Explore the wave-particle duality of light! Learn how light can behave as both a wave and a particle in this cool physics science fair project idea for kids.

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

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

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