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

The purpose of this science fair project is to build a basic radio.

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!

This science fair project idea produces varying pitches of sound.

Get your sense of humor ready for this fun science experiment that demonstrates the fundamental physics of air pressure.

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

Try the classic balloon-on-the-wall trick with your kid and watch static electricity in action.

Introduce your child to science with something they see everyday--their shadow!

Set your young chemist up for an afternoon of science-fueled magic with a deceptively simple activity starring baking soda and vinegar!

Bring the magic and mystery of the night sky to the light of day with this fun constellation art project!

Here's a science activity that lets a first grader use an empty dish detergent bottle to create his own fountain as he explores air pressure.

This simple "how to make a water wheel" activity makes physics come alive for your child by demonstrating how different kinds of energy work.

Children combine an acid and an alkaline substance to simulate a volcano eruption in this fun experiment.

Put your second grade scientist to work this Fourth of July with our colorful "liquid fireworks" project!

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

This classic children's game demonstrates how sound travels through air vs. through a solid.

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.

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.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Check out this mind-blowing experiment in which a hard-boiled egg will fit through an impossibly small opening with the help of only a few matches!

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.
