An Experiment to Investigate Factors Affecting the Rate of Photosynthesis In this investigation I will be looking at how the rate of photosynthesis is affected in Canadian pond weed by light intensity. Photosynthesis requires 5 things: Carbon dioxide, water, chlorophyll, light and warmth, these are all called limiting factors. A limiting factor is a factor that determines the rate of a reaction. I will set up the experiment by filling a test tube with water and putting some pond weed in it. I will then turn the test tube upside down and place it in a beaker. I will use a lamp for the light source and to collect the result data I will count the number of bubbles given off by the pond weed per minuet. In this graph the rate of photosynthesis increases proportionally to the light intensity. To make the experiment a fair test I must ensure...
