Daphnia Experiment Results

: If daphnia are exposed to poor water quality from manmade factors such as car antifreeze, plant pesticide and cigarette ash then their quality of life decreases and changes their behaviors and potentially kills them because the harsh chemicals cause their natural functions to shut down and cause death. Although my hypothesis was partially correct I believe there are more factors than just the introduction of chemicals that would weaken the daphnia. Before my experiment I had designed my plan to observe the daphnia for an hour but I had to change my time to a half an hour due to lack of time I had left after setting up my experiment. I would observe two petri dishes at a time rather than all 4 at the same time. If I could redo my research
