HOW DOES LIGHT INTENSITY AFFECT THE RATE OF PHOTOSYNTHESIS? Aim The aim of my experiment is to find out if the intensity of light affects the rate if photosynthesis in Canadian Pondweed (Elodea). I will measure the number of bubbles produced in two minutes. I will change the light intensity on the Elodea to be the input variable. I will do this by moving a bench lamp closer or further away from the plant. I will add sodium hydro carbonate to the water to aid the photosynthesis. Sodium hydro carbonate produces Carbon Dioxide. Background Knowledge Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production of simple sugars from carbon dioxide and water causing the release of sugar and oxygen. The chemical equation for photosynthesis can be expressed as: Carbon Dioxide + Water Glucose + Oxygen 6CO2 + 6H2O ...
