Students learn some ways to investigate the sense of sight, and find out how to plan and conduct their own experiments.
In the "CLASS EXPERIMENT," students measure their central and peripheral visual fields under different circumstances, and learn which areas of the retina carry these types of information to the brain.
In "TRY YOUR OWN EXPERIMENT," students design experiments, investigating, for example, what happens when the visual field is restricted, or what other animals see in their visual fields.
