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 explore light, color and rainbows by making their own rainbow glasses.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.

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.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

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

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

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, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
