    The results from the experiment generally show the trials with full light intensity to have produced more oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the…

When I think of decisions I have made that were flawed, I immediately think of a chat session I had last week…
