These activities let students learn more about the visual system and the
important role of vision in our everyday lives. They are only a starting
point-you'll find many good vision lesson plans and classroom curricula
in print and on the World Wide Web. (See the bibliography.)
- Devise an experiment to test an aspect of vision (such as field of
view, color discrimination, or focusing ability). Test twenty subjects
and graph your results.
- Invent a device that will help you see under specific conditions (for
instance, in the dark, far away, underwater, or behind you).
- Use modeling clay or other materials to create accurate, labeled models
of different eye types. Chose two or three of the following: human, nocturnal
mammal (with tapetum), owl, fly, moth, fish, bird, or reptile.
- Interview someone who has an eye disorder or visual impairment, and
find out how it has affected the person's life.
- Dissect a cow's eye. Supply lists and step-by-step instructions can
be found online at http://www.exploratorium.edu/learning_studio/cow_eye.
- Keep a journal for a week about what conditions affect your vision.
Notice how lighting, distance, and color affect how well you see.
