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.

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.

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

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

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

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

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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 explore how nanosized structures can create brilliant color.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

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 use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
