29 MARCH 2003 SCIENCE INVESTIGATION RACHEL BEESLEY INVESTIGATING THE LINK BETWEEN THE RATE OF PHOTOSYNTHESIS AND LIGHT INTENSITY INTRODUCTION The aim of my investigation is to see if different distances of light affect the rate at which a plant photosynthesises. To do this, I am going to conduct an experiment which will involve putting some pondweed into a test-tube of water and using a lamp to alter the light intensity. I will be able to measure how fast photosynthesis is taking place (the reaction rate) by counting the oxygen gas bubbles given off. I predict that if the lamp is closer to the pond-weed, the reaction rate will be quicker and more oxygen gas bubbles will be produced. This is because sunlight is needed for photosynthesis to take place, so if more sunlight (or in the case of this investigation, light from a bulb) falls...
