An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on Canadian Pondweed Background Information: Photosynthesis is an organic chemical reaction which green plants use to produce glucose from carbon dioxide and water. Its equation is 6CO[2] + 6H[2]0 C[6]H[12]O[6] + 6O[2] However, carbon dioxide and water cannot react on their own "They have to be given energy to make them combine. The energy which green plants use for this is sunlight energy". We can determine that if sunlight gives the reaction energy, and increase in the intensity of the sunlight will give the reaction more energy, which will speed the reaction up. We can therefore safely predict that as the intensity of the light increases, so too will the speed of the reaction. List of Key Variables: The key variables that could affect my experiment are the temperature at which the water is, a thermometer...
