Carolina Investigations® for Use with AP® Biology: Transpiration 8-Station Kit
Students investigate water loss in plants as they build toward an understanding of osmoregulation and plant responses to the environment. In the Guided Investigation, students construct and use a simple potometer to measure water loss from transpiration of bush bean seedlings. In the Inquiry Activity, students explore a question about one of the various factors that affect the rate of transpiration. Kit includes enough materials for 8 groups.
