Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

Take this "paper plate snack test" with your child for a hands-on lesson in making healthier choices to teach your child about what's in his food.

This taste buds science experiment demonstrates how strongly our sense of smell controls what we taste.

Show your kids the power of baking powder by conducting a simple experiment. Make four batches of cornbread, all identical except for one thing: baking powder!

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.

Wool can absorb 1/3 of its weight in water, while still keeping the body warm. She can test this theory by performing a scientific sock comparison!

In this fun science fair project idea learn about universal solvents and solutes and find out the solubility of several common liquid substances.

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.

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

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

This easy aerodynamics activity is a simple way to introduce kids to the scientific method.

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.

How sensitive is your skin? Here's a fourth grade science experiment that lets your child figure it out.

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!

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.

Get your hands on a concoction that breaks the rules about what's a solid and what's a liquid.

Amaze your kids by separating a salt and pepper mixture using an "electric spoon" charged with wool.

This surprisingly good glue recipe comes from common kitchen items.

Encourage your child to think outside the bathtub by making her very own handmade soaps! Perfect as a present, a decoration, or just to pamper herself.

Let your young scientist explore a brave new world of sound with an experiment that just requires a handful of common household items.

This 4th of July, explore fourth grade science and make some safe fireworks in your own backyard using soda pop!

Make your own marshmallows and mix up some very interesting third grade chemistry lessons while you're at it!

Before your treat your child (and yourself!) to a yummy snack, help her learn a little about Sir Isaac Newton's First Law of Motion!

Inspire your child to put on her engineer hat for the day, as she builds her very own, double-decker bridge.

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

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

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

Teach your child how butter is created by shaking up cream the old-fashioned way.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

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