In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

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 activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

This is an activity exploring color and color mixing.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
