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.
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.
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!
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!
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.
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.
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.
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.
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.
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.
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.
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!
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.)
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!
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.
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.
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.

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

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

No for an experiment in sound!
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.
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.

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.

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.

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.

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.

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.

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!
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!

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.

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.
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.
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 .
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.
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 .

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.
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.

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!
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 .
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 .
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 .

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 .
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 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 .
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
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.
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 .

The way that the world works is completely fascinating. After trying a few of these experiments with your kids or class, you’ll find that the kids naturally want to learn more and more.
Soon, you’ll be learning from the kids as they share their latest scientific findings with you.
Try these super easy science experiments at home or in the classroom today!

If you’re not a science teacher, you may wonder what the point of doing science experiments with kids is. Isn’t that why they have science class?
Aside from these easy science experiments being fun for the classroom, I also like to do them at home for a few different reasons.
First, science experiments are really fun. If you haven’t made a chemical reaction since you were in high school, you may be surprised at just how much fun it can be. You may find you have just as much fun as your kids when doing these experiments.
Second, kids learn best when they can do things hands-on. Science can be a difficult concept for kids to grasp, but for kids who are introduced to the study in a hands-on way, they are more open to learning the “boring” side of science, which improves their grades and mental well-being in science class.
You may just find that you’re raising the next big scientist of your child’s generation.

Every science experiment contains four elements. When doing a science experiment, no matter how easy, try to include all of these elements to distinguish it from a science demonstration and turn it into a real science experiment.
When you include all these elements, you have a real experiment!
Science demonstrations can be fun too, but the more variables and tests you have, the better of an experiment you have! Science is just more fun when you try new and different things.

Keep these science supplies on hand to make these experiments even easier! This post contains affiliate links.
When you pick your science experiment, start with something easy if it’s your first time. One of the easiest science experiments ever is the tornado in a jar.
Make sure you have all supplies on hand, and take a few minutes to go over the science lesson before starting the project.
I find it’s best to explain the science before you get started as kids might stop paying attention once the experiment begins.
Whether you are doing these easy science experiments as science demonstrations or science experiments, your kids will have a blast either way! These science projects are easy either in that they don’t take much time, or that they are simple enough to do at home.
Even if you are new to science experiments, you’ll be able to complete these science activities with ease!

All plants need water, sunlight and a home to live in (usually in the ground), but some plants, like cacti, need less water than others (that’s why they grow in the desert). Here you’ll explore how plants grow in different environments.
What you’ll need
-1 packet of radish/cress/mustard seeds
-3 small plastic pots
-Soil to fill the 10 pots
-1 measuring cylinder
-1 notebook
Fill the three pots with the same amount of soil, and place approximately five seeds in each pot.
Add 25ml of water to each pot.
Place one pot in the cupboard, one in the fridge and one on your windowsill.
Each morning and evening for about a fortnight, add 25ml of water to the pot, and make a note of anything you notice about your plants.
Why it works
You should expect to see the healthiest looking plant has been grown on the windowsill. This is because while all the seeds had soil and water, only the seeds on the windowsill had access to light, a key component in order to grow.
There are three types of rock: igneous , sedimentary , and metamorphic . Igneous rocks form as a result of the cooling of magma (lava). When magma cools and hardens, it becomes a rock. Sedimentary rocks are a mixture of other materials that have been re-deposited, and re-solidified through compression and cementation . Metamorphic rocks are types of existing rocks that have been altered in form as a result of changes in heat and pressure. See which ones you can identify in this experiment!
– A magnifying glass
– A mixture of rocks found from as wide an area of locations as possible
– Good lighting (so you don’t’ strain your eyes)
– Sticky notes to label each rock
– Notebook
– Pen
Label each rock with a number so when you record your findings, you can easily identify which rock you’re commenting on.
Choose a labelled rock.
Look at it through the magnifying glass.
Look carefully for crystals and other structures within the rock that could determine what it is.
Make a note of what you can see from each rock using your notebook of your findings.
Why it works
Igneous rocks are easily identifiable because they contain angular crystals. The longer the igneous rocks take to cool and crystallise, the larger the crystals will become. Sedimentary rocks generally have more of a layered appearance because of the different rock types being pressed together. Metamorphic rocks can look layered, but the layers often aren’t continuous and they tend to be very small scale. The rock will look like one fused mass rather than separate crystals.
Have a think, what would each rock be best used for? Can you identify where we use rocks?
The aim of this experiment is to prove that plants do take in water.
– 2 sticks of celery or white-petal flowers, (such as carnations)
– 2 empty glasses
– A food colouring of your choice (red or blue is best)
– Knife (your guardian will need to use this)
– Water
– Notebook
Using a sharp knife, (ask your guardian to help) cut roughly 2cm off the bottom of the celery sticks.
Fill one of the glasses roughly 1cm high with food colouring and add an extra 0.5cm of water to it. Fill the second glass with just 1.5cm of plain water.
Place the freshly chopped end of one of the celery sticks (or carnations) in the water.
Place the other in the clear water and leave overnight.
You should find that the leaves of the celery (or carnations) have become a colourful work of art! This proves that the plant has taken up the coloured water you made.
you can also share your experiments online as you go using the hashtag #flsciexp16., leave a comment.
Your comment will be checked and approved shortly.
Can you post the mug cake one!!!
they actually work. im impressed.
OMG! Tried the flower one at school and it worked so well!! Don't use faint colours though like pink or yellow. They don't work but we used a white rose and blue food colouring!! It worked so well! I RECOMEND IT!!!
i luv experimenting
I all ready did the cress experiment when I was in year1/class2!
Im definitely going to try the last one its so cool!
wow what a nice experiment
wow what a good experiment i will do this in my science exhibition
i love making experiments! ill try to dye some carnations for my birthday party.<3
best trick ever espesily the food colouring one
cool especially the flowers/celery
cool experiments ive tried some of them with my grandma in her garden
Some of the experiments are a bit tricky because they request a few items that I cant get hold of easily.

Experiment #12: How to Make a Tornado in a Bottle
Learn how a vortex is formed and why tornadoes can be so dangerous with this colorful & mesmerizing science project that uses items you have around the house!
20 Science Experiments You Can Do in a Jar
How to Make a Barometer & Measure the Weather
You can create your own tornado in a bottle. All you need are two bottles, a tube to connect the bottles, and some water.
By swirling the liquid in the top bottle, you can create a vortex as it drains into the bottom bottle. That's because as the water flows down, air must flow up, creating a spiraling tornado.
You can even add glitter, food dye, or lamp oil to the bottle to make the tornado even cooler.
This experiment takes advantage of density to create a rainbow in a glass. When you add sugar to a liquid, it causes the solution to become more dense. The more sugar you add, the denser the solution becomes.
If you have four different solutions that are all different colors and densities, the colors will layer on top of each other — the denser, more sugary solutions will sit on the bottom and the lightest will sit on the top.
Mix glue, water, and some food coloring together. Then add some borax and a gooey slime forms. That's because the glue contains polyvinyl acetate, a liquid polymer. The borax links the polyvinyl acetate molecules to one another, creating one large, flexible polymer: slime.
Believe it or not, you can create a very simple hybrid rocket engine using nothing but some yeast, hydrogen peroxide, a jar, fire, and ... a piece of uncooked pasta.
When you mix the yeast and hydrogen peroxide together, they react and create pure oxygen gas. When this gas is funneled through a piece of pasta, all you need is a little bit of fire and you've got yourself a pasta rocket.
Alka-seltzer is great if you're suffering from heartburn or an upset stomach. But you probably didn't know it's also great if you're looking to create your own homemade lava lamp.
Because oil and water have different densities and polarities, when you mix them together, the water sinks to the bottom. When you add food coloring, which is water-based, it will sink to the bottom as well.
If you pop in an Alka-Seltzer tablet, it reacts with the water, causing colored droplets of water to rise to the top. As they rise, they pop, release air, and sink back to the bottom.
This creates a similar effect as what you'd see in a lava lamp.
In order for water to become ice, it needs a nucleus for solid crystals to form. Usually, water is loaded with particles and impurities that enables ice to form. But purified water isn't, which means it can reach an even colder temperature before becoming solid.
If you throw an unopened bottle of purified water into the freezer for a little less than three hours, the bottle will be chilled well below the temperature at which regular water freezes.
When you pour this super-cooled water onto a piece of ice, it provides the water with nuclei, causing it to freeze instantly.
This experiment makes it easy to see magnetic fields in action . All you need is some iron oxide, some water, and a jar.
When you place a powerful magnet along the outside of the jar, the iron filings are attracted to it. They pile up and follow the magnet as you move it around.
In this experiment, a chemical reaction between baking soda and vinegar creates "lava" that bursts out of a model volcano.
As the reaction produces carbon dioxide gas, pressure builds up inside a plastic bottle hidden inside the volcano until the gas bubbles and erupts.

I created a cheat sheet for these experiments, with the supply lists and a quick set of directions. I also included a supply list for all of the experiments, in case you want to shop once and then do them all one by one.
Alright, on to the experiments!
What you’ll need:
Directions:
You’ll soon start to notice the raisins “dancing.” The carbon dioxide bubbles will cause the raisins to rise to the top of the glass, and then as the bubbles pop, the raisins will sink back down.
Keep going! How many bubbles can you make inside the first bubble? Emma and Kate also enjoyed dipping their hands into the mixture, and then having me blow bubbles right onto their hands.
You’ll start to see a rainbow forming within seconds of pouring the hot water. It’s pretty cool, and once the water cools you can still eat the Skittles. 😉
Oobleck is a ton of fun to play with. Kids love to let it dribble off of their fingers, or to try to hit it as hard as they can (at which point it becomes rock hard!) Have fun experimenting with it, but fair warning- it can get messy. We like to do this one outside… right before bath time!
The second egg floats because you increased the density of the water by adding salt. Now the raw egg is less dense than the water it’s in… so it floats!
The colored water will travel up each paper towel, and into the empty cups. You should end up with a rainbow of colors by the end of the day.
You can repeat this experiment as many times as you want. Just keep adding more Alka-Seltzer. My kids also enjoyed using a flashlight to “light up” their lava lamps.
The vinegar breaks down the egg shell, leaving only a thin, rubbery membrane. If you hold the egg up to the light, you can even see the yolk inside.
You should see the bag start to blow up with Carbon Dioxide. Eventually, it gets too full, and will burst with a POP! This is a good outdoor experiment, so you don’t have to clean up a mess afterwards.
The colors will start moving right away. You can dip the swab back into the dish soap and into the milk mixture again several more times, and it will continue to react.
As soon as the mixture cools, you can gather the clumps and play with them like Silly Putty. You can even mold the plastic milk into a shape and let it harden overnight.
This is a great experiment for kids who love to be grossed out. My kids thought it was disgusting… and were thoroughly fascinated by it!
The baking soda/vinegar reaction produces bubbles that are filled with an invisible gas: Carbon Dioxide. Even after the reaction is over, your measuring cup will still be filled with Carbon Dioxide. Even though you can’t see the gas, you can still pour it. And when you pour it onto a flame, it acts like a fire extinguisher! My kids thought I was doing magic. Pretty cool.
My kids loved feeling the fluffy soap after it came out of the microwave, but be careful! It will be pretty hot, so you’ll want to give it some time to cool down first.
The dollar bill burns, but doesn’t burn up! Make sure that you’re extra careful with this one- you will get some impressive flames. (Hold the burning bill far away from yourself, your kids, and anything flammable.)
With any luck, you’ll get the egg to drop straight into the glass of water without cracking! If you’re nervous, though, you can always practice with a tennis ball before you move on to the raw egg. 😉
Fair warning: you’ll be shaking for a while! But eventually you’ll start to notice that the whipping cream has separated into a blob (the butter) and a watery liquid (the buttermilk.) Take out the blob, add a little salt, and you’ve got yourself some delicious butter!
This is so simple, but for some reason, my kids thought it was so funny! The gummy bears swell up and get really slimy. They loved playing with them afterwards.
Have fun with these science experiments, and if you haven’t already, don’t forget to download your supply list here.
Happy experimenting!

Awards Grant Greater Access to Nuclear Science User Facilities Resources and Capabilities
WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today awarded 13 Super Rapid Turnaround Experiment (RTE) user access projects to examine the performance of promising nuclear fuels and materials that support the nation’s current fleet of reactors and advance next-generation nuclear technologies.
Super RTE awards advance nuclear science and technology by providing researchers timely access to irradiation testing, post-irradiation examination, high-performance computing, and technical expertise.
Awardees will have up to a year to complete experiments using world-class testing capabilities provided through the Department’s Nuclear Science User Facilities (NSUF) program. These capabilities are equal to approximately $1.8 million in support and are provided at no cost to the researchers.
“Our national labs house unmatched nuclear science infrastructure and expertise,” said Acting Assistant Secretary for Nuclear Energy Dr. Michael Goff . “Access to these capabilities helps speed the research and development of materials and fuels needed to achieve the Biden-Harris Administration’s ambitious plans for the future of nuclear energy.”
The selected project teams include 13 principal investigators from 6 universities, 2 national laboratories, and 1 industry partner who will work with NSUF on the proposed experiments.
The projects will advance the development of nuclear fuels and materials such as silicon carbide composites, TRISO fuel, and advanced stainless steel. Projects will also research manufacturing and welding technologies for potential use in current light-water reactors and future advanced nuclear reactors. A complete list of the awarded projects can be viewed HERE .
The Super RTE solicitation is similar to NSUF’s traditional RTE solicitation, but it encourages larger scopes of work and allows researchers more time to perform tests. Awardees are also provided greater access to NSUF partner institutions, resources, and facilities, allowing for more complicated experiments.
The third and final round of traditional RTE awards for fiscal year 2024 will be announced later this fall. NSUF plans to issue another Super RTE solicitation in 2025.
NSUF advances DOE’s Office of Nuclear Energy’s mission through a consortium of state-of-the-art irradiation and post-irradiation testing facilities that can be utilized to support nuclear energy research and development. More information on NSUF and user access opportunities can be found HERE .

Three teams of secondary school pupils from Estonia, Japan and the United States have been selected to carry out their own experiments using accelerator beams at CERN and DESY
25 June, 2024
Winners of the 2024 CERN Beamline for Schools competition: Sakura Particles” from Japan (left), “Mavericks” from Estonia (top right) and “SPEEDers” from the USA (bottom right) “(Images: Sakura Particles, Mavericks, SPEEDers)
Geneva and Hamburg, 25 June 2024. Beamline for Schools (BL4S) is a physics competition run by CERN , the European laboratory for particle physics, open to secondary school pupils from all around the world. Participants are invited to prepare a proposal for a physics experiment that can be undertaken at the beamline of a particle accelerator, either at CERN or at DESY (Deutsches Elektronen-Synchrotron in Hamburg, Germany). In 2024, three winning teams have been chosen, based on the scientific merit of their proposal and the communication merit of their video.
“Mavericks”, a team from the Secondary School of Sciences in Tallinn and the Hugo Treffner Gymnasium in Tartu, Estonia, and the team “Sakura Particles”, which brings together pupils from Kawawa Senior High School in Kanagawa, Joshigakuin Senior High School and Junten High School in Tokyo, Kawagoe Girls High School in Saitama and Kitano High School in Osaka, Japan, will travel to CERN in September 2024 to perform the experiments that they proposed. The team “SPEEDers” from Andover High School in Andover, USA, will carry out their experiment at a DESY beamline.
A beamline is a facility that provides high-energy fluxes of subatomic particles that can be used to conduct experiments in different fields, including fundamental physics, material science and medicine.
BL4S started in 2014 in the context of CERN’s 60th anniversary. Over the past 10 years, more than 20 000 pupils from all over the world have taken part in the competition, and 25 teams have been selected as winners. The participation rate has been rising consistently over the years, with a record 461 teams from 78 countries submitting an experiment proposal in 2024.
“Preparing a proposal for a particle physics experiment is a very challenging task. The success of Beamline for Schools shows that, when provided with the right support, high-school students can design feasible, interesting and imaginative experiments,” says Charlotte Warakaulle, CERN Director for International Relations. “We are continuously impressed by the quality of the proposals, and this year is no exception. The candidates demonstrated impressive creativity and great rigour, two essential qualities for students who might decide to take up scientific careers.”
The fruitful collaboration between CERN and DESY started in 2019 during a long shutdown period of the CERN accelerators. This is the sixth year that the German laboratory has hosted competition winners.
“Every year I am very impressed by the creativity and determination of the team members,” says Beate Heinemann, Director in charge of Particle Physics at DESY. “I am already looking forward to hosting the team from the USA this year. This programme is so important to me as it advances not only science but also the cultural exchange between young people from different nations.”
“Our experiment will focus on detector development for high-altitude ballooning applications,” says Saskia Põldmaa, one of the “Mavericks” members, from Estonia. “This is by far the biggest opportunity we have had so far in our lifetime so we will hold onto it dearly. We can’t wait to calibrate our homemade muon detector!”
“Our team focuses on detector development for muon tomography applications. We will test and optimise our homemade two-dimensional position-sensitive detector,” says Chiori Matsushita from the Japanese “Sakura Particles” team. “CERN has always been a dream for us. Finally getting to go there, not as a tourist but to do experiments, is amazing!”
“We focus on beam diagnostics: our aim is to measure and analyse the Smith-Purcell (SP) radiation emitted by different diffraction gratings when DESY’s electron or positron beams pass by,” says Niranjan Nair from the US “SPEEDers” team. “We are thrilled to have the opportunity to not just watch scientific advancement passively, but actively contribute to it at DESY: the ultimate goal of our experiment is to research SP radiation as a tool for beam diagnostics.”
The winning proposals were selected by a committee of CERN and DESY scientists from a shortlist of 49 particularly promising experiments. In addition, three teams will be recognised for the most creative video proposals and another 13 teams for the quality of physics outreach activities they are organising in their local communities, taking advantage of the knowledge gained by participating in BL4S.
Beamline for Schools is an education and outreach project funded by the CERN & Society Foundation ’s donors. This 11th edition is supported notably by ROLEX through its Perpetual Planet Initiative and by the Wilhelm and Else Heraeus Foundation.
