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.

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 fun science fair project idea learn about the multiple sources of radio waves and fin out how difficult it is to block them.

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

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

This science fair project idea produces varying pitches of sound.

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

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

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