Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
