Photosynthesis-Cellular Respiration Cycle

New Review

The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes with carbon dioxide and oxygen indicator and snails. Their observations lead to an understanding of the reverse processes.

Instructional Ideas

  • Use a Venn diagram to compare and contrast photosynthesis and cellular respiration
  • Add a test tube with water plants to the experiment for additional observational data
Classroom Considerations

  • Allow at least an hour between the two parts of the activity for reactions to occur
Pros

  • Includes an answer key of expected responses
  • Gives individuals a concrete reference for a complex concept
Cons

  • None
