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

In this activity, learners control the (apparent) size of a hole with their brain.

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.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.

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 (17th on the page), learners investigate why you cannot see colors in dim light.

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

In this activity, learners make a Benham Top to explore visual illusions and optics.
