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

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.

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.

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