The goal of this project is to measure the effectiveness of different sunscreen products for blocking ultraviolet-A (UVB) and ultraviolet-B (UVB) rays from sunlight. This project shows you how to use a UV detector to measure rays of light.

An interactive PowerPoint will be used to introduce the electromagnetic spectrum. Students use UV beads to observe changes caused by the sun's rays and evaluate sunscreen effectiveness. Harmful effects of UV exposure will be described...
