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.

What is condensation? Little mad scientists will learn about condensation, states of matter, and air pressure by conducting this cool science experiment.

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

To help your child learn how to use a thermometer, try this temperature collecting activity at home.

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.

In this plant habitats activity, children play the role of an ecologist and take surveys of different areas to discover the best habitat for dandelions.

This experiment examines whether storing your orange juice at different temperatures affects its acidity.

Science fair project that determines whether cooling eggs helps them be peeled more easily. Compare the time it took to peel each egg.

This craft is an excellent way to learn about African-American history, and it also provides fine motor practice.

This science fair project idea determines the probability of a coin landing heads or tails.

Do you love to make Jell-O? Find out in this science fair project idea if it is possible to make Jell-O with just warm water.

Science fair project which evaluates different athletic shoes in order to find out whether any of them affect a person's ability to run.

What chromosome combinations determine a fetus gender? Use probability to think about whether a sperm and ovum will create a male or female in this project.

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

In this activity, your child will make her own "quicksand" to better understand how a substance can be both fluid and solid at the same time.

Encourage a group of third graders to play this fun game of Whistle Hide-and-Seek as a warm-up to get them prepared for finding a "lost" camper.

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

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

Kids conduct a simple science experiment to see if seeds can grow without soil in this simple kindergarten science activity.

In this activity, your child will transform an egg into a glowing, bouncy "ball" that they can play with.

In this experiment you observe and determine how well your cat uses his whiskers to navigate through a maze.

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

In this science fair project, students will try to discover if test subjects can detect the presence of Monosodium Glutumate (MSG) in food.

This kinesthetic learning activity will help your fourth grader get a firm grasp on the immensity of the solar system.

You don't need to head to the Arctic to experiment with life in an igloo. Learners can build their own ice igloo at home from water and empty milk containers.

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.
