This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

In this activity about light, learners explore how water can refract light and change the way they see things.

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 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 color by examining color dots through colored water and the light of a flashlight.

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

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

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

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.
