Daphnia heartbeat experiment book
http://ei.cornell.edu/toxicology/bioassays/daphnia/ WebThe aim of the experiment is to observe the changes and determine the effect of alcohol (ethanol) on the heart rate of Daphnia. If ethanol is added to the environment of Daphnia, then the number of heartbeats per minute of daphnia will decrease, when compared with control solution of distilled water.

WebSep 4, 2016 · The concentration of the caffeine in the blood of Daphnia will determine the heart rate of the Daphnia. It will be directly proportional to each other, meaning that the increase of the concentration of the caffeine will give an increase of the heartbeat.

WebDependent variable The dependant variable in this experiment is the heart rate of daphnia that was measured in beats per minute, also a continuous variable. We measured this by counting how many times the daphnias heart beat within the space of a minute by looking through a microscope at the daphnia. WebYou will need a microscope for observing Daphnia closely enough to monitor heart rate. Either a dissecting microscope or a compound microscope with low-power objective and a depression slide could be used.
