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

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

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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 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.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

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 use a compact disc to make a spectrometer, an instrument used to measure properties of light.

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 why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

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

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

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