Our research can help the world by demonstrating the relationship between blood pressure and heart rate. It is already known that heart rate has a large effect on blood pressure, however, we hope to determine if the opposite is also true. This research can contribute to helping people live longer by reducing the amount of heart attacks and strokes caused by high blood pressure.
Recap
In our experiment, we wanted to determine the effect of green tea powder on the heart rate of Daphnia Magna in order to determine whether or not it would be comparable to the blood pressure medications ramipril and digoxin. Our hypothesis was that green tea powder would lower the heart rate, but not as significantly as the actual medicine. In order to test this, we made solutions of each of the three treatments and applied one drop to each daphnia sample. They were then observed underneath a microscope and the heartbeats was counted visually in beats per minute. The reason we were testing this hypothesis was to determine if green tea has a comparable effect on heart rate to actual blood pressure medication, as blood pressure and heart rate have a close, direct relationship.
The result of our research was that there was no significant difference between the averages of the treatments. This led us to reject our original hypothesis that all three treatments would lower heart rate, with digoxin and ramipril being the most effective. In actuality, the two medications had little effect on heart rate, and the green tea powder even raised it. This is thought to be a side effect of the caffeine present in the tea, which we did not expect to have an effect as significant as it actually was.
