Vernier - Transpiration

Activity Overview

In this lesson, students will use the gas pressure sensor to observe the overall transpiration process in plants.


  • Observe how transpiration relates to the overall process of water transport in plants.
  • Use a handheld interface and a Gas Pressure Sensor to measure the rate of transpiration.
  • Determine the effect of light intensity, humidity, wind, and temperature on the rate of transpiration of a plant cutting.
