Here's a science experiment that gives your kids a chance to see how fire needs oxygen to burn, with a little math and writing practice thrown in.

How do mirrors work? What is light, and how does it travel? Explore light and reflection with your preschooler with these simple hands-on experiments.

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!

Got a young scientist at home? Try this project with him!Create your own molecule design with this home-made clay recipe and some toothpicks!

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!

Your child will do a fun science experiment using soap and pepper flakes to help understand the concepts of water molecules and the surface tension of water.

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

Chemistry is a blast with this backyard bomb made from a sandwich bag. All you need are ingredients from the pantry to create a satisfying, and safe, explosion.

How powerful is the reaction between baking soda and vinegar? Find out here!

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.

This awesome diffraction grating experiment puts high school students' applied math skills to the test by having them calculate the wavelength of laser light.

Here's a classic celery science experiment that uses celery and food coloring to demonstrate how plants absorb water.

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