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 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

In this activity, learners overlap the three primary colors to see how all other colors are made.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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).

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, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity about light, learners explore how water can refract light and change the way they see things.

This is an online activity about what would happen if we could travel at or near the speed of light.

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

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.
