In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

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

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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 will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

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 optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners make their own heat waves in an aquarium.

This is an activity exploring color and color mixing.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

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.

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.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
