How does Carbon dioxide affect the photosynthesis rate of waterweed?

lab report for my IB assesment.  experiments on the photosynthesis rate of water weed, by adding carbon dioxide into a beeker with water where the a branch of water weed is placed. A branch of the water weed is placed in a cylinder and a test tube inside of the water. It is held by a stand. used different rates of carbon dioxide going from 6ml to 10ml in the amount of 600ml of water.  used a stopwatch to measure the time of 5 minutes each time and counted the amount of bubbles appearing in order to investigate on the photosynthesis of the waterweed. Included in the Essay: Hypothesis,Background information,Process Data,Processed Data,Sample calculations,Evaluation,Conclusion.
