Sophie Louise Beard The Effect of Carbon Dioxide Concentration On The Rate of Photosynthesis Aim To investigate the effect of carbon dioxide concentration on the rate of photosynthesis. Prediction I predict the higher the carbon dioxide concentration (sodium hydrogen carbonate solution concentration) the faster and higher the rate of photosynthesis will increase meaning more oxygen produced (more O bubbles given off) over a period of time [2 minutes]. The amount of carbon dioxide taken in I predict will be proportional to the amount of oxygen given out. E.g. 6CO +6H O --> C H O +6O As the amount of CO O I predict the graph will look something like this At the end of the graph, it will eventually level off and stop producing oxygen due to the limiting factors. Diagram Variables Things we could change which would effect our results are -: * Amount of light intensity * Amount of carbon dioxide(sodium hydrogen carbonate solution molar) * Different conditions (temperature) * Amount of pond weed ...
