Introduction Photosynthesis is a process where plants make glucose food using sunlight as an energy source. The word equation for photosynthesis is Carbon dioxide + water      glucose + oxygen Chemical is 6co g + 6h 0L      c6h o L The factors that affect the rate of photosynthesis are the intensity of light, the temperature, concentration of water and the concentration of carbon dioxide. Chlorophyll absorbs sunlight and makes the energy from sunlight for other chemical reactions in the plant. It converts light energy to chemical energy. Any surplus glucose is turned into starch...
I would collect the oxygen under water or in a syringe so I could measure exactly how much oxygen was being produced. I would control the environment. I would also try to measure the amount of oxygen that is dissolved in the water as it will diffuse out of the water and will collect with that oxygen that is coming from the plant.

I would also change the direction of light and have a more focused light source. I would vary the power of the bulb for intensity, and I would try this with different species of plant.
