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

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

This activity (aka "snack") provides instructions for discovering your blind spot. It is an exploration of light and visual perception using simple materials you may have around the house.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

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

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 activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

In this activity, learners determine the necessary conditions for pea seed germination.

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 make optical fibers out of strips of gelatin.

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

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

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 optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.

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

In this activity, learners create a water prism to break light into the seven colors of the rainbow.
