1) Construct a graph of your data2) Using the graph, estimate http://research-paper-for-sale74.mystrikingly.com/ the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to 26/50 leaf disks. 3. What variable were you testing in this investigation?We were testing the leaf disks as the control. The white light, and the water were the controlled variables. 4. Explain why the leaf disks started to float after being exposed to white light. The leaf disks started floating after being exposed to white light because the process of photosynthesis is light- dependent. Light is required for the process of photosynthesis to begin and so the disks would not start floating unless they were placed under the sun, or in this instance the white light.In this investigation, you measured the rate of oxygen production.
