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.

  • The use of conceptual questions encourages student engagement;
  • Peer instruction and grading encourages engagement and reduces instructor workload.


  • Given the nature of the activity, keeping students on task and answering questions can be challenging.


  • 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.
