Investigating Transpiration Lab Activity
Students use several techniques to investigate the location, methods, and mechanisms of transpiration in plants. Students first determine the source of water loss and confirm their findings with a qualitative chemical test. Then they prepare microscope slides of xylem in stem tissue, and prepare a leaf imprint using an innovative method that vividly highlights stomate structures. Finally, using WARD’S specially-designed potometer and supplied materials, students subject bean seedlings to varying environmental conditions to determine how transpiration is affected. You’ll get enough materials for eight setups, a teacher’s guide, and student copymaster.
