In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

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 use an old CD to construct a spectroscope, a device that separates light into its component colors.

This is an online activity about what would happen if we could travel at or near the speed of light.

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.

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 set up a night time insect observation station with a light and sheet.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

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

A magic lantern is a light that projects an image onto a screen.

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.

This activity guide includes instructions for building a spectroscope using a standard classroom overhead projector.

In this activity, learners make a photographic image—without a camera!

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 activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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 will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?
