Sampling Carbon Dioxide
Students perform an experiment to determine which source of gas (their breath, exhaust from a car, or the air in the classroom) has a greater concentration of carbon dioxide. Students compare the colors of BTB solutions after...
Curated OER
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.
