Plants in a Bottle: Photosynthesis and Respiration
Catalog #STO-144
How do environmental conditions affect oxygen production and use?
Time to complete: 1-2 forty-minute class period(s)
Conduct simulated oxygen and carbon dioxide tests to investigate the amounts of oxygen produced and used by aquatic plants under various environmental conditions.
Test simulated water samples from bottles containing plants exposed to different light levels.
Collect and analyze data from a controlled experiment to determine how photosynthesis and cellular respiration affect the oxygen concentration.
