PLANNING Aim: To find out how changing light intensity affects the rate of photosynthesis in pondweed. Prediction: I think that as I change the light intensity the rate of photosynthesis will increase while the temperature will also increase. I will be able to observe this by counting how many bubbles are produced, this happens because during photosynthesis oxygen is a waste product being produced in the air which we can see as bubbles. Preliminary work: I have done some preliminary work in class to predict how I will get my final results. I found out from my preliminary results that as the distance of the lamp is more far away from the pondweed then the average amount of bubbles will decrease and that the temperature will stay constant. I can now see that my prediction for the temperature to increase did not come...
