Carolina Investigations For Use With Ap Biology: Transpiration 8-Station Kit

Explore transpiration as a mechanism for plant growth and dynamic homeostasis. Use a simple potometer to study transpiration. Explain water balance as a mechanism of plant homeostasis. Describe the uptake, transport, and loss of water in plants. Observe and analyze how environmental changes affect transpiration rate. Addresses AP Biology Big Idea 2. Students explore transpiration by using a potometer to measure water loss in bush bean seedlings. Then, to extend their new knowledge of transpiration, students design an investigation into the various environmental factors that affect plant transpiration rate. This 8-Station Kit includes enough materials for a class of 32 students working groups of 4.
