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 estimate risks associated with different events and compare their estimates to the real possibilities.

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 (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.
