Features 13 core lab activities covering the fundamental concepts of physiology, ecology, plant systems and more
Use a weather sensor to measure the change in humidity and temperature of a small potted plant over a 24-hour period.
In this activity, students investigate transpiration in a land plant. Students use a weather sensor to record data on a plant's environmental conditions inside a closed system while they:
- Define transpiration and explain where it occurs
- Describe how a plant can control the rate of transpiration
- Explain how different environmental conditions affects the rate of transpiration
- Describe the movement of water through a plant
Students gain experience conducting the following procedures:
- Setting up the equipment and work area to measure the change in humidity and temperature Watering a small potted plant and then wrapping the pot and soil surface in aluminum foil to prevent moisture loss
- Enclosing the potted plant and weather sensor in a sealed plastic bag
- Measuring humidity and temperature over a 24-hour period
- Using math skills to interpret and analyze data
Sensors / Equipment Used:
Measures barometric pressure, relative altitude, absolute and relative humidity, dew point, and temperature. For use with PASPORT Interfaces.
