Biology Coursework Light Intensity and The Rate Of Oxygen Output Aim The aim of my experiment, which is investigating Light Intensity on a piece of Canadian pond weed, is to find out and investigate whether or not changing a variable of the pond weed will affect other variables such as ; The plants rate of oxygen output ; The effect on the plants photosynthesis In my experiment I am going to change one variable which will be light intensity. Prediction and Background Knowledge I predict that as the light Intensity increases so will the rate of oxygen output. I know this will happen because plants need light for photosynthesis. The following formula represents photosynthesis: Carbon Dioxide + Water Sunlight Glucose + Oxygen Chlorophyll I know by this formula that as one of these variable changes and it gets bigger, so to will the end result, which in my case will be oxygen, bubbles. We know that the four things that are needed...
