Planning an experiment to find out if light intensity alters the rate of photosynthesis of a plant Introduction In this experiment I am trying to find out if light intensity alters the rate of photosynthesis of a plant by using waterweed in different light intensities. I would have to consider rate-limiting factors such as the amount of carbon dioxide in the water. To make sure the carbon dioxide supply does not run out, sodium hydrogen carbonate could be added in the water. A temperature rise may cause photosynthesis to speed up, so in order for this experiment to be a fair test I would need to keep the water at a constant temperature from the beginning of the experiment. I would also need to know if the bubbles of gas produced by the plant is oxygen. To do this, I would check to see if a glowing splint re-lights in the gas...
