In this lesson, students will explore the effects of various environmental conditions on the rate of transpiration from the leaves of a plant.

• Students will enhance their understanding of the process of transpiration.
• Students will manipulate the environmental factors of temperature, relative humidity, and wind and observe the effects on transpiration rates. They will then observe and analyze a graphical representation showing these factors.
• Students will extend the concept of transpiration rates to a similar process in humans.

• gradient
• photosynthesis
• relative humidity
• stomata
• transpiration
• turgor pressure

This lesson involves students using TI-Nspire™ technology to model the effects of various environmental conditions on the rate of transpiration from the leaves of a plant.
As a result, students will:

• Better understand the process of transpiration.
• Predict the effect of these environmental conditions on the plant.
