WebThe daphnia was placed on a slide with cover slip in order to examine its heartbeat by using the microscope. Aim In this Lab we will study the effect of different concentrations of adrenalin on the heart rate daphnia, the water flea. WebMar 16, 2024 · This way one slide would have one Daphnia Magna testing the varying concentrations of alcohol and the other Caffeine. In caffeine we readied concentrations of 0.25%, 0.05%, 0.75% and 1.0% levels of concentration. One member held a bottle of distilled water to be used in between concentrations.

Making the Most of the Daphnia Heart Rate Lab: Optimizing the …
WebWe tested five different daphnia for both ethanol and caffeine trials. Each daphnia was placed in water and their heart rate was recorded to establish a pre-exposure baseline … WebThe chemical substances we used during this experiment were ethanol and caffeine and a control of water. To measure the heart rate of the Daphnia on these substances we counted its heart rate for fifteen seconds and recorded the data. Webexperiment to test the effects of either caffeine, or alcohol on the heart beat rate in Daphnia. Form a hypothesis and design an experiment to test that hypothesis concerning the effect of a substance on heartrate in Daphnia. Week 2: Perform the experiment you designed in Week 1.
