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.

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

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.

Learn with makes water molecules work with this fun and easy science activity!

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.

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

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.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

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