Photosynthesis and Respiration in Seagrass - COSEE Coastal Trends

Lesson Plan 

Students conduct a hands-on experiment that illustrates how different levels of light affect photosynthesis and respiration in seagrass. Note: instructor may need to be creative with timing of the experiment to allow for an adequate incubation period.

Concept: Photosynthesis
Photosynthesis by marine plants produces much of the oxygen in the atmosphere and uses much of the carbon dioxide.
