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

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.
