Transpiration
Make the transpiration process clearly visible to students - avoid the difficulty of traditional potometer setups. With this Barometer/Low Pressure Sensor your students will see meaningful graphs of the transpiration effect as it happens. Explore the process by using just a plant sample and the sensor (which includes tubing). Students will further experiment by using a fan to increase the evaporation and a plastic bag to increase humidity effect.
