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

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

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

This science project examines the history of earthquakes and what we can do to prevent future disasters.

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

Find out whether matching resonant frequencies can cause objects to shatter.

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.

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.

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

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.
