Try this experiment to give your curious kid a more "solid" understanding of how temperature affects the states of matter.

Make meringues with your first grader and see how states of matter can transform before your very eyes. Here's how:

This kindergarten science activity will help her explore the changing states of matter which transform an egg from raw to soft to hard-boiled.

Let your fourth grade chef mix up butter and sugar with scientific principles about different states of matter, and get delicious toffee, too.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

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.

This experiment investigates whether there are certain sounds that affect men and women differently

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

Teach your first grade scientist the difference between liquids and solids using maple syrup.

Experiment with magnetism in this 8th grade science activity in which your child will create a working compass using a steel needle, magnet, and jar.

Do this experiment to help your first grader understand how salt can be removed from salt water. All it takes are a few household materials.

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

Here's a fun activity to reinforce the physics concept of stored energy for your middle schooler.

Here is a quick experiment you can conduct at the playground to introduce or reinforce the concept of Newton's First Law, The Law of Inertia.

This potato cannon activity teaches your middle schooler about the principle of Boyle's Law. Make a potato cannon and have a blast learning about science.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

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

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

Have your child try this classic experiment that demonstrates circular motion using a bucket and rope. Be careful, you might get soaked!

In this fun science fair project idea learn the difference between additive and subtractive color and why they are handled differently.

Looking for a way to help your teen explore the fun side of physics? How about a round of Saturday morning cartoons?

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.
