This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

In this project students experiment with making music using only glasses of water.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

This project examines if computer screen and text color affect retention and if people subconsciously prefer combinations of colors that help their retention.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?
