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

Sunlight and Photosynthesis in Aquatic Plants

Lab Summary

Use a pH sensor to collect pH data to demonstrate the relationship between photosynthesis and light.


Students investigate the process of photosynthesis in an aquatic ecosystem. They use their pH data to demonstrate the relationship between photosynthesis and light. They also:

  • Understand that for ecosystems, the major source of energy is sunlight and that energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis


Students gain experience conducting the following procedures:

  • Collecting data using the pH sensor
  • Organizing data in simple tables or graphs to identify pH patterns related to light
  • Identifying dependent and independent variables

Sensors / Equipment Used:

PASPORT Chemistry Sensor


Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
