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

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

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

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

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

In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.

Learners use two mirrors to explore how images of images of images can repeat forever.

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 fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

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