In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

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 activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this activity, learners explore how mirrors reflect light and change the way we see things.

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 how polarizing sunglasses can help diminish road glare.

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

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

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

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

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 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 investigate how bats use echolocation to navigate. One learner is assigned to be a bat, while the other learners are selected to be either moths or trees.

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

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

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

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.
