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 optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Learners use two mirrors to explore how images of images of images can repeat forever.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.
