How the molar concentration of NaHCO3 (Sodium Hydrogen Carbonate) affects the rate of photosynthesis in Elodea. In the experiment I am conducting, I will attempt to discover how the molar concentration of NaHCO3 affects the rate of photosynthesis in Elodea by setting up simple equipment, recording the results as well as attempting to draw some conclusions from my results. I will be looking to find if a relationship/correlation exists between the concentration of NaHCO3 and the amount of bubbles produced during a set duration. Factor chosen: I shall vary the molar concentration of NaHCO3 (Sodium Hydrogen Carbonate) in order to change the concentration of available CO2. My variables: In my experiment, my dependent variable will be the amount of oxygen produced, my independent variable will be the concentration of NaHCO3 and my control variable will be light intensity/distance of lamp from Elodea as well as temperature. Amount of oxygen produced: - the amount...
