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

In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

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.
