Things Needed for the Experiment to work:
Michael Kwon, Reona Ido
Biology 11
Mr. Lawrence
Equation for Photosynthesis:
6 CO2 (g) + H2O (l) -> C6H12O6 (aq) + 6O2 (g)

The Scenario: Results were
Temperature
Carbon Dioxide Concentration
Set up the two plants in water solution (each plant has a light source with different voltage: 1Watts per gallon and 3Watts per gallon, make sure you use the variable power supply)
Set the timer to 1 min. Count the bubbles that forms in 1 min
Record results
2 Elodea plants
2 5 gallon water container
2 lamps
2 big beakers
Timer/stopwatch
2 variable power supply
Using bigger gallons so that the temperature wont increase/decrease easily (temperature affects the rate of photosynthesis)
Repeat experiment more than once
Human errors, e.g. recording of the time. increase the values of light intensity tested on the plant
Measurement is not too accurate. How can this be applied in the real world? Eutrophication (a process where water bodies receive excess nutrients that stimulate a bloom of algae)
Plants produce oxygen at a limited pace
Controls phytoplankton and moss.
