Showing Results for hard

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

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

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

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

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

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.

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