Sun tanning has a bad rap right now. Use a personal ultraviolet monitor to measure the UV index to prevent getting a sunburn. With this science fair project you will create a chart showing the UV ray measurement at different times of the...

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all...

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...

Read about the visible light spectrum and learn the frequencies and wavelengths for each of the primary and secondary colors.
