Gabriella Armstrong An Experiment Investigating the Rate of Photosynthesis in a Water Plant Introduction Photosynthesis is the process in which carbon dioxide and water are converted into glucose and oxygen. The reaction requires light energy, which is absorbed by chlorophyll. This process can be represented using an equation: Carbon dioxide + Water (+ light energy) → Glucose + Oxygen Research Question The objective of the experiment was to find out if light intensity affects the rate of photosynthesis in aquatic plants that are naturally found in water. This would be observed by the amount of oxygen bubbles released in water during photosynthesis. By shining a light at different distances to the Elodea plant a trend may be observed between light and the rate of photosynthesis. Elodea Canadensis will be used as the aquatic plant in the experiment since it has been proven in similar experiments that they release oxygen bubbles during photosynthesis. If similar results are obtained, then they results will increase the validity of experiments with comparable findings. Baking Powder will be added to the water that the Elodea will be placed in since it will increase the amount of carbon dioxide due to the fact it will enhance oxygen production in the Elodea during photosynthesis. Hypothesis When the light is at a closer distance to the Elodea plant, the amount of oxygen bubbles produced in 2 minutes will increase displaying the high rate of photosynthesis. Light is required in order for the process of photosynthesis to function correctly, therefore the higher the light intensity then the rate of photosynthesis will increase too. Variables Independent Variables | The independent variable will be the distance that the light is away from the Elodea plant since this needs to be changed to impact the dependant variable. | Dependant Variables | The
