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.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

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

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

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

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

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?

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

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

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

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

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

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

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
