Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

In this story time program, young learners listen to the Dr.

In this artistic activity, learners blow up a smaller picture into a larger one, by using a grid.
