The Effect of Caffeine on the Heart Rate of Daphnia

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 they are exposed to light, they are also exposed to heat in which they aren’t used to. ↠ Moreover, when they are given caffeine of a high concentration their heart may beat so fast that will cause their death. ↠ Furthermore, there is the†¦show more content†¦|Treatment |Heart Rate per 30 seconds |Mean from each experiment in heart | | | |beats min-1 | |1st Trial |2nd Trial |3rd Trial |4th Trial | | |Pond Water |122 |164 |188 |185 |341 | |Caffeine (0.125%) |410 |440 |/ |/ |425 | |Caffeine (0.25%) |200 |204 |/ |/ |404 | |Caffeine (0.5%) |162 |/ |/ |/ |324 | | These results are better depicted by the following chart. Conclusions: The chart does not confirm what our hypothesis was: that the higher the concentration of the caffeine solution the more the beats per minute of the daphnia. This, though, might be a mistake since the caffeine solution may not have been exactly as we wanted it in each occasion, hence making the results inaccurate. Also, when trying to press the â€Å"=† button of the calculator faster, many of those additions were not calculated since the calculator can’t add as fast as we press the button. Evaluation: If I were given the opportunity to repeat the experiment these are the parts of it that I would change: ↠ I would repeat the experiment with the caffeine solution more times, so that the results I would get will be moreShow MoreRelatedThe Effect Of Caffeine On The Heart Rate Of Daphnia1114 Words   |  5 Pagesexperiment was to see if caffeine had an effect on the heart rate of Daphnia (water fleas) by observing them under the microscope and recording their heart rate over a period of time in concentrations of caffeine.

In order to measure the basal heart rate, various Daphnia were obtained and observed The Effect Of Caffeine On The Heart Rate Of Daphnia Effect of Caffeine on the heart rate of Daphnia Abstract In this experiment we find how caffeine can affect the heart rate of a culture Daphnia. Heart rate of a living organism’s can vary depending on the individual, age, body size, heart conditions, medication use and even temperature. This report will examine if the caffeine is good or bad for the living organism’s health and body. And discuss about where the caffeine is produced and used in daily life of human beings and on the environment. Daphnia is a water flea used in this experiment because of its genomic infrastructure with wide range of phenotypic diversity. This quality of Daphnia makes them a versatile model for the experiment. Also their transparent body allows the experimenter to visually see how the heart beats and count them under the light microscope during the experiment as required. The heart rate of Daphnia is monitored under different concentration of caffeine solution and the results are shown in a table and a graph. Experiment carried out to locate the effects of caffeine on a heart rate of Daphnia may or may not be a predictor of change in human heart rate under caffeine. The effects of caffeine can also be tested on humans but those experiment involving humans contains high risk, as Daphnia can only live for a short period of time and in nature most of them get eaten within their first few days or weeks of life.

As caffeine is a stimulant, a prediction was made that caffeine would increase the heart rate of the Daphnia. Method To conduct this study a culture of living Daphnia were collected from a nearby natural water source area. A light microscope was set up with the light on a low setting; one large Daphnia was selected and placed in the centre of a cavity slide by using a pipette. The Daphnia and the cavity in the slide was surrounded by a ring of cotton wool, this restricted the movement of the Daphnia making it easier to count its heart rate under the microscope. No cover slip was used as it would have damaged the water flea and stopped its oxygen supply. Before placing the slide under the microscope, a tissue was used to remove the pond water around the Daphnia and with a pipette plain water was added to the cavity slide. As soon as the water was added a timer was set for two minutes and the slide was placed under the microscope. Steadily adjusting the controls on the microscope the Daphnia was made visible and the heart was located through its translucent body.
