and caffeine has an effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart to beat irregularly. Studies show that caffeine consumption

Hypothesis: As the caffeine concentration rises‚ so does the mean heart rate of daphnia. Risk Assessment: In this experiment there are the following risks both for the human that carries out the experiment and the daphnia: ← The human that carries out the experiment should be cautious not to touch the lamp with wet hands since it uses electricity. ← Also‚ be careful not to spill any of the pond water on the floor. ← As for the daphnia‚ there is a chance for them to die as when

03 - 31 - 2006 RESULTS: In this experiment the effect of different hormones on heart rate of _Daphnia_ was examined. It was investigated which substances act as stimulants and which substances act as depressant. Initially‚ _Daphnia_ was placed on depression slide under the microscope and the average heart rate was determined. Subsequently‚ _Daphnia_ was treated with different type of hormone and the effect on Daphnia heart rate was observed. It was investigated which substances act as stimulants
