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 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.

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

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

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, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
