The effect of altering the light intensity on the rate of photosynthesis of the aquatic plant Elodea

Data Analysis

So that accurate conclusions can be come to we must first put our results into a table of values.

We must now find an average bubble length for each distance, which we can use to draw a graph.  However care must be taken when working out the averages.  We must exclude any readings that are anomalous from the others to ensure the results are as reliable as possible.

Now, so that we are able to make conclusions we must put the results into graphs.



To find any more relationships we must then compare the length of bubble to the light intensity.

Conclusion

After putting the results into graph and table formats we are now able to explain them, coming to sensible conclusions for this experiment.  Firstly we must describe and explain the graphs.

The first graph drawn shows the relationship between the length of bubble produced and the distance the plant was from the light.  From the graph you can see that the further away the light becomes the shorter the bubble becomes (the less the plant photosynthesises).  The graph forms a curve that is very steep from 10-20cm that there but levels off at around ...
