Rate of Photosynthesis In this experiment I will be investigating the effect of light intensity on the rate of photosynthesis. The variables available to me are: * Distance of light source from plant * The wattage of the lamp * The amount of leaves * Size of Elodea plant The variable I am going to investigate is the distance of the light source from the plant as it is the easiest variable to measure. Diagram Method We placed upside down Elodea plants in water filled gas jars and counted the bubbles coming from upturned bottom of the stem. The amount of bubbles that came from the plant was noted. Prediction I predict that when we decrease the distance from the lamp to the plant (increase the light intensity). The rate of bubbles that will be produced will increase until it reaches a certain rate where increasing the light intensity will not effect the rate of bubbles produced, I think this because at...
