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.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

This is an activity exploring color and color mixing.
