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.
