Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.
6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....
Factors Affecting Rate of Photosynthesis.
Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.

Therefore in graph (c) the horizontal axis could be also labelled relative light intensity, a proportional linear relationship with the rate of photosynthesis.

Prediction : I predict that as I increase the distance between the light source and the Canadian Pondweed (reducing the light intensity), the volume of oxygen produced within the time limit (the measure of the rate of photosynthesis) will decrease.
Temperature affect the rate of photosynthesis experiment
I think this
because I already know that a plant needs sunlight to be able to
perform photosynthesis as shown in the formula below:
Water + Carbon dioxide>> Sunlight>> chlorophyll>> Glucose + oxygen
Also I know that if you increase anything on the left-hand side of
this formula (the part I have boxed on the diagram above), everything
on the right hand side will increase (Increase of input = increase of
output.)This means that if the concentration of light were to be
increased, the levels of glucose and oxygen (The rate of
photosynthesis) will increase.
Effect of Temperature on the Rate of Photosynthesis.
It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
The Effect of Extreme Temperatures on the Rate of Photosynthesis 2
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.
and carbon dioxide affect the rate of photosynthesis
more accurate results I will repeat the experiment 3 times if possible
Using my scientific knowledge and the research that I have been doing
I would predict that light intensity will affect the rate of
photosynthesis in this way: The closer the lamp is to the elodea the
stronger the light intensity will be, I know this because we have
being doing tests to measure the light intensity using specialist
