Biology Coursework- Photosynthesis Light Intensity Aim: The aim of this investigation is to investigate how light intensity affects the rate of photosynthesis. Plan: I plan to put a pondweed into a beaker filled with 400 ml of water and 100 ml of sodium hydrogen carbonate. Then shine a lamp 15 cm away from the beaker onto it and I will count the number of bubbles for 2 minutes. After recording results will move the lamp away 5 cm further away and start ton record again for 2 minutes. I'm going to do this until the lamp is 35 cm away from the lamp. Variables: Light Intensity - The plant needs light for photosynthesis to occur, so if the light intensity were increased the rate of photosynthesis would increase as well because the chlorophyll would be able to absorb more light. Wavelength (color of light)- The pondweed cannot absorb green light because the chlorophyll itself is green and...
