Make a DIY golf putter and design your own golf putting course in this 2nd-3rd grade arts and crafts/game activity.

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.

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

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

Delight your budding scientist with this cool physics magic trick and teach her some basic physics concepts while you're at it!

This science fair project idea produces varying pitches of sound.

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.
