In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

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 gelatin as a lens to investigate the properties of laser light.

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

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

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.

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

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

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners explore how nanosized structures can create brilliant color.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

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 explore how polarizing sunglasses can help diminish road glare.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
