Viewmaster Microscopes: 3-D models photographed in the ViewMaster format illustrate a food chain linking humans to micro organisms.
Delicate Balance: Visitors can place environmental elements onto one side of a scale. When the correct amount of sunlight, oxygen, nutrients, etc are in position, the scale balances and a half-mirrored fish
silhouette is illuminated revealing a happy fish face. If pollution elements are put on the scale, it tips too far and the happy face turns off.
Pollution Panel: Different types and sources of pollution are displayed through openings in the mural. When a lever is pulled, new images slide into place illustrating things that can be done to correct or reduce the
problems.
