In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

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

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

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 about light and reflection, learners discover that what you see is often affected by what you expect to see.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, learners investigate procedural memory.
