Here is a large collection of simple science class activities for understanding the physics of light.

In this activity, students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...

This website has three different projects from which to choose on the topic of why the sky is blue. Also, you can scroll up to learn more about why the sky is blue.

A great and easy-to-do activity where students separate the colors in a black marker and develop an understanding that black is a composite of other colors.
