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!

  • Visual aid of how to complete Bouncy Egg
    Bouncy Egg

    (Ages 5-16)

    Can you make an egg bounce? Try this simple chemistry experiment and see the shell of an egg dissolve! You'll be left with a surprise and a fun, bouncy egg. 

    Discover everything that eggs have to offer with Eggsperiments from the KiwiCo Store! Use the scientific method with a series of egg-based experiments that explore chemistry, physics, and biology.

  • Visual aid of how to complete Density Tower
    Density Tower

    (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!

    (Ages 5-16)

    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.

  • Visual aid of how to complete Sink or Float?
    Sink or Float?

    (Ages 3-8)

    Will your toy sink or float? This experiment is fun for all ages.

  • Get outside and make your own volcano! With just a few household ingredients, create an explosion that looks like enough toothpaste for an elephant to brush with. (This project requires a grownup’s assistance.)

  • Visual aid of how to complete Milk Swirl Experiment

    See how a drop of soap can create an explosion of color with this easy experiment!

  • Visual aid of how to complete What Soda Does to Teeth

    Why is soda bad for your teeth? My kids keep asking why they can't have more soda. The tooth fairy was kind enough to lend us some baby teeth for us to experiment with, and we got some very interesting results.

Get inspired!
