In this practical, students will investigate the effect of light intensity on the rate of photosynthesis in pondweed or another suitable aquatic plant. The oxygen is collected and measured to allow a calculation of the rate of photosynthesis. Light intensity is varied by moving a lamp closer to the plant.
The worksheet contains equipment, method, table of results, graph and focused questions.
This activity is designed to promote independent learning, allowing teacher to circulate room and support students who need guidance.
