In this study I am going to investigate the effect of caffeine on Daphnia (water fleas) heart rate. I shall use daphnia as they would never have been exposed to caffeine before‚ unlike a human‚ who may have already developed a high tolerance to it. Another reason is that Daphnia have a very translucent body; therefore‚ it is relatively easy to see their heart under a microscope‚ which makes it easier to count the number of heartbeats‚ thus‚ making my results more accurate.

The results of the statistical test did not support the hypothesis. The statistical test proves that the null hypothesis can be accepted regarding temperature impacting weight. However‚ we accept the hypothesis regarding conductivity. The test shows that the conductivity of a cell submerged in a solution can be altered with changes in temperature as the independent variable. However‚ the test shows that we accept the null hypothesis for weight change because weight is not impacted by temperature
