when you check in on it the next morning. Bake up a batch of cookies, then place them in an airtight container with a piece of fresh bread. Watch as the cookies stay straight-from-the-oven soft thanks to the moisture of the bread (The sugar in the cookies is hygroscopic, which means it absorbs water molecules out of the bread). The best part? Getting to eat the cookies!

The Juice-Tasting Challenge

A lesson in : Taste buds and olfactory senses.

Tummy’s rumbling–it’s time to eat! Did you know that you “eat” with your nose and eyes as well as your mouth? It’s true. Put your family’s sense of smell and sight to the test with this juice-guessing game.

You’ll Need: Masking tape 4 glasses Pen and paper 4 flavors of juice 4 food colorings

How to: 1. Stack a piece of tape on the bottom of each glass and number them one to four, making sure your partner can’t see the numbers. Pour one type of juice into each glass.

2. Send your partner out of the room. Drip a different food coloring into each juice and stir so your partner can’t recognize the juice by its color alone. Record the number, juice type, and color in each glass on a piece of paper.

3. Call your partner back. Tell her to hold her nose, sip from each glass, and guess the juice If she’s like most people, she’ll be kind of confused–her eyes and tongue give her two conflicting flavor messages.

4. Ask her to unplug her nose, close her eyes, and sniff the juice before drinking it. Her guesses should be on target now. All hail the mighty schnoz!

Experiment with Tie Dye

A lesson in: Chemistry.

Dyes are fiber reactive, so there's a chemical reaction between the dye and the fabric. You can do this experiment with everything from paper to t-shirts. We've got a great list of tie-dye projects here . 

Messiness Factor : Five sponges.

Make a Sundial

View this post on Instagram A post shared by Jennifer Carter (@_thebestkindofchaos_)

Unravel the mysteries of time. Or at least figure out the basics by setting up a sundial outside . Take time each hour to check the sun’s positioning and make note of it so your sidekick can see the bigger picture.

Messiness Factor : One sponge

Dry Ice Bubbles

A lesson in: Gas.

Dry ice is already cool enough on its own, but it takes science to turn them into bubbles. When you add water, it changes the temperature of the dry ice, causing the ice to go from solid to gas. That’s where the fog and bubbles come from! Head to Simply Modern Mom to get the full tutorial. But be careful: Dry ice can cause serious skin burns, so make sure your kids are well-supervised and know not to touch the ice.

Messiness factor: Three sponges.

Invisible Licorice

A lesson in : Light and perspective.

Did the candy melt or disappear? Your sweetums might think it’s magic, but it’s really all about how oil redirects light, causing half the candy to disappear! Click here for the instructions on how to recreate this mind-warping experiment.

Egg in a Bottle

Your whistler has the basics of air pressure down just by using their mouth to blow. And now you can amaze them with this science experiment for kids. There is a little fire play involved (dropping a lit paper into the bottle), but that’s what causes the unbalanced air pressure, which pushes the egg into the bottle. Want to test it out? Head over to Steve Spangler Science for the tutorial.

Invisible Ink

A lesson in: Oxidation.

If your snacker has noticed how their apples have turned brown after being left out for too long, then they’ve seen oxidization in action (loss of electrons and nutrients when in contact with oxygen). Fortunately, lemon juice only oxidizes when in contact with heat. This method works with baking soda and milk too. Click here to find out how to write secret messages with your little spy.

Kid-Safe Lava Lamps

A lesson in: Density and intermolecular polarity.

These sound like big words for our little ones, but there’s an easier way to break it down. Water and oil won’t mix because they’re not the same “weight” or substance (just like clay and LEGOs won’t become one). Now add a drop of food coloring (which is heavier than oil) and a fizzy tablet and watch the air bubbles take coloring with them to the top. Head on over to S. L. Smith’s blog to see how it’s done .

Messiness factor: Two sponges.

A Lesson in: Crystallization.

Be careful: The water only has the power to make the sugar crystals “invisible” when it’s piping hot. After the water cools down and evaporates, the sugar turns back into a solid. And with a little help of your sugar-soaked string, the crystals will find a home to grow upon and become rock candy. Learn how to make your smart sweets with these instructions from the Exploratorium .  

S'more Solar Oven

A lesson in: Solar power.

Harness the power of the sun to make your favorite campfire treat! With just a few common household items you can create an  eco-friendly oven  just for melting marshmallows and chocolate, plus you can teach kids about the power of the sun. Click  here  to learn how.

Homemade Slime

A lesson in: Polymers.

Is it a liquid or solid? The answer is both! This DIY slime—made from glue, borax, and water—is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Check out Explorable’s recipe for mixing the ingredients . Prolong the life of your goo by keeping it in an airtight container in the fridge. And, if you need help with cleanup, check out our guide for how to get slime out of clothes, couches, and hair . 

Make Fizzy Lemonade

Plain old fresh-squeezed lemonade is so last year. Boost the fun quotient and learn a simple science concept simultaneously when you recreate this edible Fizzy Lemonade drink from  Learn With Play at Home . It’s super easy to mix and little sippers report it’s pretty tickly too. A great alternative to the baking soda-vinegar volcano, it shows kids what happens when an acid and base are mixed together. 

Whirlpool in a Bottle

A lesson in: physics, weather science. 

This easy little experiment doesn't take much: just two empty and clear 2-liter bottles, a metal washer, water and duct tape. Food coloring is optional. Fill one bottle with about two-thirds water. Place the washer on the bottle and line up the empty bottle on top of the water-filled one. Wrap the duct tape around the middle securing the two bottles together. Then, turn the bottles upside down. Does the water go straight down or do you see a mini whirlpool (Swirl the top or bottom a bit for a better effect.)? The spinning water is called a vortex, and all tornadoes, hurricanes and typhoons are examples of air vortexes. Since you’re using water, this is an example of a whirlpool. As the water spins faster, it pushes to the outside of the bottle creating a hole in the middle. The air from the bottom of the bottle comes up the middle and the water from the top flows back down through the hole.

Messiness factor : Two sponges.

Salt Crystal Feathers

A lesson in: Evaporation

You’ve probably tried a salt crystal growing kit at some point in your life (5th grade Science Fair perhaps?) but Schooling a Monkey takes the idea to a new level with these Salt Crystal Feathers. This awe-inspiring project is deceptively simple and inexpensive to achieve, and requires just a wee bit of patience to see the results—kids will love checking in on the progress. 

Soda Blasting Experiment

A lesson in: Chemistry, pressure, and release of pressure

This experiment is one you'll definitely want to do outside. Step it up with this Mentos + soda experiment: head to Steve Spangler  for all the need-to-know details on this engaging experiment. 

Messiness factor: Three (very epic) sponges

Melting Rates

A lesson in: Solar science and absorption

Different colors have different heat-absorbing capacities. Black has the greatest heat-absorbing capacity, which results in ice melting quicker than white, which reflects the most light. Learn how to observe and report on which colors affect ice’s melting rates here on Curiodyssey.  Get more sidewalk science ideas here .

Make Elephant Toothpaste

A lesson in:  Chemistry and the exothermic process <<<impress your kids! 

If you’ve ever wondered how elephants keep their tusks clean, we’ve got the answer. They use elephant toothpaste! Find out how to mix your own and figure out the science behind this dynamic exothermic (heat-releasing) reaction from Fun at Home With Kids . Our favorite part? That you get to throw in some sensory playtime after the action’s over.

Messiness factor:  Three sponges. Maybe four. 

Bending Water with a Comb

A lesson in: Electrical currents and static electricity

This  static electricity science experiment couldn't be any easier. In fact, other than a balloon or going down the slide, it might be the easiest way to teach kids about electrical currents. And, you can impress them with your wizarding skills once before you reveal the science behind it. Click here to get the step-by-step. 

Regrow Leftovers

A lesson in : Photosynthesis and plant science.

Insert a little plant science into the mix by re-growing food from scraps. Think onions, potatoes, and lettuce for this one ( psst… green onions are a super easy, fast option). Get the low down on all that recycled goodness at Mrs. Happy Homemaker . Since plants need water and sunlight to grow, exposing scrap roots to that winning combo helps them recharge.

Messiness factor:  Two sponges.

Turning Pennies Green

A lesson in: Chemical reactions.

It happens to the Statue of Liberty and it happens to the change in your pocket! Create your own home lab with just a few household ingredients (this experiment will literally cost you just pennies). It’s also a chemical reaction with very non-toxic ingredients, so it’s safe and fascinating even for young kids. Click over to Buggy and Buddy to get the simple how-to.

Film Canister Rocket

A lesson in: Rocket science.

Like the popular baking soda and vinegar experiments, this film canister rocket literally takes it to the next level by using that creation of gas and energy to jet off into the sky. If your explorer has seen videos of mountain tops getting blown off during a volcanic eruption, this science project is pretty much any space lover’s version. Get the building instructions over at The Science Kiddo .

Disappearing Egg Shell

Can you and the kiddos solve the mysterious case of the disappearing eggshell? Following the simple how-to at Go Science Kids , you’ll learn the step-by-step and talking points about the process along the way. Warning! Although it’s totally non-toxic, toddler-aged kids will be tempted to squeeze the egg at the end so make sure it’s a supervised experiment. Visit Go Science Kids to get cracking!

Fishing for Ice

A lesson in: Freezing/temperature.

Children living in snow-covered cities might witness their neighbors salting the driveway. Well, while that is definitely not for fun, this experiment is. Salt lowers the freezing point of ice so it melts, but it won’t be able to freeze unless it’s cold enough. See how The Science Kiddo made a clever game with this knowledge.

A lesson in: How clouds hold water.

Let your imagineers pretend shaving cream is a cloud that holds colorful raindrops. As they squeeze more and more food coloring, their “cloud” will soon release the excess below—just like how real clouds get too heavy and let the rain loose on a gloomy day. Learn how to re-create this weather experiment here .

Dyed Plants

A lesson in: Capillary action.

Find out how plants “drink” water with some food coloring . Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments  over  here .

Dancing Oobleck

A lesson in: Sound waves.

The word “oobleck” comes from a Dr. Seuss story where a young boy must rescue his kingdom from a sticky substance. But the neat part of this experiment is how oobleck reacts to vibrations. Put the oobleck over a subwoofer (on top of a cookie sheet!) and watch it dance to different frequencies. Your dancer will see how sound isn’t just about volume! Check out more of this awesome experiment from Tammy of Housing a Forest .

Messiness factor: Five sponges.

Homemade Lightning

A lesson in: Static electricity. (Or weather science.)

Lightning is essentially electrons moving uber fast between the sky and the earth—and with a few simple materials, you can use homemade static electricity (the reason behind your hair sticking up when you rub a balloon or go through a tunnel slide super fast) for DIY lightning. Figure out how to recreate a family-friendly version of this spark by visiting the activity blog Learn Play Imagine .

Make a Bug Vacuum

A Lesson in: Entomology

Scientists capture bugs for study using a mouth-powered vacuum, called an aspirator or a pooter. Kids can make their own version from a mason jar, then use it to gather ants (or other small insects) and observe them in action.

What you'll need: Pint-size mason jar with a two-piece lid Milk or juice carton Hole punch 2 bendy straws Tape Gauze pad

How to:  1. Open the milk carton along the seams and flatten it out. Use the inner lid of the mason jar as a template to trace a circle on the carton. Cut out the circle and punch two holes in the center about an inch apart.

2. Carefully slide the short ends of the bendy straws into the holes. Tape a piece of gauze pad around the end of one straw to prevent any bugs from getting sucked up.

3 Set the lid on the jar and fasten it in place with the ring.

4. To use your pooter, place the tip of the straw without the gauze near a bug. Put your mouth on the straw with the gauze, and gently suck in. The bug should travel up the straw and land unharmed at the bottom of the jar.

Take It Further Capture some ants in your bug vacuum, then use a magnifying glass to observe these remarkable insects up close. Open the jar and feed them a few drops of sugary water or corn syrup, or try giving them some birdseed. Ants live in colonies headed by a queen ant, and they can’t last long on their own. When you are done observing them, release your ants where you found them. (Note: Some ants bite, so be careful handling them.)

Tell Me More Ants were the Earth’s first farmers. For millions of years, certain species have been creating underground gardens where they grow their favorite fungus for food. They tend to their crops, bringing them water and even weeding out other fungi they don’t want.

A Smell Challenge

A Lesson in: Olfactory senses.

Teach kids the importance of smell with this activity that asks them to use only their noses to identify objects. Can they sniff out the fish oil over the garlic cloves? The lemon juice over the orange oil? Homeschooling blogger Ana has the instructions at Babble Dabble Do .

Is This Soluble?

A Lesson in: Mixtures 

Teaching children chemistry can become a fun, at-home activity as a weekend afternoon project or as part of their remote learning curriculum. One of the best experiments you can do is the mixing activity. With this exercise, children will learn the difference between soluble and insoluble substances. Do not worry! You can do it with ingredients you already have in your kitchen!

Ingredients

• Oil (cooking oil, vegetable oil, olive oil, etc.)
• Food Coloring
• Transparent containers with a lid or transparent cups with a spoon to mix

Before you begin the activity, ask the children what each ingredient is—whether it is a solid, liquid, or gas—and what they think will happen when you begin mixing them. This guarantees a hands-on experiment that will allow the children to feel they are in control.

• Mix the water and the sand. Children will notice there is a separation between both ingredients and that layers have formed, so it is an insoluble reaction.
• Mix the water and the food coloring. Children will see them combine—the water turning into that color—and know it is a soluble reaction.
• Mix the water and the table salt. The salt will disappear in the water, making it another soluble reaction.
• Mix the water and the oil. This time, a clear layer will be formed, showing another insoluble reaction.

After these mixing activities, you can further this experiment by letting the children find other ingredients to mix with water and have them determine if that substance is soluble or insoluble. The main goal is to show them different reactions and layers.

For a clear example of this experiment, check out this video .

We can all agree that science is awesome. And you can bring that awesomeness into your very own home with these 20 safe DIY experiments you can do right now with ordinary household items.

1. Make Objects Seemingly Disappear Refraction is when light changes direction and speed as it passes from one object to another. Only visible objects reflect light. When two materials with similar reflective properties come into contact, light will pass through both materials at the same speed, rendering the other material invisible. Check out this video from BritLab  on how to turn glass invisible using vegetable oil and pyrex glass.

2. Freeze Water Instantly When purified water is cooled to just below freezing point, a quick nudge or an icecube placed in it is all it takes for the water to instantly freeze. You can finally have the power of Frozone from The Incredibles on a very small scale! Check out the video on this "cool" experiment. 

3. Create Oobleck And Make It Dance To The Music Named after a sticky substance in a children’s book by Dr Seuss , Oobleck is a non-Newtonian fluid, which means it can behave as both a solid and a liquid. And when placed on a sound source, the vibrations causes the mixture to gloopily dance. Check out these instructions from Housing A Forest  on how to make this groovy fluid funk out in every way.

4. Create Your Own Hybrid Rocket Engine With a combination of a solid fuel source and a liquid oxidizer, hybrid rocket engines can propel themselves. And on a small scale, you can create your own hybrid rocket engine, using pasta, mouthwash and yeast. Sadly, it won’t propel much, but who said rocket science ain’t easy? Check out this video from NightHawkInLight on how to make this mini engine.

5. Create "Magic Mud" Another non-Newtonian fluid here, this time from the humble potato. "Magic Mud" is actually starch found in potatoes. It’ll remain hard when handled but leave it alone and it turns into a liquid. Make your own “Magic Mud” with this video.

6. Command The Skies And Create A Cloud In A Bottle Not quite a storm in a teacup, but it is a cloud in a bottle.

8 fun chemistry experiments for kids

Arousing a child’s interest in science is not as complicated as it feels. Chemical experiments often do not require any special devices or reagents, while they are very visual and effective.

If you allow your child to experiment independently, you can be sure that he or she will remember this process for a long time. However, you should remember the following point: the child needs to be explained that what he or she saw is not a miracle but the result of chemical reaction. Among other things, adults should still observe the actions of children for safety purposes.

To impress a child, you can add ordinary vinegar to baking soda. Pour more soda (about two tablespoons) into a small bowl and put vinegar on it. You can pour directly from the bottle.

Soda and acetic acid will react with the release of gas, and therefore the contents will begin to boil and foam right in front of your eyes. When conducting this chemical reaction, you should be careful not to lean close to the reagents.

You may improve the experiment and prepare a small theatrical performance for the child. Make a plasticine cone with a hole (volcano) and fix it on the bottom of the vessel. During the reaction of acetic acid and soda, a miracle will happen: the foam will begin to splash out like a real volcano!

To make the slime, you will need PVA glue, starch, three cups, a mixing container, food dye of the desired color.

We dilute the starch in water and measure out the same amount of glue, liquid starch, and water. It turned out three glasses with different substances. Pour water into a container and add PVA and mix thoroughly. Now, gradually add the dye to the mixture. After each serving, mix thoroughly. And so on, until you choose the color to your taste. You can even mix several dyes to get interesting shades.

The classic slime has a light green color. After the color is selected, add the liquid starch. It is important not to waste time and thoroughly stir the mixture until smooth until it thickens.

3. Edible sugar glass

Edible sugar glass is one of the variants of the comic performance. With its help, it’s easy to play with friends. With a certain skill, you can make quite plausible-looking objects from edible glass, for example, plates. If sugar is poured into pre-prepared molds, then you can make some toys, for example, soldiers, jewelry items, and much more. In general, the range of applications of sugar glass is limited almost only by your imagination. Molten and then frozen sugar is difficult to distinguish from the glass at first glance because both substances have a crystalline structure.

To make edible glass, you need to take a cup of sugar. We will also demand a frying pan, a baking sheet, a parchment for pastries, and a little butter. The parchment is greased with oil and located in a cold place. Meanwhile, warm up the sugar on low heat, mixing continually. After a while, the sugar will thicken and turn into a viscous mass.

If you add a little food coloring at this stage, then the edible glass will come out colored. Now it’s time to take the parchment out of the refrigerator, spread it out on a baking sheet, and carefully pour the melted sugar on it. After the mass has cooled, it will harden and turn into a glass-like substance. This is the edible sugar glass.

4. The shining liquid

There is the following myth. The shining liquid is still drinking water. Many people are seriously convinced that this type of liquid can be drunk. You don’t need to follow the example of those who will try to prove this information on their own. While the reaction is going on, compounds of chemical elements can significantly predetermine the deterioration of your health status.

In addition to the above, the shining liquid can be made with the help of a particular drink. We will need Mountain Dew lemonade. Also, you will need to take the bicarb, peroxide, which can be easily acquired in absolutely any drugstore. Thus, you should keep some of the drinks in the vessel. Then append sodium hydroxide to the drinking on the tip of a teaspoonful and add three teaspoons with peroxide. The bottle is closed and shaken well. Of course, there are no guarantees and no certainty that the right reaction will occur.

However, you should pay attention that there are ways to make a shining liquid. Using this option, the probability of obtaining the sought result will increase. However, if the fluid doesn’t illuminate, you should think about how correct the ingredients you used.

This method of producing a shining liquid is made on the basis of luminol.

For the recipe, you need a few grams of luminol, one hundred milliliters of water, three grams of copper sulfate, eighty milliliters of peroxide, ten milliliters of soda. You need to add peroxide to our liquid and three grams of copper sulfate. Finally, you should put soda in it. You should not apply the plates from which you eat.

5. Malachite egg

The following experiment is not super complicated. You will need calcium carbonate and copper sulfate. The result should be quite interesting: an egg with malachite color. The experience is quite simple but requires patience. The final result of the experiment you will be able to see only in a month, but you will like it!

It is worth paying attention to the fact that the experiment does not require any special reagents. Our experiment will require an ordinary egg, a glass jar, clay, copper vitriol (dry), gauntlets, and, finally, water.

To begin with, we should remove everything that is inside the egg itself. To perform this action, you will need to make two gaps on contrary parts. Now we put a small piece of clay inside the egg to increase the weight. Clay is not required for the chemical reaction itself.

Append 0.5 liters of water, then append a tablespoon of copper and mix it carefully and continually. The next step is to diligently put the eggshell in the can. That’s it! For today, the experience is over. At this moment, you should expect our long-awaited but awesome outcome!

However, do not worry. Some actions in the chemical reaction can already be observed before the end of the term. At first, we will see that gas bubbles will start to be produced from the eggshell. After a week, the eggshell will gradually change its color shade. After a period of one month, we will finally be able to enjoy the view of the egg with an amazing malachite hue!

6. Luminous flower

Now we will share three ways to make a real glowing flower. We will need a blacklight lamp, aka wood lamp, aka ultraviolet light lamp. These are sold in almost all electrical goods stores and costs as usual energy-saving. The bases of the blacklight lamps are available for any lamps.

We will need a text highlighter. Make sure that the trace of it glows under the blacklight lamp. Cut the marker pen and pull out the fibers with the ink. Squeeze the ink into a container with a small amount of water. Put the bloom there. Wait for a while until your chosen floret absorbs the fluorescent dye. When the ink permeates the flower, its petals will glow under the blacklight.

Spill a tonic, such as Schweppes, into a glass. Cut off the tip of the bloom stem and drop it into a glass. Wait a few hours until the quinine tonic penetrates the flower petals. Turn on the blacklight and enjoy your flower.

Tips for creating a glowing bloom:

• It is better to use flowers with white or slightly colored petals because they are colored much better.
• Use fresh, wholesome flowers. Blooms that are almost dead will not consume water and will not shine.
• Some flowers repaint better than the others. Cloves and chamomiles repaint better than roses.

7. Growing crystals

To grow crystals at home, make a saturated solution of salt or other reagents. Hang a small crystal in it, and it will gradually begin to grow grains from all sides.

Growing crystals is an interesting and informative activity for a child. It is quite safe, and it is easy to perform even for elementary school students under the supervision of their parents. The experience does not require a laboratory. It can be carried out at home.

Good raw material:

• Salt. The most affordable way is to make a crystal from table salt. You can take the sea one.
• Sugar. As a bonus, you will get a sweet tea, which will especially please the children.
• Double salts. This is an inexpensive material and is freely sold in pharmacies, as it is a means to stop bleeding.
• Copper vitriol. It forms stones of expressive blue color. It can be purchased in chemical and agricultural stores. It looks like a deep blue powder. Greenish and with lumpy lumps, it is better not to take it-this shows that it is damp and has too many impurities. Growing a crystal from such a material would be difficult.
• Sol Mora. It is a white or light blue powder. Pale green crystals grow out of it. It is sold in chemical reagent stores.
• Ammonium nitrate. It produces long and flat colorless crystals. It is sold in a fertilizer store called “ammonium nitrate”.
• Silver nitrate.

Instructions for creating a stone: the principle of crystal formation is the complete dissolution of the reagent in water and its subsequent precipitation. The slower the process is, the more regular the shape of the stone is obtained.

List of things needed for the experiment:

• The substance from which the stone is planned to be made.
• Warm water, preferably distilled, but not necessarily.
• Two glass or plastic containers. Glasses or jars will do if you want to create a large crystal. They should be transparent so that you can monitor the process.
• A spoon for stirring the solution.
• A glass or plastic funnel filled with cotton wool or filter paper.
• A thread or wire for hanging the seed grain. So, we need a copper wire because it can be simply removed. Besides, it has a smooth surface, so the crystals will not randomly grow along its length but will concentrate around the seed.
• Stick for fixing the thread on the container. You can take a pencil. But it is better to use an ice cream stick because it is flat and will not roll down, as can be seen in the photo.
• A circle of paper slightly larger than the neck of the jar.
• Gloves, apron.

When experimenting, take dishes that are not used for eating and cooking unless you’re going to grow a solo crystal (or sugar crystal).

8. Egg in a bottle

Egg in a vial is an experience that is interesting for kids and adults. This is a method to distract kids from modern gadgets and interest them in applied sciences.

For this test, you will need a glass vessel, a large egg, matches, paper.

Explanation : it is necessary to take a glass vessel. Other materials are absolutely not appropriate. The egg should be large: selected or 1 grade.

The process of experimenting : before putting the egg in the vessel, it must be cooked, cooled, and peeled from the shell. Crumple the paper, put it in a bottle, and set it on fire. When the paper burns to 50%, put an egg on the neck. After 2-3 seconds, the egg will be drawn into the bottle. Demonstration of experience always causes surprise and lively interest in children.

Explaining the experience to children

Parents do not have to puzzle over how to explain the experience with an egg in a bottle to their child — it’s all about physics. When heated, the air inside the vessel expands. As soon as the egg is on the neck, the air inside stops getting in. At this point, the paper finishes burning, and the air starts to cool. At the same time, it shrinks, which helps to push the egg into the bottle — it just tightens inside. A boiled egg is easier to put in a bottle than a raw egg. But you can also do such a project with children. Besides, you will need vinegar and a deep bowl.

Egg trick recipe

The egg (raw, in the shell) is placed in a bowl and filled with vinegar. You should wait 15 hours, carefully take it out and rinse it. Now you need to take a bottle, set fire to the paper inside it, put an egg on the neck. The egg is sucked into the bottle in a second! The fact is that the object soaked in vinegar is easily compressed (becomes plastic) and therefore easily falls inside the vessel. To get the egg inside the bottle, you will need a regular plastic bag: the bag is pushed inside so that the open part remains outside. The bag needs to be inflated. Then the vessel should be abruptly turned over, and the package should be pulled out with a quick movement. The egg will instantly pop out.

A simple experiment demonstrates the physical processes. So, it is easier for the child to clarify the laws of physics, tell them, and show clearly the secrets of such experiments.

The kids themselves are investigators, demonstrating an acute and astute interest in various research activities and experimenting. The experimenting affects the elaboration of mind, logical representing, creativeness and clearly demonstrates all the connections in nature.

Research provides the child with the opportunity to reply to the questions «how» and «why». The knowledge gained during the experiments is remembered for a long time.

8 Simple Chemistry Experiments That Your Kids Can Do at Home

Chemistry is a fascinating subject. And what better way to learn than through science experiments?

Here are 8 hands-on science experiments for kids over the school holiday. These experiments are great for older children, or with assistance from mum or dad. They can be done at home with ingredients you already have on hand.

So pick an experiment, and grab your lab coats to get started!

1. Cabbage chemistry

2. lolly fountain, 3. bath bombs, 5. rubber egg, 6. crystals, 8. snot slime, cabbage chemistry.

Follow these instructions to learn about acids and bases using red cabbage.

Safety: This activity requires the use of a knife, poisonous chemicals and hot water. Ask an adult to assist you. Always follow the safety advice on the products you are using.

You will need

• fresh red cabbage
• sharp knife
• cutting board
• hot tap water
• 7 clear plastic disposable cups
• 7 plastic spoons
• large plastic bottle
• strongly acidic, e.g. powdered toilet cleaner
• acidic, e.g. vinegar, lemon juice, white wine, lemonade or citric acid
• weakly acidic, e.g. cream of tartar
• neutral, e.g. pure water, shampoo or baby shampoo
• slightly basic, e.g. bicarbonate soda
• basic, e.g. milk of magnesia, washing soda or floor cleaner
• strongly basic, e.g. dishwasher liquid or powder
• Using a sharp knife and cutting board, finely slice three or four red cabbage leaves.
• Place the cabbage leaves in the plastic bottle, half fill the bottle with hot water and screw the lid on tightly.
• Shake the bottle for a few minutes until the water becomes a deep purple colour. Leave the solution to cool.
• Strain the solution and add sufficient water to the solution to make about 1 L.
• In each of the cups, place a small amount of one of the above household substances in the following order: strongly acidic; acidic; slightly acidic; neutral; slightly basic; basic and strongly basic.
• Now half fill each cup with the red cabbage water and stir the solution. If arranged in order, the jars should display a spectrum of colours from cherry red (strongly acidic), pink-red (acidic), lilac (slightly acidic), purple (neutral), blue (slightly basic), green (basic) and yellow (strongly basic).

What’s happening

The things we eat and drink are all acidic, and the things we use for cleaning are basic. This is because basic substances taste unpleasant, but a cleaning agent usually needs to be basic to remove dirt and grease.

Substances that are acidic or basic make the eyes sting, so baby shampoo is made neutral.

Acids are a very common group of chemical compounds, many of which occur naturally. Acids can be strong or weak.

Citric acid, which occurs naturally in lemons, is a weak acid. Hydrochloric acid (used for soldering) and sulfuric acid (battery acid) are very strong acids.

Bases (often called alkalis) are another group of chemical compounds that have different chemical properties from acids. When bases and acids are added together, they will neutralise each other’s properties.

We describe whether things are acidic, basic or neutral by using a scale called the pH scale. The pH scale ranges from zero to 14. A substance with a pH of:

• 0 is a very strong acid
• 3 – 5 is a weak acid
• 7 is neutral
• 8 – 9 is a weak base
• 13 – 14 is a very strong base.

Pure water has a pH of seven and is regarded as neutral.

Acids and bases can be detected by a group of chemical compounds called acid-base indicators. One of the first known naturally occurring indicators was a type of lichen called litmus. (Lichens are plant-like growths that are often found on rocks and tree bark.) Litmus turns red in the presence of an acid or blue with a base.

Most indicators used today to detect acids and bases are man-made. However, many plant pigments, such as the red cabbage you used, contain chemicals that act as acid-base indicators.

Looking for more science resources?

There are over 120 science e-books in the reading eggs library to read and explore., lolly/candy fountain.

Learn more about gases by creating a soft drink fountain using lollies/sweets. What a sweet way to find out more about chemistry!

• Roll of lollies/sweets (mint lollies/sweets work well)
• 2 L bottle of soft drink
• Piece of paper or a tube for the lollies/sweets
• Outdoor area

Do this activity in an outdoor area.

• Open the bottle of soft drink and place the bottle on the ground so it will not tip over.
• Roll up the paper into a cylinder that’s just wide enough for the lollies to slide through.
• Put your finger over the bottom of the roll and ask your friend to put the lollies into the paper tube.
• Hold the tube of lollies just above the bottle and remove your finger so all the lollies drop straight in. You need to drop all the lollies into the bottle at the same time.
• As soon as you have done that, move away from the bottle as quickly as possible.
• Diet soft drink works just as well and is less sticky to clean up as it contains no sugar.
• Orange soft drink doesn’t always work. Neither does Solo as it is light on fizz.
• Experiment with different types of lollies – Kool Mints were used in this activity. Try Mentos or other sugar coated lollies.
• Experiment with the soft drink at room temperature or from the fridge.

What’s happening?

Soft drink is bubbly because carbon dioxide gas has been forced into the bottle under pressure.

Until you open the bottle, the gas mostly stays dissolved in the liquid and cannot expand to form bubbles, which the gas will do when not under pressure.

If you shake the bottle and then open it, the gas escapes with a whoosh, taking some of the soft drink along with it. Adding anything to a soft drink enables more bubbles to form and escape.

Try stirring soft drink with a spoon – it gets less fizzy.

The lollies provide lots of surface area very quickly, which means the bubbles of gas form very rapidly in huge numbers.

You need non-smooth surfaces to enable the gas to form.

Both sand and sugar have the same effect when dropped in soft drink.

When you look at a glass of soft drink, there are normally just a few streams of bubbles coming off specific points on the glass where the surface is uneven.

Sometimes you see a stream of bubbles coming from the middle and if you look carefully you can often see a piece of dust with bubbles coming off its end.

The place where the bubbles start to form is called the centre of nucleation.

As the lolly dissolves, it forms hundreds of nucleation points which are tiny pits on the surface of the lolly where more carbon dioxide bubbles can form.

When all this gas is released, it thrusts the entire contents of the bottle skyward, in an incredible soft drink blast.

Make your own bath bombs

Follow these instructions to make your own bath bombs and learn about science while having fun in the bath!

• food colouring/coloring
• flower petals or body glitter
• sweet almond oil
• scented oil such as lavender oil
• 10 tablespoons of bicarbonate of soda
• 3 tablespoons of citric acid
• 2 large mixing bowls
• 1 large muffin tray
• 1 small glass jar
• rubber gloves
• Grease the sides and bases of a large muffin tray with a small amount of almond oil.
• Place the citric acid and bicarbonate of soda into a large bowl. Mix the ingredients together well, to form the base mixture.
• Scoop out about half a cup of this mixture and put it in into another bowl. This will make about one or two bath bombs (depending on the size of the holes in your muffin tray). You could also use old plastic containers or anything that will hold a shape.
• Add the flower petals or body glitter to the base mixture.
• In the small glass jar, mix together 6 drops of your scented oil, 5 teaspoons of sweet almond oil and about 10 drops of food colouring.
• Gradually pour the oil mixture into the half cup of the base mixture. While wearing rubber gloves, quickly mix it all together. The mixture is ready when it stays together in your hands without crumbling too much.
• Spoon the mixture into the muffin tray. Press it down firmly.
• You can use the rest of the mixture with other types of scented oil or food colouring to make more bath bombs.
• Leave the bombs in the tray to set for a few days.
• Carefully up-end your bath bombs to remove them from the moulds.
• Run a bath, hop in and drop a bomb. Watch it fizzzzzz!

What’s happening?

When the bath bomb dissolves in water, there is a chemical reaction between the citric acid and the sodium bicarbonate. The result is called sodium citrate. During the reaction, carbon dioxide is released. This causes the ‘fizzing’ that you see, similar to that in carbonated water.

The sweet almond oil is released during this reaction. It will form a thin layer on your skin which can help to moisturise/moisturize it. The lavender oil is for fragrance.

Wait, there’s more science experiment books in the Reading Eggs Library!

How to make sherbet.

Follow these instructions to create an acid-base reaction in your mouth!

• icing sugar
• citric acid
• bicarbonate soda
• flavored/flavoured jelly crystals
• dessert spoon
• small mixing bowl
• small snap lock bag.

To make sherbet you will need to:

• add 1 level teaspoon of citric acid crystals to the bowl
• add 1 level teaspoon of bicarbonate soda to the bowl
• now add 3 heaped dessert spoons of icing sugar
• add at least 2 level dessert spoons of jelly crystals (or more to taste)
• place a small amount, about half a teaspoon on your tongue
• after tasting you may need to vary the ingredients. If it is too bitter add more sugar, if there isn’t enough fizz you may need to add either bicarbonate soda or citric acid. Make sure you add only in small amounts, remember you can always add more but it is very hard to remove some.

You have just created an acid-base reaction in your mouth. When you combine an acid (in this activity the citric acid) and an alkaline (the bicarbonate soda) with saliva they mix together to create a gas in the form of lots of tiny bubbles.

This is called an acid-based reaction and it’s what gives sherbet its fizz. You are actually feeling the sensation of carbon dioxide bubbles on your tongue. These are the same bubbles that are in fizzy drinks.

The icing sugar is needed to add sweetness as the citric acid and bicarbonate soda are quite sour. Citric acid is one of the acids found in lemons, oranges and limes. That is why they are called ‘citric fruit’.

The other acid in lemons and other citric fruit is called ascorbic acid. This is commonly known as vitamin C. The jelly crystals simply add flavour.

Follow these instructions to make an egg bounce while learning about chemical reactions.

• hard-boiled egg, with shell on
• glass of vinegar.

To make your eggs bounce you will need to:

• Put the egg into the vinegar – you should see bubbles start to form on the egg.
• Leave the egg undisturbed for at least a day. You should see some wonderful scum form.
• Take the egg out of the vinegar and rinse it with water. The shell will rub off.
• Give the egg a poke with your finger and squeeze it gently.

Vinegar, or dilute acetic acid, ‘eats up’ the calcium carbonate in the egg shell, just leaving the inner membrane, or skin, of the egg behind. As the calcium carbonate is responsible for making the shell hard, the vinegar soaked egg feels soft and rubbery.

When calcium carbonate (the egg shell) and acetic acid (the vinegar) combine, a chemical reaction takes place and carbon dioxide gas is released. That’s why you see the bubbles.

The chemical reaction keeps happening for about a day until all of the calcium carbonate in the egg is used up. Calcium carbonate is in eggshells, seashells, limestone, and many other materials.

Let’s have a closer look at the chemical reaction. Calcium carbonate’s formula is CaCO 3 and acetic acid is CH 2 COOH.

So the reaction is: CaCO 3 + CH 2 COOH -> Ca 2+ (in the form of a salt) + H 2 O + 2CO 2 .

The calcium ions (Ca 2+ ) float free in the solution. Ions are atoms or molecules that have an electric charge due to the loss or gain of electrons.

Applications

Limestone is a sedimentary rock that is largely made of calcium carbonate. It is ordinarily white, but may be coloured by impurities; iron oxide making it brown, yellow, or red and carbon making it blue, black, or grey. The texture varies from coarse to fine.

Most limestones are formed over thousands of years from the skeletons of marine invertebrates. Among the important varieties of limestone are marl, chalk, oolite, travertine, dolomite, and marble.

Acid rain causes reactions like the ones in this activity. One kind of acid rain can come from air pollution caused by burning fuels that have sulfur atoms, which when burnt produce sulphur dioxide gas.

When the sulfur dioxide mixes in with rain, it turns to weak sulfuric acid. When the acid rain hits the limestone it slowly makes it fall apart, like the egg shell did. People use limestone in buildings and statues.

This is why over time, buildings and statues are being damaged by acid rain.

If you collect small rock samples and drop them in vinegar, you may see bubbles appear, like they did on the egg. The presence of bubbles indicates that calcium carbonate may be present in the sample.

Calcium carbonate reacts with acids to produce carbon dioxide gas, which we observe as bubbles. This is called the ‘acid test’. The ‘acid test’ is one of many tests that geologists use to determine the identity of a rock sample.

Creating Crystals

• Bicarbonate soda
• 3 eye-droppers
• 3 plastic containers or bowls
• Measuring cup
• 3 small plastic cups
• Label the containers ‘sugar’, ‘salt’ and ‘bi-carb’.
• Pour half a cup of warm water into the container labelled ‘sugar’.
• Add a spoonful of sugar to the water and stir until dissolved. Keep adding sugar until no more will dissolve.
• Repeat Steps 2 and 3, but with the salt instead of sugar.
• Again repeat Steps 2 and 3, but this time with bi-carb soda instead of sugar or salt.
• Label the small plastic cups ‘sugar’, ‘salt’ and ‘bi-carb’.
• Use separate eye-droppers to put a few drops of each container’s solution into the matching cup.
• Place the cups in a warm, sunny place and leave them until the liquid has evaporated. What do you see?

You can try this activity with other crystalline substances as well.

When a solid (or ‘solute’) is dissolved in the water until no more dissolves, the solution is ‘saturated’. The amount of substance that dissolves in water increases with temperature. As the solution cools back down to room temperature, there is now more solute in the water than would normally be the case – the solution is ‘supersaturated’.

As the water evaporates, the solute precipitates out of solution in the form of crystals. This is an example of crystallisation. You will notice that each precipitate forms slightly different crystals: they might be different in size and shape. The size and shape of a crystal depend on a number of factors including chemical formula, temperature and pressure. In general, crystals that form slowly tend to be larger than crystals that form quickly.

• Food colouring
• Small mixing bowl
• Plastic spoon
• Pour some cornflour into a mixing bowl.
• Stir in small amounts of water until the cornflour has become a very thick paste.
• To make the slime the colour of your choice, thoroughly stir about five drops of food colouring into the mixture.
• Stir your slime REALLY slowly. This shouldn’t be hard to do.
• Stir your slime REALLY fast. This should be almost impossible.
• Now punch your slime REALLY hard and fast. It should feel like you’re punching a solid.

You can keep your cornflour and water mixture covered in a fridge for several days. If the cornflour settles, you need to stir it to make it work well again.

Anything that flows is called a fluid. This means that both gases and liquids are fluids.

Fluids like water which flow easily are said to have low viscosity, whereas fluids like cold honey which do not flow so easily are said to have a high viscosity.

Cornflour slime is a special type of fluid that doesn’t follow the usual rules of fluid behaviour. When a pressure is applied to slime, its viscosity increases and the cornflour slime becomes thicker.

At a certain point, slime actually seems to lose its flow and behave like a solid. Cornflour slime is an example of a shear-thickening fluid.

The opposite happens in shear-thinning fluids; they get runnier when you stir them or shake them up. For example, when toothpaste is sitting on a toothbrush it is pretty thick, so you can turn the toothbrush upside down and the toothpaste doesn’t fall off.

But if it was that thick when you tried to squeeze it out of the tube, there is no way you could manage it. Fortunately, toothpaste gets runnier when you are squeezing it out of the tube. Other shear-thinning fluids include:

• ballpoint pen ink
• nail polish

Although there are lots of shear-thinning and shear-thickening fluids, nobody has a really good idea why they behave the way they do.

The interactions between atoms in the fluids are so complicated that even the world’s most powerful supercomputers can not model what is happening. This can be a real problem for people who design machinery that involves shear-thinning fluids, because it makes it hard to be sure if they will work.

• 1 tablespoon of unflavoured gelatine (from supermarkets)
• ½ cup golden syrup or glucose
• 1 tablespoon of salt
• Heat-proof bowl
• Place the gelatine and salt in your bowl.
• Add ½ cup of syrup.
• Add ½ cup of hot water. Now is the time to add food colouring if you want icky green or yellow coloured snot.
• Mix every thing together and cool in a fridge for 30 minutes.
• Run a fork through the snotty mixture to see what it looks like. Your mucus will get thicker and thicker as it cools, if it is too thick, you can add more water.

You have just made a realistic model of your very own snot. Mucus is composed of water, epithelial (surface) cells, dead leukocytes (white blood cells), mucins (large proteins), and inorganic salts. Your home made mucus contains water, salt and proteins (gelatine is animal protein, usually made from beef or pig skin and hooves), almost like real mucus.

The gelatine dissolves in hot water making a thick solution, but is insoluble (won’t dissolve) in cold water. When cooled, the particles swell to make jelly-like goo.

Mucus has an important role to play in your body. In your nose it traps dust and anything else unwanted in the air. Mucus dries around particles which harden and this means it can take a quick exit out of your body when you blow your nose.

It’s your mucous membrane that makes snot, and this lines the inside of your nose and respiratory system. The outermost cells of this membrane produce the thick mucus fluid.

You may think that mucus is only found in your nose, but did you know that you also find it in your mouth, lungs, stomach and intestines!

When you get a common cold, an infection in your upper respiratory tract, your body produces loads more mucus than normal to carry away waste material. When sick, your mucus can change colour/color to yellow or green because of trapped bacteria, virus particles and white blood cells – the causalities of your body fighting the viral or bacterial infection.

TOP 10 chemical reactions that you can repeat at home

Safe and spectacular experiments

4. Re­lease of gas

Ma­te­ri­als and equip­ment :

sodi­um bi­car­bon­ate (bak­ing soda);

• Fill a glass 1/3 full of wa­ter.
• Add a tea­spoon of bak­ing soda and a lit­tle vine­gar.
• Light a match and gen­tly low­er it into the glass, not touch­ing the mix­ture.

The match goes out.

Sodi­um bi­car­bon­ate (soda) is a com­pound of the fol­low­ing el­e­ments: sodi­um, hy­dro­gen, car­bon, and oxy­gen.

The re­ac­tion be­tween sodi­um bi­car­bon­ate and vine­gar forms un­sta­ble car­bon­ic acid, which im­me­di­ate­ly de­com­pos­es to wa­ter and car­bon diox­ide. The car­bon diox­ide gas ex­tin­guish­es the flame:

NaH­CO₃ + CH₃­COOH → CH₃­COONa + H₂O + CO₂↑

5. De­struc­tive vine­gar

• Put an eggshell in a glass.
• Fill the glass half full of vine­gar. Ex­am­ine the con­tents af­ter 12 hours.

The eggshell dis­solves in the vine­gar.

Vine­gar is an acidic sub­stance. It has the abil­i­ty to break down sev­er­al sub­stances, such as the cal­ci­um car­bon­ate con­tained in the eggshell:

Ca­CO₃ + 2CH₃­COOH → Ca(CH₃­COO)₂ + CO₂↑ + H₂O

9. Dis­solv­ing poly­styrene in ace­tone

small pieces of poly­styrene;

rub­ber gloves.

• Put on the gloves.
• Fill the bowl half full of ace­tone.
• Low­er the small pieces of poly­styrene into the bowl.

The pieces of poly­styrene dis­ap­pear. Just like this:

Poly­styrene is ex­pand­ed sty­ro­foam and pri­mar­i­ly con­sists of air. This is why it dis­solves so re­mark­ably in ace­tone.

10. In­vis­i­ble ink

piece of pa­per;

cot­ton swab.

• Squeeze some lemon juice into a glass, add a few drops of wa­ter, and mix well.
• Dip a cot­ton swab into the so­lu­tion and write on the pa­per with it. Let the pa­per dry.
• Hold over a burn­ing can­dle.

The text ap­pears.

Lemon juice con­tains acid, which dark­ens at high tem­per­a­tures.

DIY Science Experiments: Exploring Science with Everyday Ingredients

Oluwadara Adetula

In this article, share article.

Science is everywhere, and you don’t need to be in a lab to explore it, although you need adults to be present for some! DIY science experiments are easy to set up and offer a fun, hands-on way to learn about scientific concepts right at home. Let’s dive into some easy and exciting experiments you can try.

DIY Science Experiments You Can Do with Everyday Ingredients

1. invisible ink.

Learn about chemical reactions with invisible ink. Mix lemon juice with a small amount of water. Using a cotton swab or brush, write a message on a piece of paper with the lemon juice solution. Let it dry completely. To reveal the message, hold the paper close to a heat source like a light bulb or iron. The heat will cause the lemon juice to oxidise and turn brown, revealing your secret message.

2. Homemade Rain Cloud

Understand how clouds form with this simple experiment. Fill a clear glass jar with hot water, leaving a little space at the top. Place a plate over the jar and put some ice cubes on the plate. As the water vapour rises, it will hit the cold plate and condense into droplets, forming a “cloud.” The droplets will eventually become heavy enough to fall, simulating rain.

3. Simple Air Pressure Experiment

Explore air pressure with this fun trick. Fill a small glass with water and place a piece of cardboard or stiff paper over the top. Hold the cardboard in place and carefully flip the glass upside down. Slowly remove your hand from the cardboard. The cardboard will stay in place, and the water won’t spill out. This happens because the air pressure outside the glass is greater than the pressure inside, holding the cardboard in place.

4. DIY Plant Growth

Study how plants absorb water and nutrients. Fill two small pots with soil. Plant a few seeds (like corn or beans) in each pot. Water one pot with plain water and the other with water mixed with a small amount of salt. Over time, observe and compare the growth of the plants. The salt will affect the plant’s ability to absorb water, showing how important it is for plants to have the right balance of nutrients.

5. Baking Soda and Vinegar Volcano

This classic experiment demonstrates a chemical reaction. Combine 2 tablespoons of baking soda with a few drops of red food colouring (or any other colour) in a small container. Pour in 1/4 cup of vinegar and watch the fizzing eruption. This reaction occurs because baking soda (a base) reacts with vinegar (an acid) to produce carbon dioxide gas.

6. Floating Egg

Explore the concept of density with this simple test. Fill a glass with water and gently place an egg in it. The egg will sink. Next, dissolve 3 to 4 tablespoons of salt in the water, stirring until the salt is completely dissolved. Add more salt if needed until the egg floats. The salt increases the water’s density, making it buoyant enough to support the egg.

Tips for Safe Experimentation

• Always involve an adult for safety.
• Use materials carefully and avoid spills.
• Clean up thoroughly after each experiment.

These DIY science experiments use common ingredients found in the home and offer a fun way to explore scientific concepts. Enjoy learning and experimenting at home!

Where Education Meets Fun!

10 Easy Science Fair Experiments for Kids, Parents and Teachers

Welcome to our collection of 10 easy science fair experiments for kids ! These hands-on activities are perfect for sparking curiosity and making learning fun. Whether you’re a parent, teacher, or young scientist, these experiments—from erupting volcanoes to DIY lava lamps—are designed to be simple, engaging, and educational. With a little help from an adult, you can dive into the world of science and discover how exciting it can be.

1. Erupting Volcano Experiment

Introduction: Welcome to our exciting science fair project—creating your very own erupting volcano! This experiment is perfect for first and second graders to learn about chemical reactions in a fun and spectacular way. You’ll need an adult to help with some steps, so make sure to have a grown-up nearby!

Objective: To observe and understand the chemical reaction between baking soda and vinegar that causes a volcanic eruption.

• 1 small plastic bottle (500 ml)
• Baking soda (60 grams)
• Vinegar (200 ml)
• Dish soap (5 ml)
• Red food coloring (a few drops)
• Modeling clay or playdough (enough to cover the bottle and form a mountain)
• A tray or shallow container (to catch the overflow)
• Measuring spoons and cups
• Safety goggles (optional, for extra fun and safety)

Hypothesis: Predict what will happen when you mix baking soda, vinegar, and a few other ingredients in your model volcano. Do you think it will erupt like a real volcano?

• Place the plastic bottle on the tray. This is your volcano’s “magma chamber.”
• Use the modeling clay or playdough to shape a mountain around the bottle. Leave the top open so you can add your ingredients.
• Get creative with the shape and details of your volcano!
• In a separate cup, mix together 200 ml of vinegar, 5 ml of dish soap, and a few drops of red food coloring to create your “lava.” This will help make the eruption more colorful and bubbly.
• Pour the vinegar mixture into the bottle in your volcano.
• Add 60 grams of baking soda to the bottle and quickly step back to watch your volcano erupt!

Observation: Watch closely what happens when the baking soda meets the vinegar mixture. You should see a foamy and fizzy eruption that looks like lava flowing down the sides of your volcano.

Results: Record what you observed. Was the eruption slow and steady, or quick and explosive? How high did the “lava” flow?

Conclusion: Explain why the reaction happened using simple science. When baking soda (a base) and vinegar (an acid) mix, they create carbon dioxide gas, which builds up pressure until it forces the liquid out in an eruption. This is similar to what happens in a real volcano, where gases build up pressure underground.

Further Experimentation:

Try the experiment again using different amounts of vinegar or baking soda. Does changing the amounts change how your volcano erupts?

This experiment not only teaches you about chemical reactions but also lets you create a mini spectacle at home or at your science fair. Have fun being a young scientist and remember to clean up after your experiment!

2. Floating Egg Experiment

Introduction: Dive into the fascinating world of density with the Floating Egg Experiment! This simple yet intriguing project is perfect for first and second graders to explore how different solutions affect whether an object sinks or floats. This experiment will need a bit of adult help, so make sure you have a grown-up to assist you!

Objective: To understand how the addition of salt to water changes its density and affects the buoyancy of an egg.

• Tap water (about 500 ml)
• Table salt (about 60 grams)
• 1 large clear glass or jar
• Measuring spoons
• Stirring spoon

Hypothesis: Before you begin, think about whether you believe the egg will float in plain water and what might happen when you add salt to the water. Write down your guess.

• Fill the glass or jar with 500 ml of tap water.
• Gently place the raw egg into the glass of plain water and observe what happens. Does it sink or float?
• Remove the egg carefully.
• Add 60 grams of salt to the water. Stir well until the salt is completely dissolved.
• Once the salt is dissolved, gently place the egg back into the saltwater solution. Observe what happens this time.

Observation: Note down what you see. How does the egg behave in plain water compared to the saltwater?

Results: Record your findings. Did the egg float in the saltwater? Was there a difference in how it behaved in the plain water compared to the saltwater?

Conclusion: Explain why the results occurred based on density. In plain water, the egg sinks because its density is higher than that of plain water. When you add salt to the water, it increases the water’s density, making it denser than the egg, which now floats.

You can experiment further by changing the amount of salt added to the water or trying different liquids like sugar water. See how these changes affect the egg’s buoyancy.

This experiment not only teaches you about the principles of density and buoyancy but also shows you how different solutions can change the behavior of objects in water. Have fun experimenting, and remember to ask questions and think about why things happen the way they do!

3. Rainbow Milk Experiment

Introduction: Get ready to create a swirling rainbow with the Rainbow Milk Experiment! This visually stunning project is ideal for young scientists in the first or second grade to explore the effects of soap on milk and food coloring. You’ll need some help from an adult, so be sure to have one nearby!

Objective: To observe how dish soap interacts with the fat in milk, causing movement in the food coloring that creates a rainbow effect.

• A shallow dish or plate
• Whole milk (enough to cover the bottom of the dish)
• Food coloring (various colors)
• Cotton swabs
• A dropper or small spoon

Hypothesis: Think about what you expect to happen when you add dish soap to the milk with food coloring. Do you think the colors will move, mix, or stay still? Write down your guess.

• Pour enough whole milk into the dish to just cover the bottom.
• Carefully add drops of different food coloring to the milk. Place them around the dish but not too close to each other.
• Dip a cotton swab into dish soap, ensuring it’s not dripping but wet with soap.
• Gently touch the soaped swab to the surface of the milk in the center of the dish or near one of the food coloring drops.

Observation: Watch what happens when the soapy cotton swab touches the milk. Look for any movement of the food coloring and how it interacts with the milk.

Results: Record what you see. Describe the movement and mixing of the colors. How did the dish soap affect the behavior of the food coloring in the milk?

Conclusion: Explain the science behind what you saw. The soap breaks the surface tension of the milk and reacts with its fats, creating movement that pushes the food coloring around. This movement shows how substances like soap can change the physical properties of other liquids like milk.

Try the experiment again using different types of milk (like skim or 2%) to see if the fat content affects the reaction. You can also use different detergents or soaps to see if they cause different patterns or movements in the milk.

This experiment is not only a beautiful display of colors but also a great lesson in chemistry and physics, showing how different substances interact in surprising and colorful ways. Enjoy creating your milk art, and don’t forget to clean up when you’re done!

 4. Baking Soda and Vinegar Rocket

Introduction: Blast off into the world of chemical reactions with the Baking Soda and Vinegar Rocket Experiment! This exciting activity is perfect for first and second graders eager to see science in action. You’ll need some adult supervision, so make sure a grown-up is ready to help with the fun!

Objective: To demonstrate the reaction between baking soda and vinegar and observe how this reaction can propel a homemade rocket.

• 1 small plastic film canister with a tight-fitting lid (or any small container with a pop-on lid that seals well)
• Baking soda (5 grams)
• Vinegar (30 ml)
• Tissue paper
• Safety goggles (to protect your eyes)
• An open space for launching your rocket (like a backyard or park)

Hypothesis: Predict what will happen when baking soda and vinegar mix inside your rocket canister. Think about how it might affect the canister and what the reaction will be like. Write down your prediction.

• Go outside or to a well-ventilated area where you can safely launch the rocket.
• Wrap the 5 grams of baking soda tightly in a small piece of tissue paper. This packet will help delay the reaction, giving you time to close the lid.
• Pour 30 ml of vinegar into the film canister.
• Quickly drop the baking soda packet into the canister with vinegar.
• Snap the lid on tightly and quickly place the canister on the ground, lid side down.
• Step back and watch what happens!

Observation: Observe the canister as the reaction happens. What do you see and hear? How high does the rocket go?

Results: Record the outcome of your experiment. Was the launch successful? How high did your rocket fly? Did it happen as you predicted?

Conclusion: Explain why the rocket moved. The reaction between baking soda (a base) and vinegar (an acid) produces carbon dioxide gas. This gas builds up pressure inside the canister until the lid pops off, pushing the rocket into the air. This is an example of Newton’s Third Law of Motion: for every action, there is an equal and opposite reaction.

Experiment with different amounts of vinegar and baking soda to see if it affects how high your rocket goes. You can also try different sizes of containers to see how they change the reaction.

This experiment is not only a thrilling demonstration of a chemical reaction but also a fun way to learn about forces and motion. Make sure to conduct it in a safe environment and wear your safety goggles to protect your eyes. Enjoy your scientific journey into rocketry!

5. Magnetic Magic – Magnetic Poles and Fields Experiment

Introduction: Explore the invisible world of magnetism with this engaging experiment! Perfect for first and second graders, this activity will help you understand how magnets work, focusing on the poles and the magnetic fields they create. You’ll need some common items from home or school and the help of an adult to guide you through.

Objective: To explore and visualize the magnetic field lines around bar and horseshoe magnets and understand the interactions between the different poles of magnets.

• 1 bar magnet (with North and South poles labeled)
• 1 horseshoe magnet (with North and South poles labeled)
• Iron filings
• A sheet of white paper
• A tray or cardboard to contain any mess
• A compass (optional, for further exploration)

Hypothesis: Before you start, think about what you might see when you sprinkle iron filings around the magnets. What do you think will happen when the North pole of one magnet is near the South pole of another? Write down your guess.

• Place the sheet of white paper on the tray or cardboard to keep your workspace clean.
• Lay the bar magnet and the horseshoe magnet on the paper. Start with them a good distance apart so their fields don’t overlap immediately.
• Gently sprinkle iron filings around and between the magnets. Be careful not to bump the table as the filings align themselves along the magnetic field lines.
• Look at how the iron filings arrange themselves around each magnet. Notice the patterns they form. These lines show the magnetic fields emanating from the poles.
• Slowly move the North pole of one magnet towards the South pole of the other. Observe how the iron filings react. Do the same with like poles (North to North or South to South) and note any differences.

Observation: Record what happens to the iron filings as you move the magnets. How do the patterns change? What does this tell you about how the magnetic poles interact?

Results: Describe the arrangement of iron filings and what it indicates about the magnetic fields. Note any changes when different poles are near each other.

Conclusion: Explain your observations in terms of magnetic poles and fields. Magnets attract when opposite poles are near each other and repel when like poles are close. The iron filings align themselves along the lines of magnetic force, visibly showing the shape of the magnetic fields.

Try using a compass to see how the needle aligns with the magnetic fields. You can also test different materials to see if they are influenced by the magnets, like clips, aluminum foil, or copper wire.

This experiment not only teaches you about magnetism but also lets you see the invisible forces at play. Have fun exploring and always make sure to clean up your space when you are done!

6. DIY Lava Lamp Experiment

Introduction: Ready to light up your curiosity with a colorful DIY Lava Lamp? This experiment is fantastic for young scientists in first or second grade to explore the interactions between oil, water, and effervescent tablets. This safe and simple project is sure to dazzle and teach important scientific concepts with a bit of adult help.

Objective: To understand the effects of density and chemical reactions by creating a homemade lava lamp.

• 1 clear plastic bottle (1 liter)
• Water (about 400 ml)
• Vegetable oil (about 600 ml)
• Food coloring (any color you like)
• Effervescent tablets (like Alka-Seltzer)
• Flashlight (optional, for effect)

Hypothesis: Think about what will happen when you mix oil, water, and the effervescent tablet in the bottle. Predict how the ingredients will interact and what will happen when you add the tablet.

• Fill the clear plastic bottle with 400 ml of water.
• Slowly pour 600 ml of vegetable oil into the bottle, allowing it to layer on top of the water.
• Add a few drops of food coloring to the bottle. The drops will pass through the oil and mix with the water below.
• Break an effervescent tablet into a few pieces.
• Drop one piece into the bottle and watch as the lava lamp effect begins. The tablet reacts with the water to create gas bubbles that rise and fall through the oil.
• Shine a flashlight through the bottom of the bottle to enhance the visual effect, especially in a dim room.

Observation: Watch the bubbles of colored water rise and fall in the oil as the gas bubbles form and pop. Note how the oil and water do not mix.

Results: Describe what you see when the effervescent tablet reacts in the water and how it affects the oil and water mixture.

Conclusion: Explain the science behind the lava lamp. The water and oil separate due to their different densities, with oil being less dense and sitting on top of the water. The effervescent tablet reacts with the water to create carbon dioxide gas, which carries the colored water up through the oil until the gas escapes at the top.

Try using different amounts of oil or water, different colors of food coloring, or different types of effervescent tablets to see how it changes the reaction.

This experiment not only makes for an eye-catching display but also helps understand concepts like density, solubility, and gas formation. Have fun watching your very own lava lamp glow!

 7. Dancing Raisins Experiment

Introduction: Get ready to watch raisins dance in this fun and simple science experiment perfect for young students in first or second grade. This activity demonstrates the principles of buoyancy and gas production in a way that’s both entertaining and educational, with just a bit of adult supervision needed.

Objective: To observe and understand why raisins move up and down in a fizzy liquid due to the formation of gas bubbles.

• 1 clear glass or transparent plastic cup
• Plain water (enough to fill the glass three-quarters)
• Carbonated clear soda (enough to fill the glass)
• Several raisins (4-6)
• A stopwatch or timer (optional, to record the duration of the dance)

Hypothesis: Before starting, predict what will happen when you drop raisins into the soda. Do you think they will sink, float, or dance? Write down your guess.

• Fill the glass three-quarters with plain water and top it off with carbonated soda to make the liquid fizzy.
• Carefully drop 4 to 6 raisins into the glass of fizzy liquid.
• Watch what happens to the raisins for the next few minutes. Observe how they move in the glass.

Results: Record your observations. Do the raisins sink, float, or dance up and down? How long do they continue moving?

Conclusion: Explain the results using the concept of buoyancy and gas production. The carbon dioxide bubbles from the soda attach to the rough surface of the raisins, making them buoyant enough to rise to the surface. Once they reach the top, the bubbles pop, and the raisins sink again. This cycle repeats, causing the dancing effect.

Experiment with different carbonated drinks or try other small, dried fruits or objects like corn kernels or small pasta shapes to see if they also dance. Explore how temperature affects the rate of dancing by using cold versus room temperature soda.

This experiment is a fantastic way for kids to visually grasp scientific concepts and enjoy the magic of simple chemical reactions. It’s perfect for a science fair project or a classroom activity!

8. Color-Changing Carnations

Introduction: Discover how flowers drink water with the Color-Changing Carnations Experiment! This visually stunning activity is perfect for first and second graders to learn about plant biology and capillary action in a fun and colorful way. It’s a simple experiment that requires some adult supervision.

Objective: To demonstrate how plants absorb water and nutrients up through their stems, using carnations and colored water.

• White carnations (several, depending on how many colors you want to test)
• Clear glasses or vases (one for each color)
• Food coloring in various colors
• Scissors (to be used by an adult)

Hypothesis: Predict what will happen when the carnations are placed in colored water. Which colors do you think will show up best in the petals?

• Have an adult trim the stems of the carnations at an angle to allow them to absorb water more efficiently.
• Fill each glass or vase with water and add about 20 drops of food coloring to each, choosing different colors for each container.
• Stir the water to evenly distribute the color.
• Place one carnation in each colored water vase.
• Observe the carnations daily to see how the color travels up the stem and changes the color of the petals.

Results: Record your observations over several days. Note the changes in the color of the petals and how quickly each color appears.

Conclusion: Explain how capillary action works in plants, drawing water and nutrients up through tiny tubes in the stem. The food coloring shows this process visually, changing the color of the carnations’ petals.

Try using different liquids like sports drinks or diluted inks to see if they affect the flowers differently. Experiment with other white flowers to see if they absorb colors faster or slower than the carnations.

9. Invisible Ink

Introduction: Send secret messages with the Invisible Ink Experiment! This project is a fantastic way for first and second graders to learn about chemical reactions and the properties of acids and bases, with just a bit of adult supervision for safety.

Objective: To use a natural acid (lemon juice) to write invisible messages that appear only when heated.

• Spoon or brush
• White paper
• Heat source (light bulb or hair dryer; an adult should handle this part)

Hypothesis: Guess what will happen when you heat the paper that has lemon juice on it. How do you think the message will appear?

• Squeeze lemon juice into a bowl and add a few drops of water.
• Dip the spoon or brush into the lemon juice mixture and write a message on the white paper.
• Allow the paper to dry completely, making the message invisible.
• Have an adult help you heat the paper using a light bulb or hair dryer. Watch as the message slowly appears.

Results: Record what happens when the paper is heated and how clearly the message shows up.

Conclusion: Explain why the lemon juice message appears when heated (lemon juice, being acidic, weakens the paper fibers slightly and caramelizes when heated, making it visible).

Experiment with other natural acids like orange juice or vinegar. Try different heating methods or papers to see which reveals the message most effectively.

10. Homemade Slime Experiment

Introduction: Get ready for gooey fun with the Homemade Slime Experiment! This engaging and tactile project is great for first and second graders to learn about polymers and non-Newtonian fluids. Adult supervision is recommended, especially when handling chemicals.

Objective: To create slime using simple household ingredients and explore its unique properties.

• White school glue (about 120 ml)
• Borax powder (2 teaspoons)
• Water (two cups)
• Food coloring (optional)
• Mixing bowl

Hypothesis: Predict what will happen when you mix glue, borax, and water. What kind of texture do you think your slime will have?

• In a mixing bowl, combine 120 ml of white glue and one cup of water. Add a few drops of food coloring if desired.
• In another container, dissolve 2 teaspoons of borax in one cup of warm water.
• Slowly add the borax solution to the glue mixture, stirring continuously.
• Keep stirring until the slime begins to form and pull away from the sides of the bowl.
• Take the slime out and knead it with your hands until it reaches the desired consistency.

Results: Describe the texture and behavior of your slime. Is it stretchy? Does it bounce?

Conclusion: Discuss the chemical reaction between the glue and borax that creates a polymer, which gives the slime its unique properties.

Try adding different amounts of borax or glue to see how it changes the slime’s properties. Add glitter, beads, or small toys to create different types of slime.

Each of these experiments offers a fun, educational way to engage with basic scientific concepts, perfect for young learners eager to explore the world through science.

That’s a Wrap!

Science is all about curiosity, discovery, and having fun while learning how the world works. Through these 10 experiments, young scientists have not only created colorful reactions and gooey slime but also gained a deeper understanding of important scientific principles. Whether it was watching a volcano erupt, making an egg float, or exploring the magnetic fields, each experiment has shown that science is everywhere—even in the simplest things around us. As you continue to explore and experiment, remember that the journey of discovery is just beginning. Keep asking questions, keep experimenting, and most importantly, keep having fun with science!
