Leaf Stomata as Bioindicators of Environmental Change
Students, in this experiment, collect leaves from two species of trees and the stomatal index on the upper and lower epidermis of each leaf be determined.

Leaf Stomata as Bioindicators of Environmental Change
Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Human Epidermal Cells
Students explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, students label the...
