Science Struck

A Really Interesting List of 6th Grade Science Experiments

Science experiments help kids understand certain basics and fundamentals of science in a fun way. Experiments are set up according to their level and skills. In this ScienceStruck article, you shall find some topic ideas and experiments for 6th grade students.

Like it? Share it!

Reaching 6th grade is fun because then you become eligible to perform middle school experiments that may capture your interest a lot. Performing science experiments is not only interesting, but it also develops analytical skill that may prove useful in the future when working on research projects. Students are enthusiastic about performing science experiments because it gives them the opportunity to exhibit their analytical and creative skills.

Science Experiments for 6th Graders

You should go through the laboratory safety guidelines and the procedure for handling the laboratory equipment before starting any experiments to avoid any mishaps. In 6th grade, students are allowed to handle instruments and samples that are safe, and do not involve any risks. Handling fire or strong chemicals is usually not a part of 6th grade projects. Here are some fun science experiments for 6th graders.

The Egg Experiment

This is one of the most commonly used substance for 6th grade science experiments. With eggs students can learn rules and laws of science. They can perform a number of practicals, that can include observation of eggs sinking or floating on changing the density of the water, or the difference in composition of hard-boiled eggs and raw eggs.

Set up the experiment in different containers. The first containing plain water, the second containing sugar and the third containing salt. Now, dip the eggs in each container and record the results. Try to analyze the results with the help of your teacher. You can also find out the differences between hard-boiled eggs and raw eggs by allowing it to spin.

Evaporation of Water

In this science activity you will determine the rate of evaporation of water under different intensity of light. You will have to construct several boxes installed with electric bulbs having different wattage. The containers are simultaneously filled with water and the bulbs are lit. You also need a controlled experiment that will be devoid of bulb. You will notice that the rate of evaporation is highest in the container having maximum power of bulb. This happens because water changes to vapor form more quickly under intense temperature. Since the surrounding temperature of the bulb with highest power is more, so the rate of evaporation is also more.

Make a Periscope

A periscope can be used to see objects when you are in a concealed position. To make one, you will require two pipes, at least 10 inches long. The diameter of one pipe should be slightly larger than the other, so that one can slide over the other. You’ll need 2 elbow joints, each matching the diameter of either pipes. Also you’ll require 2 circular mirrors, along with some super glue.

To begin with, stick the mirrors in the elbow joints at a 45 degree angle. This is the precise angle that reflects the light is such a way that it lets you see the best view. Now, fix the appropriate pipe into the respective elbow joints. Finally, slide the larger pipe on to the smaller one, and your periscope is ready to use.

Inflate a Balloon by Itself

This is a fun experiment that teaches you how a chemical reaction can inflate a balloon. You’ll be needing a small balloon, a test tube, vinegar, funnel, and a teaspoon of baking soda.

Fill the test tube half way with vinegar. Then, stretch the balloon a bit, and use the funnel to pour the baking soda into it. Now, carefully stretch the opening of the balloon over the mouth of the test tube and ensure that the baking soda does not fall in the tube. Once you’ve ensured that the balloon snugly fits over the mouth of the test tube, lift the balloon and tap it, so that the baking soda falls into the vinegar.

When the baking soda falls into the vinegar, the solution turns into carbonic acid. This makes it unstable, and it releases carbon dioxide, which rises up and inflates the balloon.

Make it Rain

This simple experiment is a fantastic way to learn how the changes in temperature bring about rain. You’ll need a glass jar, some steaming hot water, a dish big enough to be placed over the jar, and some ice cubes.

Pour the boiling water into the jar, filling about a third of the space. Place the plate on top of the jar, and wait for a couple of minutes. Put the ice cubes on the plate, and observe what happens inside the jar. You’ll begin to see droplets of ‘rain’ sliding along the sides of the jar.

55 Super Fun Science Fair Projects For 6th Graders

Categories Activities & Ideas

Science is so fascinating, but it can sometimes be difficult to convince 11-year-olds that this is the case.

In order to capture their attention, you need to come up with something that will not only educate them, but also entertain them.

Below, we have listed 55 super fun science fair projects that 6th graders will love to try.

1. Carbon Sugar Snake

To start off this list, here’s an experiment that focuses on three heat-dependent chemical reactions. 

By lighting up some baking soda and sugar with a match, you can create a ‘snake’ made from carbon and sugar that continues to grow for up to 20 minutes!

2. Turn Milk into Plastic

With this experiment, you can teach your kids how to make plastic from lots of different materials, even including milk.

Once you’ve created the milky plastic, you can even melt and mold the organic casein polymer to make a new product.

3. Which Wheel Works Best?

This is a great way to teach kids about acceleration and velocity, and how the material of a wheel can affect the speed and resistance of a skateboard.

We don’t recommend trying this experiment if you’re not a very good skateboarder, however, as this could potentially result in injury.

4. Baking Soda-Powered Boat

By assembling a plastic bottle with some vinegar, baking soda, and a straw, you can create your very own mini speedboat.

The idea behind this experiment is very similar to making a baking soda volcano, as the chemical reaction creates pressure and movement.

5. Two-Stage Balloon Rocket

This is another experiment that kids can have lots of fun with, as well as learning all about how it works.

By attaching a balloon to the back of a straw, you can pump it up and release it across the room, allowing it to soar like a real life rocket.

6. Tiny Dancers (A Homopolar Motor)

By attaching a couple of wires and magnets to an AA battery, you can create your very own spinning ballerina!

You can even add some colorful crêpe paper to give your tiny dancer its very own tutu. Get creative, and learn all about how your dancer is spinning. 

7. Magic Spinning Pen

Magnets are some of the coolest tools ever, especially when you know how to use them to create fun tricks like these.

To create this magical spinning pen, you’ll need to use some small rods, a pen, a coin, and, of course, a couple of magnets.

8. Homemade Wigglebot

Did you know that you can make your very own robot using a plastic cup with googly eyes? This ‘robot’ can walk around all on its own!

This is another experiment that will teach your children how batteries work alongside motors.

9. Electromagnetic Train

Next up, we’ve got a science project that is so easy to set up, yet it will keep your kids entertained for hours.

An AAA battery attached to some magnets will become an electromagnetic train when placed at the entrance of a copper wire tunnel.

10. Holiday Card Circuits

Say goodbye to your run-of-the-mill handcrafted Christmas cards, and say hello to these impressive holiday card circuits.

By building a super simply circuit and taping it onto some cardboard, you can bring your festive designs to life… or, should we say, ‘to light ’? 

11. How to Make Fizzing Lemonade

Everybody loved carbonated drinks, but not everyone knows how they work. Where do the bubbles come from?!

Use this experiment to teach your kids (and yourself) how a chemical reaction using acid can turn your still drink into a bubbly one.

12. Solar-Powered Robot Bug

This solar-powered robot bug is also known as a ‘frightened grasshopper’. Why? Because it’s scared of the light!

Once you’ve assembled your robot bug, witness how it runs around when exposed to light, but comes to a standstill once it has been covered in shade.

13. Homemade Coffee Can Camera Obscura

Have your kids ever wondered how a camera works, or do they just accept it for what it is? If so, now is the time to teach them.

This camera is so easy to make from coffee cans and construction paper, and is so interesting and fun to use.

14. Heat Sensitive Color Changing Slime

From mood rings to heat-sensitive lip gloss, it is always impressive when an object can change color. This is all thanks to thermochromic pigment.

Add some thermochromic pigment to homemade slime made from white glue and liquid starch, and watch the magic happen.

15. DIY Crystal Landscapes

Have you ever seen anything as pretty and colorful as these vibrant crystal landscapes? You will find it surprising how easy they are to make.

You’re going to need to mix together some liquid bluing with water, salt, coloring, and ammonia to create these beautiful crystal creations.

16. Glow in the Dark Jello

Uh, hello? Glow in the dark Jello? Just when you thought that jello couldn’t get any more fun and yummy, this edible experiment pops up.

Boil some light-colored Jello with tonic water, let it cool in a mold, and then turn the lights out for the real fun to begin. 

17. How Do Roots Grow When the Direction of Gravity Changes?

We all know that gravity is what keeps our feet weighed to the ground, but what about plants? Does gravity affect the way they grow?

Make your own scientific container (made from a CD case), add some seeds, and switch up the directions every so often to test out this theory.

18. Seafloor Spreading Model

If you want to create a fun lesson plan to teach your students about the lithosphere, and how earthquakes occur, this is a great project to try out.

You will need to cut up a lot of paper for this project, so you can decide whether to do this beforehand, or to allow your students to fully make the project themselves.

19. The Science Behind Tsunamis

Tsunamis are terrifying natural occurrences, regardless of whether your hometown and country is at risk of them. 

Sometimes, learning about something can make it seem less scary. Teach your students about tsunamis using this experiment.

20. How Acidic Waters Make Rocks Disappear

It seems impossible to imagine that rocks can become worn down by water over time. With this project, you can work out how it happens, and why.

This is a great way to teach students about the effects of acidic water, and how stone can gradually become worn down and dissolved. 

21. Ice Cube vs. Wire

How could it be possible that one thin piece of wire could cleanly slice through an ice cube while leaving the rest of it intact?

Use a piece of wire and an ice cube to test the strange physics of water. To increase the fun, ask your students to guess how long it will take for the wire to split the cube.

22. DIY Heart Pump

Our bodies are fascinating vessels, and it can be so interesting to learn exactly what is going on inside ourselves.

This DIY heart pump may be a little fiddly to piece together, but once complete, you can show your students what is really going on inside their chests.

23. Engineering a Bridge

Engineering is a super fun and handy skill to have, whether it is something you want to make a career out of, or you’re just a crafty kind of person.

Use this sheet to ask your students how many popsicle sticks they think will need to create a sturdy bridge. Then, put their ideas to the test.

24. Earthquake Science Project

As we said earlier, sometimes knowing more about something (e.g., an earthquake) can make it seem a little less scary. 

This project involves creating sturdy structures, and then using books as a foundation to represent the earth’s plates. See how long your structures will stay standing, and work out how to improve them.

25. Magic Cloud in a Bottle

When we were kids, we thought clouds had the same texture as cotton candy, or the inside of a pillow. Nowadays, we know differently… but, do your students?

Teach them what a cloud really is by using rubbing alcohol and a pump to recreate what it really is, but in a smaller form.

26. Pop Rocks and Soda Science Experiment

Popping candy is so fun to eat, but do you know how it works? Why does it start popping when it goes into your mouth? (More on that later.)

For now, here is a fun variation on the ‘coke and Mentos’ experiment. Add some Pop Rocks into a bottle of soda, and see what happens…

27. Biodomes Engineering Design Project

By getting your students to design their very own biodome, they can learn more about how an ecosystem works.

You’re going to need some soil, seeds, sand, rocks, and even some creepy crawlies. Add them all into a plastic bottle, and take notes of what occurs inside.

28. Displacement and Buoyancy in Metal Boats

Archimedes’s principle, or the law of buoyancy, explains why some objects sink in water, while others don’t.

Use some foil and a bowl of water to test how well foil will float, depending on its size and shape. 

29. The Science Behind Edible Glass

Have you ever eaten glass? Normally we wouldn’t recommend it, but this edible glass is super tasty, and pretty easy to make.

Like real glass is formed through melted grains of sand, this glass is made from grains of sugar. Melt it on a baking sheet, allow it to cool, and then get eating (or smashing).

30. Cleaning Coins Experiment

When you begin to think about how many people have held the coins in your purse at some point, it can make your skin crawl a little. Coins are super dirty.

Try this experiment to see what material can clean coins the best, from apple juice to catsup. You’ll be surprised at how shiny your cents will be afterward!

31. Red Cabbage pH Indicator

Most people will remember learning about pH levels in school, and how much fun it was, seeing all the colors of the rainbow.

Blend up some red cabbage with water, and mix with everyday items – such as lemon juice and soda – to test their pH levels based on which color the liquid becomes.

32. Skittles Science Fair Project

Many of you may have seen this experiment through social media, with many people testing it out with their children at home.

This colorful project involves placing Skittles on a plate, and adding a couple of drops of water. Watch and see how the colors streak across each other.

33. Tooth Decay Egg Experiment

We all know that sugar is bad for our teeth, but how can you test that notion in a class of 6th graders? Well, by using some eggs!

Place hard-boiled eggs in separate containers filled with soda, energy drinks, orange juice, and milk, and wait to see how the eggs react to each liquid.

34. Science of Candy: Lightning in Your Mouth

Did you know that LifeSaver candy can glow in the dark? Yes , really! This is a great experiment to teach kids how friction can cause electricity, even in your mouth.

Go into a dark room, and chew on some wintergreen-flavored LifeSavers with your mouth open. Everyone around you will be able to see the lightning going off around your teeth.

35. Why Does Popping Candy Pop?

As we promised, here is an experiment that will teach children why popping candy does what it does!

There are tiny pockets of gas inside popping candy, which are released when exposed to liquid. Test this out by adding the candy to different kinds of liquids, from water to oil.

36. Which Fruits Rot the Fastest?

This is a pretty gross experiment, but it is still a fascinating one that the children are going to love. For this project, you will need to work with some rotting fruit.

Place different fruits in separate bowls, and observe how they decompose over the course of 14 days. Take note of what happens as they rot.

37. What Light or Heat Conditions are Favorable to Insects?

Have you ever been on your phone in a dark room, and a moth landed on the screen? Insects seem to be attracted to light… or, are they attracted to the heat of your phone?

Use this experiment to find out what conditions attract insects. You may want to avoid this one if you don’t like bugs, though.

38. Paper Towel Experiment

Paper towels are one of the world’s most underrated inventions, in our opinion. It really is fascinating how they can absorb so much liquid before breaking.

Is it really worth spending more money on a more expensive brand of paper towel? Test the theory by using different kinds of paper towels to clean up water, and see which works best.

39. Mini Marshmallow Launcher

This experiment can get a little messy, especially when kids are involved, so be warned before trying it…

Basically, this experiment is all about elasticity. You create a launcher using a balloon and a pool noodle, and use it to launch mini marshmallows around the room!

40. A Simple Ant Experiment

This is another messy experiment that will teach children more about creepy crawlies, and what they like to eat.

Find some ants, and use different kinds of food to lure them in. Take notes of which kind of food ants prefer to eat, and which ones they don’t like.

41. How to Make a Teleidoscope

Kaleidoscopes are truly magical contraptions, no matter what age you are. Did you know how easy it is to make your own at home?

This guide will teach you how to make your own teleidoscope ( a kaleidoscope without an end). All you need is some reflective sheets, colored paper, and a cardboard tube.

42. St Patrick’s Day Fizzing Pot Experiment

This experiment is kind of like those baking soda volcano experiments that we all made in school, but with an Irish twist.

Grab some small, black plastic pots, and add some baking soda, vinegar, and green food coloring inside. Give it a stir, and see what happens.

6th Grade Science Fair Projects

6th grade science fair projects can be fun as well as educational. The key to finding a good project idea is to pick one that can be completed in time, uses materials you can actually find, and incorporates the scientific method . You can turn any science project into a science fair project by finding one factor you can change (the independent variable ) and measuring its effect on another factor (the dependent variable ). Either predict what you expect to happen or form a hypothesis , record the data, determine whether it upholds the prediction, and report your findings.

Here is a collection of 6th grade science fair project ideas. The projects include chemistry, biology, physics, geology, weather, environmental science, and engineering.

Grow Geodes in Egg Shells

Geodes form when minerals crystallize from water trickling into holes within rocks. While natural geodes take millions of years to form, you can make your own geode in a few hours or days. Use an eggshell as your “rock” and crystallize salt, sugar, borax, or Epsom salts.

Make It an Experiment: Turn this cool project into a science fair experiment by predicting how temperature affects crystal formation. You can explore the effect of rate of cooling on crystallization by insulating the growing geode with a hot water bath, leaving it at room temperature, and refrigerating it.

Build a Structure to Withstand an Earthquake

Explore the principle engineers use to construct buildings to withstand seismic events like earthquakes. Use styrofoam plates as the “ground” and make buildings using craft sticks. Join the craft sticks to each other using mini-marshmallows. Use a sharp pencil to poke holes in the bottom of the plate to insert craft stick supports. These will be the building’s foundation. When you have finished construction, shake the plate from side to side to simulate an earthquake.

Make It an Experiment: What type of structure survives the simulate earthquake the best? Is it rigid or flexible. You can perform a similar simulation by constructing a structure meant to withstand a hurricane. Use a fan as the wind and examine how the type of wall affects the building’s stability.

Control the Rate of a Color Change Reaction

Many color change chemical reaction are clock reactions. What this means is that if you mix the same amounts of chemicals under the same conditions, the color change occurs after the same time interval (like clockwork). The blue bottle reaction and vanishing valentine are excellent clock reactions for 6th grade science projects.

Make It an Experiment: Predict whether changing the concentration of the starting chemicals or the temperature of the liquids will increase or decrease the speed of the color change. Perform the experiment, record the results, and see if you can explain them.

Turn Milk Into Plastic

Many common plastics come from petroleum, but you can make a plastic from milk . Basically, all you do is curdle the milk . Heat 1/2 cup of milk or heavy cream over low to medium heat until it simmers. Stir in lemon juice or vinegar until the mixture starts to thicken. Remove the pot from heat. When the liquid has cooled, rinse the curds with water. These curds are a natural casein polymer. You’ve made homemade plastic!

Make It a Science Experiment: Your experiment might explore the properties of this plastic, including how far it will stretch, how much weight it can hold, and whether it can be used as a modeling compound. Another option is to compare the amount of plastic you get from cow’s milk compared to goat milk or sheep milk. Do you get the same amount of plastic from cream as from milk?

Explore the Pigments in Leaves

Most leaves look green from chlorophyll, but actually contain several different pigments. In the autumn, plants make less chlorophyll, so you can see the other colors. You can use paper chromatography to see pigments in leaves. To do this, grind leaves to break open their cells (a blender works well), place them in a small jar, add just enough alcohol to cover the leaves, and insert a long strip of coffee filter paper into the jar. You want one end of the paper strip in the leaf mixture and the other end extending up and outside of the jar. As liquid moves up the paper, it pulls pigment molecules along. Smaller molecules move faster, while larger molecules move slower. Over time, this separates the colors.

Make It an Experiment: See if you can identify which pigments the leaves contain based on their colors. Gather leaves from a single plant from multiple seasons. Compare the pigments from spring, summer, and autumn. Can you tell the season by the pigments present in the leaves?

See the Iron in Breakfast Cereal

Use a magnet to separate the iron from breakfast cereal so you can actually see it. To do this, pour one cup of crushed cereal into a zipper-lock bag and fill the bag half full of warm water. Shake the bag to mix the contents and allow at least 20 minutes for the flakes to dissolve. Place a strong magnet against the side of the bag and slosh the contents around so the magnet can capture the iron. Finally, keep the magnet up against the side of the bag but tilt the bag so you can see the iron. It will appear as tiny black specks.

Make It an Experiment: Compare the iron in different cereals. Do all cereals contain about the same amount of iron? Does it look the same in every product?

Use Eggs to See Which Drinks Stain Teeth

Tooth enamel is the mineral hydroxyapatite (hydrated calcium phosphate), while egg shell is calcium carbonate. Egg shell is more porous than tooth enamel, so it stains more quickly. Soak eggs in tea, coffee, soda, and other liquids to determine which ones stain teeth. Common drinks also contain acids in addition to pigments, so some drinks dissolve egg shell (and teeth). Can you identify them?

Make It an Experiment: After staining the eggs, predict which methods work to remove the stains. Test these methods and see if you can discover how they work.

Use Household Chemicals to Clean Old Coins

Learn about oxidation, which includes tarnish, patina, and rust. Explore the cleaning power of common household chemicals. Soak discolored coins in soap, laundry detergent, lemon juice, salt water, soda, ketchup, vinegar, salsa, or any other products you like. After soaking, remove the coins and rinse them to see which ones clean the coins the best.

Make It an Experiment: Part of making this project an experiment is predicting which chemicals make the best cleaners. Also, you’ll have to determine the best amount of time to soak the coins. You can compare how well these chemicals work on different types of coins (like pennies, quarters, and nickels). Do you think the metal composition of the coin affects how well the cleaners work?

Make a Graphite Circuit

Graphite is a form of carbon that conducts electricity. You can draw a line of graphite using a pencil to make a simple circuit . Use a battery with both terminals on top (like a 9V). Turn the battery upside down on the paper and draw heavy pencil lines whether the terminal rest (don’t connect these lines!). Take an LED and bend the wires apart so they can rest separate on the paper. Rest each wire on a pencil dot. Complete the circuit by drawing lines to connect one terminal of the battery to one end of the LED light and the other end of the battery to the other LED wire.

Make It an Experiment: Explore whether the length or thickness of the line affects how brightly the LED glows. You can make a circuit using aluminum foil strips instead of graphite, too.

See Whether Food Color Affects Its Flavor

Examine the effect of color on perceived taste by coloring different drinks with food coloring and asking subjects to describe their flavor.

Make It an Experiment: Compare the flavor of colored and uncolored versions of the same drinks. Start with drinks that don’t have any color so subjects are less likely to guess the drink flavor in advance.

Test Whether Temperature Affects Maximum Balloon Size

Start with a package of party balloons (ideally all the same color and brand). Part of the fun of this science fair project is planning how you can test the effect of temperature on balloon size. Consider your options in terms of indoor versus outdoor weather and access to freezers and saunas. You need to blow up a balloon and measure its maximum size before it pops. Either get a friend to help with the measurement or fix a measuring tape to the wall and keep an eye on the numbers.

Make It an Experiment: You are well on your way to making an experiment if you make a prediction about whether temperature affects maximum balloon size and design a method to test the hypothesis. Can you propose an explanation for your results?

See If All Crayon Colors Melt at the Same Temperature

Crayons consist of wax, colorants, and sometimes fillers. See whether all crayons melt at the same temperature. You’ll need a bunch of different colors of crayons, a thermometer, and a way to melt them. Fortunately, wax melts at a lower temperature than water boils, so you can slowly heat water, watch for melting, and record the temperature. Another method is to place crayons (not-touching) on a sheet of wax paper on a cookie sheet, heat an oven to 350 ºF (or any temperature, really), and record which crayons melt first.

Make It an Experiment: Make predictions and answer questions. Do you get the same results with different brands of crayons? Do old crayons have the same melting point as new crayons? Watch for control variables , like the size of the crayons and whether you pre-heated the oven.

Make Lightning in Your Mouth

To make lightning in your mouth, crunch a Lifesaver Wint-O-Green or Pep-O-Mint candy in your mouth in front of a mirror in a dark room. Saliva can ruin the effect, so you might want to dry out your mouth with a paper towel first. The blue sparks that resemble lightning are due to an effect called triboluminescence . The sugar in the candy releases electrical energy when the crystals are compressed. The tiny charges attract nitrogen in the air, making miniature lightning bolts. Make It an Experiment: Get different types of hard candies and predict whether they will produce sparks in the dark. See if you can explain why some candies work better than others.

It’s that time of year again—when students are gearing up for the science fair. And if you’re looking for some inspiration, look no further!

In this blog post, we will explore 18 mind-blowing ideas for class 6 science projects that will get those gears turning. So without further ado, let’s get started! 

• Pull an egg into the bottle
• Design a Biodome
• Generate Electricity with Potato
• Dissect owl pellet
• Construct a Pair of Model Lungs
• Build Heart Pump Model
• Learn inertia with fidget spinner
• Perform Archimedes squeeze
• Build a mobile stand
•  Turn Milk into Plastic
• Change liquid color instantly
• Assemble Steady hand game
• Launch Two-Stage Rocket
• Send Water Down with String
•  Make Naked Eggs
• Assemble a Simple Motor
• Build Paper Plane Launcher
• Ferris Wheel

Here’s a fun science project that you can do at home! All you need is: 

• A hard-boiled egg
• A glass bottle with a narrow neck.

Place the egg on top of the bottle opening and gently apply pressure to push it down into the bottle. The egg will start to descend into the bottle, but then it will get stuck.

Now, use your mouth to create suction on the bottle. This will cause the air pressure inside the bottle to decrease, which will allow the egg to be pulled further down into the bottle.

Keep applying suction until the egg is completely inside the bottle. Now wasn’t that cool?

Planning to design a biodome for class 6 science project is a great way to learn about ecosystems and the environment. By creating a miniature version of a natural ecosystem, you can observe how different plants and animals interact with each other.

This project is perfect for any science class , including biology, ecology, and Earth science. With careful planning, you can create a detailed and fascinating project that will teach you about ecosystems while also providing a fun way to learn about the natural world.

Potatoes are a great source of energy and can be used to generate electricity. There are many ways to do this, but one of the most popular is to use a potato battery. This is a simple science project that anyone can do at home with a few inexpensive materials.

To make a potato battery, you will need:

• Two metal screws
• One alligator clip lead
• One piece of copper wire
• One zinc nail

Start by poking the two metal screws into opposite ends of the potato. Then, take the alligator clip lead and attach it to one of the screws. Next, take the copper wire and wrap it around the other screw. Finally, take the zinc nail and insert it into the potato so that it touches the copper wire.

That’s it! Your potato battery is now complete. To test your battery, simply touch the free end of the alligator clip lead to the zinc nail. 

Owls are amazing predators that can take down prey much larger than themselves. One of the ways they do this is by swallowing their prey whole and then regurgitating the indigestible parts in the form of a pellet. These pellets are great for science projects because they contain all the bones and fur of the owl’s prey.

To dissect an owl pellet, start by breaking it open with your hands or a tool like a screwdriver. Once you have access to the contents, sort through them to find any bones or teeth. These can be studied to identify what kind of animal the owl ate. The fur can also be examined to determine what kind of animal it came from.

To construct a pair of model lungs, you will need:

• 2 clear plastic soda bottles
• A pen or marker
• Construction paper

Cut the bottom off of both soda bottles. On one bottle, use the pen or marker to draw a line around the middle. Cut along this line. Repeat step 2 on the other bottle. Now, take one of the halves of a bottle without a top and tape a straw to the side. This will be your “inhale” tube. Do the same with the other half of bottle, but tape the straw to the opposite side – this will be your “exhale” tube.

Place both halves back together, matching up the sides without straws. Tape them together at the seam. Cut out two lung shapes from construction paper using scissors. Glue these onto either side of your model lungs (opposite of where the tubes are taped on).

To build a heart pump model, you will need the following materials:

• 1 empty plastic water bottle
• 1 small balloon

Cut the bottom off of the plastic water bottle. Stretch the small balloon over the opening of the bottle. Secure it in place with tape. Use the marker to draw a heart on the balloon. Cut a small hole in the center of the heart. Blow up the balloon through the hole until it is about half full.

Tie off the end of the balloon to keep the air inside. Turn the bottle upside down and hold it in one hand. With your other hand, gently squeeze and release the balloon to make the “heart” pump!

Fidget spinners are a great way to help kids learn about inertia ! When you spin a fidget spinner, you are actually using inertia to keep it going. The more mass an object has, the more inertia it has. That’s why it’s important to use a heavier fidget spinner if you want it to spin for a long time.

There are lots of other fun science experiments you can do with fidget spinners too! Try testing how long different types of fidget spinners will spin for, or see how far you can make one fly when you throw it. There are endless possibilities for fun and learning with fidget spinners!

If you want to amaze your classmates with a truly mind-blowing science project, try the Archimedes squeeze. This simple experiment demonstrates the power of air pressure. All you need is a large container of water and a small object that will float in water.

To start, fill the container with water and place the object floating on top. Then, take a deep breath and blow into the container while keeping your mouth open wide. The object should be forced down into the water by the force of your breath.

Now take your thumb and finger and make a seal around the neck of the container. Then, quickly remove your hand from the neck of the container. The seal should hold and the object should be forced up out of the water and into the air!

The Archimedes squeeze is a great way to amaze your friends and classmates with the power of air pressure. Try it today!

When it comes to building a mobile stand, there are a few things you’ll need to take into account. First, you’ll need to decide what type of stand you want to build. There are two main types of mobile stands: those that sit on a table or desk, and those that can be mounted to a wall.

If you’re opting for a table or desk-based stand, you’ll have to make sure that the stand is stable and won’t tip over easily. You’ll also want to consider how easy it will be to move the stand around; something with wheels may be ideal in this case.

For a wall-mounted stand, you’ll have to make sure that the mount is secure and won’t come loose easily. You’ll also want to consider how easy it will be to access your phone while it’s mounted; something with a swing arm may be ideal. Once you’ve decided on the type of stand you want to build, gather your materials and get started!

To perform this class 6 science project, collect some milk from the grocery store. You will need about two cups.

Pour the milk into a saucepan and heat it over low heat until it becomes lukewarm. Do not let the milk boil. Next, add one tablespoon of vinegar to the milk and stir gently. Continue stirring until all the liquid has turned into small clumps.

Strain the curds from the whey by lining a colander with cheesecloth and place it over a bowl. Pour the curdled milk into the colander and allow it to drain for about an hour. The whey will drip into the bowl below while the curds remain in the colander.

Then, transfer the curds to a clean piece of cheesecloth and squeeze out any remaining liquid. You should now have a ball of wet, white cheese in your cheesecloth.

Congratulations, you have just made ricotta cheese! To turn ricotta cheese into plastic, remove the water from the cheese. For this, place the cheesecloth bundle in a colander and set it over a bowl. Put a lid on the colander and place it in the fridge. Let it sit overnight so that the water can drain out of the cheese.

In the morning, you should have a dry, crumbly ricotta cheese. Congratulations, you’ve made plastic! 

If you want to change the color of a liquid instantly, all you need is: 

• Some food coloring
• A clear container. 

Fill the container with the liquid you would like to change, then add a few drops of food coloring. The more food coloring you add, the darker the color will be. Stir the mixture until the color is evenly distributed, then enjoy your new creation!

Assuming you have all the necessary materials, assembling a steady hand game is a relatively simple process.

The first step is to put the baseplate on a flat surface. Then, take the two metal rods and insert them into the holes on either side of the baseplate.

Next, take the plastic ball and place it on top of the metal rods. Finally, put the cover over the ball and secure it in place with the screws. 

For this class 6 science project, you will need:

• Two identical rockets
• A launchpad and

Place the rockets on the launchpad side by side. Fill one rocket with fuel and ignite it.

As the first rocket takes off, simultaneously launch the second rocket. Observe and record the results of your experiment .

If you’re looking for a really fun and unique science project, try sending water down with string! This project is perfect for kids of all ages and can be done with materials you probably already have around the house.

Here’s what you’ll need:

• A clear plastic cup
• A piece of string or yarn

To get started, fill your cup with water and tie the string around the top. Make sure the string is long enough that it hangs over the edge of the cup. Next, use the tape to secure the string in place. Now, carefully turn the cup upside down and watch as the water slowly flows down the string!

This project is a great way to learn about gravity and how it affects liquids. Plus, it’s just plain fun to watch!

You can make a naked egg by removing the shell without breaking the egg. It’s a neat science trick that you can do at home with just a few supplies.

Here’s what you’ll need:

• 1/2 cup white vinegar
• 1/2 cup water
• A glass or container that the egg can fit in snugly

Start by putting the egg in the vinegar and water solution. Make sure that the entire egg is covered by the liquid. Let the egg sit in the solution for 24 hours. 

After 24 hours, remove the egg from the solution and Rinse it off with water. Gently rub the egg to remove any leftover bits of shell. The egg is now naked! You can try blowing it up like a balloon, or bouncing it on the floor (it won’t break!).

You will need:

• A small DC motor
• One AA battery
• A small piece of cardboard
• A thumbtack or pushpin
• Some insulated wire (about 18 inches)
• Tape (any kind will do)

Begin by taping the AA battery to the piece of cardboard. Then, use the thumbtack or pushpin to make a hole in the top of the battery. Cut a small slit in the cardboard, next to the hole you just made. This is where your wires will go.

Strip about ½ inch of insulation off each end of your wire. Feed one end of the wire through the slit in the cardboard and twist it around the positive (longer) lead of the motor. 

Do the same with the other end of the wire, but twist it around the negative (shorter) lead of the motor instead. Finally, put a drop of glue or some tape over each connection to keep them from slipping apart.

That’s it! When you connect your battery to the leads on your motor, it should spin!

To build a paper plane launcher, you will need:

• A popsicle stick
• A rubber band
• A paperclip

First, take the popsicle stick and tape the rubber band to it. Then, take the paperclip and bend it so that it forms a hook. Tape the paperclip to the other end of the popsicle stick. Your paper plane launcher is now complete!

To use it, simply put a paper plane on the hook and pull back on the rubber band. Let go and watch your plane fly!

If you’re looking for an unforgettable science project, why not try building a Ferris wheel? This project is perfect for budding engineers of all ages. Plus, it’s a great way to learn about physics and how energy can be used to create motion.

• A large piece of cardboard
• A ruler or measuring tape
• Glue or tape
• String or yarn
• A small weight (a paperclip or coin will work)

Cut out a large circle from the cardboard. This will be the base of your Ferris wheel. Using the ruler or measuring tape, mark out eight evenly spaced points around the edge of the circle. These will be the locations for your Ferris wheel supports. 

Cut eight strips of cardboard, each about 4 inches long. Glue or tape each support strip to the base at the marked points. Make sure that the supports are standing up straight. 

Tie string around each support, about 2 inches from the top. The string should be long enough to reach the ground when your Ferris wheel is complete. 6. Tie the other end of each string to a small weight (a paperclip or coin). This will help keep your Ferris wheel upright when it’s spinning.

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.

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.

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.

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.

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.

Interesting Science Experiments for Class 6

• Updated on  
• Sep 15, 2022

Fire, smoke, coughing and spiked hair are not the only consequences that one may get by performing an intensive science experiment especially one with chemicals. You must have seen in Dexter’s Laboratory that mere mixing of two chemicals or substances can result in a blast, but that’s a rather dramatic representation, to begin with! There are various scientific experiments that you can perform with simple household products and understand concepts actually earlier took years to be ideated. So, fetch your lab coat as we bring you a list of 10 interesting science experiments for class 6 that you can perform at your home. 

This Blog Includes:

Bouncing egg experiment , light travels only in a straight path , different sizes of shadows , burning of paper is a chemical change, saturated solution , difference between like and unlike poles of a magnet, transportation of water in plants , the stem of a plant always grows upward, difference between transparent and opaque materials, oxygen is necessary for fire , turning a potato into a battery, study of sound waves using a spoon, let’s put an egg in a bottle, experiment using naked eggs, magic water balls, dry ice boat, make a hot air balloon, build a wind vane.

We know how fragile eggs are, even a slight bump or jerk happens to crack the shell of the egg. Through this simple science experiment for class 6, we will tell you how you can make an egg bouncy. To start, you will need an egg and a bowl filled with white vinegar. Immerse the egg in the bowl and then leave it at room temperature for around 3-4 days. Later on, you will see that the egg has become translucent in its appearance and is no more fragile than it used to be earlier. 

This science experiment for class 6th will explain to you how the light only travels in a straight path. It is not feasible to determine the path of light in the day to day activities but through this experiment, we can learn about it quickly. For this, you need to light a candle and please two cardboards adjacent to it, one behind the other. Make one hole in both the cardboards exactly at a place from where you can see the flame of the candle. Turn off the lights and you will be able to see the rays emerging from the candle will go straight into those holes.

We know that all the opaque objects have shadows. You must also come across that we see various types of shadows in different lightings. Have you ever thought why a certain shadow is a bigger or any other one is smaller? For this Class 6 science experiment, take a torch and a circular piece of cardboard and stand in front of a wall.

Place a circular piece closer to the wall and direct the light of the torch towards it and then move the piece of the cardboard closer to the torch. You will see in the former case the shadow of the cardboard is almost equal to its original size but in the latter case when the cardboard is closer to torch the shadow is enlarged. 

In the sixth standard students are memorized with various types of changes that take place around us. Out of all the science experiments for class 6 on types of changes, through this one will understand how the simple act of burning a paper is a chemical change. Take a normal paper and light a matchstick to burn it. Make sure that you take the help of an adult while burning the paper to ensure all the required precautions. Note that once the paper is completely burnt then only ashes will be left behind. Since the burning of paper has resulted in the formation of a new substance, it is classified into the category of chemical change. 

We know that water is known as a universal solvent. It can easily absorb the majority of soluble substances around us. In this science experiment for class 6, we will begin by taking a glass full of water and adding a spoonful of sugar in it. Mix sugar thoroughly and keep on adding one by one spoon after mixing. After some time you will notice that no more sugar is getting dissolved in water. This signifies that water has reached its saturation point. 

While playing the magnet you might have experienced that, often magnets do not get attracted if we try to do so. This is because, just as our planet earth, magnets also have North and South poles. So, for our next science experiment for class 6, let’s begin by taking two bar magnets and keep them facing like poles that are N-N or S-S, you will see that like poles do not attract each other as they are repulsive. But when the same magnets are kept facing unlike poles together N-S, they will immediately get attracted to each other. 

Plants are also living organisms, thus, they possess a constant need for food as well as water. We know that plants are autotrophs and make their own food, but do you know how transport water for the process of photosynthesis ? To understand this we will take a stem of a plant and cut it. In a bowl, we will take some coloured water, in which we will place that stem for about 2-3 days. You will notice that after a few days the colour of the stem and leaves matches the colour of the water. This science experiment for class 6 shows that plants transport their water with the help of their stem. 

Roots and stem are considered to be fundamental parts of the plant. Do you know that roots and stems grow in a particular direction? You will come across various science experiments for class 6 which will easily explain this to you. Let us consider a simple one, take any flower pot and place it upside down in sunlight for at least one week. After one week or 10 days, you will see that in spite of the downward direction placement the stem of the plant has changed its direction and has started to grow upwards. 

We are surrounded by various sorts of materials which either allow light to pass through them or don’t. Among all the science experiments for class 6, this is the most interesting one which will help us bifurcate materials into transparent and opaque. First, we will light up a candle, then take a glass jar and try to see that candle through it. You will be able to clearly see the candle as glass is a transparent material. Now, take a wood log and try to see the candle through it. You will not be able to see it because wood is an Opaque material. 

Lighting a candle or simply lighting up anything is a common phenomenon of daily life. According to you what is the essential thing required to light a fire? Don’t know the answer? Let’s explore it through this science experiment for class 6. Begin by lighting up two candles. Place a glass jar on top of a candle that covers it entirely. After a while, you will notice that the flame of the candle covered with a glass jar will go off. This is because, in that covered jar, the amount of oxygen is limited and eventually gets exhausted resulting in the going off of the flame. Thus, the most necessary thing for lighting a fire in the presence of oxygen. 

Unique Fact: We all love to blow out candles on our birthdays. Since oxygen is essential for the existence of fire, then how come the candles are blown out by a simple puff of air? This happens because the air that we blow out from our mouth contains carbon dioxide which acts as a fire extinguisher. 

Wow! This seems to be magic. Isn’t it? Well, guess what it is just simple science. With this class 6 experiment, students will be able to learn the use of the potassium which is present in the potatoes to conduct energy which will turn potatoes into batteries. For this class 6 experiment, you require potatoes, good quality copper wires, galvanised nails, copper nails, and 1 LED bulb or light. The experiment is an oldie but still considered to be a goodie. If you are not having potatoes at home, then the experiment can even be performed using lemons or other high-potassium fruits and vegetables. 

This class 6 experiment will help you study and learn about how vibrations create the sound as well as the role of conductors. You will only be needing a few common things like a ruler (preferably a wooden or a plastic one), metal spoons of two different sizes, a long piece of yarn or string. First of all, create a loop in the middle of the yarn or the string. Now insert the end of the spoon into this loop. Pull each end of the yarn and tie a knot such that the spoon hangs in the. Now take each string and start wrapping them around your forefinger in both the hands. Now place the strings against your ears (near the ears) such that the spoon must be hanging below or near your waist and both the ends of the yarn or string must be placed near your ears. Now ask someone to gently hit the spoon with a ruler.

This is yet another class 6 experiment which is a classic again but never fails to delight the students and kids. You will only be needing a few things to perform this experiment namely: a hard-boiled egg (peeled), a glass bottle having a mouth smaller than the egg, matches or lighter and paper strips. Cut a long paper strip and then light the piece of the paper strip, taking the help of an adult. Quickly put this paper strip in the bottle while it’s burning and quickly place the egg on top of the mouth of the glass bottle and observe the egg popping inside the glass bottle just like that. 

Well, don’t just throw away those naked or the shell-less eggs that you have just discovered using the above-mentioned class 6 experiment. Submerge those naked eggs into corn syrup and water, in separate vessels or glasses. Make sure that the eggs are completely submerged. You will notice that the eggs tend to shrink or grow depending upon the liquid they are placed into. 

A simple science experiment for Class 6 students, the Magic Water Balls experiment needs a glass container, a cup of water balls and a bottle of water. Take the container, put it on paper with any text like ‘Magic Water Balls’ written on it and then fill the container with the water. As the balls start swimming into the water, you will start to see the text which happens as the refractive index of water matches that of the water balls and thus the text is visible!

The Dry Ice Boat experiment is another fun one to do at home for Class 6 students. Here are the requirements for the Dry Ice Boat experiment:

• A wide tray
• Some food colors
• One scissor
• Water to fill up the tray
• Safety gloves and glasses

Start with wearing the gloves and glasses first and then fill the tray with water. Then, take some food colors and add them to the water to make it darker. Now, ask an adult to break the dry ice using a hammer. Now, add the little pieces of dry ice in the water and you will see them revolving in circles. You can further extend the experiment by cutting a pipette into two pieces and then adding some ice to the one-piece and putting them in the water (See video for reference).

As one of the best science experiments for Class 6, making a hot air balloon at home can be a magical yet tricky task. For this, you will just need a tape, some straws, a scissor and a big plastic bag for first making the balloon’s structure and then take some small birthday candles and a few square-cut size of aluminum foil. Ask an adult to help you make the balloon as in the video and then further attached the candles to the foil to make the base.

A wind vane is a popular science project amongst school students and can be a fun DIY thing you can make for your room too! It is one of the best science experiments for Class 6 especially for those who don’t like working too long in the chemistry lab! So, let’s start with the requirements first. You will need the following things to build a wind vane:

• 2 paper plates
• Plastic straw
• A cardboard
• Some straight pins
• A pencil with an eraser on the top

Start with writing directions on the back of the paper plates using a compass and you can also decorate them with fun colours. Then, cut out the shapes of arrows from the cardboard and take a straw, cut its edges slightly to stick the direction arrows on both sides (refer to the video). Then, stick a pin right in the middle of the straw, and then stick it to the top of the pencil (on the eraser). Poke the pencil through your paper plate and put it in the modelling clay. Take another paper plate and put it under the clay and paste the two plates together. Now, your wind vane is ready, position it using a compass and blow on it to see how it works! Have fun!
