In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

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

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

In this activity, learners use their imaginations and picture a scene in their heads.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.
