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.
Before class students are asked to watch two videos, read an assigned handout and complete a quiz. In class the instructor goes over the assignment and addresses any questions. Students will complete an in class quiz individually and their activity in groups. The groups assess their peers work. The instructor reviews the answers and grades the grading. The students then have some multiple choice questions to answer individually (if less than 70% got the answer correct they can re-answer as a group).
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.
