Make water and clay play a little more scientific with this hands-on experiment that teaches displacement and shows how an object's shape affects its buoyancy.

Make your own helicopter using a paper clip and a sheet of paper. Hold the spinner up in the air, let it go, and watch it spin gracefully to the ground.

Has your kid noticed how much bigger the moon looks when it's low in the sky? Here's an activity you can do to show them that it's just an optical illusion.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

Children combine an acid and an alkaline substance to simulate a volcano eruption in this fun experiment.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

An home science experiment for older students that teaches about the science behind heat.

In this activity, you'll not only make your own bouncy balls at home, but your child will also learn how polymers are made.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.
