In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

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

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

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

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.

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

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

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

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
