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.

If your fourth grader is obsessed with all things glow-in-the-dark, then here's an activity that will really light up her imagination!

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.

Have your child build his own mini waterfall, and help him develop his planning, problem solving, and architectural skills.

This science fair project idea experiments with spinning color wheels and optical illusions.
