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

Explore concepts in current and coltage with these Van de Graaff generator experiments.

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

In this cool science fair project, kids apply basic algebra to learn how to make a PVC pipe instrument while exploring concepts like frequency and resonance.

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.
