WHAT IT IS ABOUT

Discover how light transforms into colors

In this activity, the girls explore what light is and how it is formed by different electromagnetic waves. Through the observation of a prism or a compact disc, they discover how white light can be broken down into different colors, as happens in a rainbow. Then, they build a homemade spectroscope to investigate how this phenomenon works and learn to observe light in a different way.
