Photosynthesis Coursework Thomas Hansen I have been given the task of analysing and evaluating an experiment carried out by year 10 students to find the optimum distance for a lamp to be placed to enable aquatic plants to photosynthesise. Here is a table of results showing what five different groups recorded. Number of Bubbles Recorded in Five minutes Distance Group 1 Group 2 Group 3 Group 4 Group 5 Average (1.d.p) 0cm 32 48 36 96 21 46.6 10cm 39 45 36 110 27 51.4 20cm 26 52 29 58 32 39.4 30cm 10 27 11 38 45 26.2 40cm 3 7 1 15 7 6.6 50cm 2 2 1 5 0 2 60cm 1 2 1 4 1 1.8 I have drawn a graph to illustrate the average values of these groups. As you can see, there are three clear sections to the graph, labelled A, B, and C. The shape of the graph shows a steady increase in the amount of bubbles given off through the experiment, showing a clear optimum distance for the light, and levelling out where the lamp is so far away it adds an almost negligible amount to the background light. The optimum distance according to these results is 10cm, where the average amount...
