The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

This science fair project idea produces sounds by creating vibrations using different objects.

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

This science fair project idea demonstrates sonar mapping of the ocean floor.

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

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

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

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

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 project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

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.

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

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

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.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

This experiment investigates whether there are certain sounds that affect men and women differently

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