Features 13 core lab activities coverign the fundamental concepts of physiology, ecology, plant systems and more

Photosynthesis

Lab Summary

Use a light sensor and absolute pressure sensor to measure the change in light and pressure in an aquatic ecosystem as an Elodea or other aquatic plant undergoes photosynthesis.

Theory

In this activity, students investigate the rate of photosynthesis in an aquatic plant using an absolute pressure sensor and a light sensor while they:

  • Explain the process of photosynthesis
  • Describe the factors that affect the rate of photosynthesis

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the change in light and pressure in an
    aquatic ecosystem as an Elodea or other aquatic plant undergoes photosynthesis.
  • Measuring the changes in pressure, temperature, and light in the Elodea's environment
    throughout a cycle of light and dark.

Sensors / Equipment Used:

PASPORT Light Level Sensor

(PS-2177)

Can be used as an absolute reference by detecting and measuring light in LUX.
