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.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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

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 activity about light and perception, learners create and observe moire patterns.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

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

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.

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

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners explore how mirrors reflect light and change the way we see things.

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

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

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.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.
