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.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

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

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

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

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

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

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.
