10 Easy Science Experiments For Kids


Density. Polymers. Magnetism. No, we’re not developing a high school science curriculum! These are just a few of the scientific concepts the experiments below illustrate. Everyone can participate in these easy, top-rated science experiments for kids. You just may have a budding scientist on your hands!

1. Bouncy Rubber Egg Experiment (Ages 4-16)

Can you make a raw egg bounce? For the first of our easy science experiments, you can turn a raw egg into a bouncy “rubber” egg with just one household ingredient! Bonus: what happens when you use a smaller egg, or add food coloring? Watch to find out!

2. Liquid Density Experiment (Ages 5-16)

Density is a foundational concept in physics, which explains why boats float, rocks sink, and balloons fly away when you let them go! With just a few materials from home, you can conduct your own colorful density experiment, and see how this principle works firsthand. Check it out!

3. Instant Cloud Science Experiment (Ages 7-16)

Ever wonder how clouds work? Try this experiment at home to learn more about how real clouds work. For younger makers, we encourage parent supervision to help with the rubbing alcohol and popping of the cap.

4. Bouncy Ball (Ages 4-16)

Did you know you can make your own bouncy balls at home? You can with this project that’s also a quick chemistry exploration in polymers. You’ll be jumping for joy right alongside your super awesome bouncy balls at the end of this experiment.


5. Sink or Float Printable Experiment (Ages 3-6)

Teach children the scientific method–and experiment with buoyancy – with this easy printable! Guess which objects will sink or float… then test your hypotheses! Kids draw their predictions, so even preschoolers can try. To get kids outside, do this experiment after collecting objects on a nature walk.

6. Elephant Toothpaste Experiment (Ages 4-16)

Get outside and make your own volcano! With just a few household ingredients, create a (safe) explosion that looks like enough toothpaste for an elephant to brush with. (his project requires a grownup’s assistance, but all the items are safe to use.

7. Rainbow Milk Experiment (Ages 4-16)

Why do the colors burst? The secret is in the tiny drop of dish soap. Have you ever wondered why cleaning a dish with soap is so much more effective than using just water? You can try this yourself by smearing some oil onto two identical plates. Give yourself just 30 seconds each to clean one with just water, and the second with water and dish soap. The one you clean with only water will probably still feel very oily, while the one you washed with soap feels much cleaner.

8. Electromagnetic Train (Ages 9-16)

Did you know that electricity and magnetism are closely linked? In this project, experiment with the interplay between the two by building your own miniature electromagnetic train that zips down a track all by itself.

9. Magic Inflating Balloons (Ages 5-16)

Can you make a balloon inflate without using air? Sure you can! You just need to make carbon dioxide gas, which is easier than you think. When your vinegar and baking soda touch, get ready to watch the bubbly reaction!


10. What Soda Does to Teeth (Ages 5-9)

Is soda bad for your teeth? This simple-to-set-up experiment provides a clear answer.

BONUS: KiwiCo Fire Lab

How does fire work?  The KiwiCo Fire Lab chemistry kit contains everything you need to explore concepts such as combustion, oxidation, and capillary action.

  1. I cannot tell how much, of what, to do when, in the Volcano experiment just by watching the YouTube video. Can I get detailed instructions please?

    Thank you!


      1. Thanks😊 i like all the experiments . You had suggested me idea for science exhibition in my school. I know i will got good marks by trying these experiments. 🌋🚔 thanks again and have a nice day.

  2. Thank you sooo much for this! I was in desperate need of some ideas, and to be honest I am not a creative person! Thanks a million, really. Hopefully I’m getting 10 on 10 on this one 😉

  3. I liked the bouncy egg experiment the most. The soda experiment is the least favorite,because it has GROSS TEETH!!!!!!!!!!!!!!!!!!!!! but I liked the blog very much!


  4. My son is dying to try the electromagnetic train! So cool!!! Do you know the exact size of the magnets and dowel that we need to buy? Thanks so much!

  5. Thank you so much for the ideas.I really did enjoy them.I will do them all and I have more ideas because of this.I will use these.Thank you so much again.

  6. Thank you for sharing this wonderful blog, this blog is related to 10-easy-science-experiments-for-kids. we are learning from you and podsquad.

  7. I can’t do any of these for my science project because none of these are actually experiments. They are all demonstrations. The difference is that in experiments, you have to try to find what works, and in demonstrations, you can just follow a guideline. You could adapt these ideas into experiments, like what to change, and how to control it (controlled variables), but these are all demonstrations. Also, if you want to keep videos, then you can, but that would only be what happens when you get the experiment right, and could be a very good point to stop.

    Anyways, besides ^this^, I enjoyed seeing the cloud demonstration, but I won’t do it for my experiment because of my reasons said above.
