Aim
To work out how light intensity can affect the rate of photosynthesis.

Hypothesis
I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is, the more photosynthesis, the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because light intensity is also a limiting factor of photosynthesis, the rate of photosynthesis could go up and up and reach its maximum level. So, if it would be shown in a graph, the graph would show a line going up and up and eventually continuing as a straight line. The straight line is due to the limiting factors of light intensity (Carbon dioxide and concentration of Chlorophyll).
Glucose + Oxygen (+ light) Carbon dioxide + Water
