I chose to investigate the different concentrations of caffeine on the heart rate because I wanted to see how it impacts the human heart when the concentration of caffeine is increased. Does the heartbeat stay consist, drop, or increase?  I hope to find out that with an increase of concentration given to the daphnia the rate of the heartbeat should also increase.
