The Exploratorium is more than a museum. Explore our online resources for learning at home.


At the Exploratorium, we dissect cows’ eyes to show people how an eye works. This Web site shows photos and videos of a dissection. If you try this at home, wash your hands after the dissection. Wear latex gloves if you have cuts in your hands.

Here’s a cow’s eye from the meat company. The white part is the sclera, the outer covering of the eyeball. The blue is the cornea, which starts out clear but becomes cloudy after death.
