Overview
This activity examines the light dependent reactions of photosynthesis.
In groups students answer questions relating to the electron transport chain, photosystems I & II, and photosynthetic pigments. The students are invited to consider various hypothetical scenarios and are provided ample structured time to consider and explain their implications. Finally, a table comparing non-cyclic and cyclic photophosphorylation is completed.
Instructional Objectives
- To develop a better understanding of the light dependent reactions of photosynthesis;
- To appreciate the role of photosynthetic pigments and the electron transport chain.

Tips
Benefits
- The use of conceptual questions encourages student engagement;
- Peer instruction and grading encourages engagement and reduces instructor workload.
Challenges
- Given the nature of the activity, keeping students on task and answering questions can be challenging.
Tips
- Instructors can make the students check each other’s work throughout the activity;
- Keep students on task by using a visual timer (e.g., a computer clock on smart board), and by reminding them how much time they have left to complete the activity.
