Water fleas are said to be good bioindicators, so our main goal was to prove this by doing different tests to see if they are reacting as expected, and if they really are a good bioindicator or not.
The main goal was to see how the heartbeat of the water flea changes when it’s in contact with different substances, some that are tranquilizers and others that alter them, and see if these substances produce the same effect as in humans. In order to test this theory, we collected water fleas, and after having enough, we started producing the necessary substances and preparing them in the right way. Finally, the fleas were put in each of these substances; they were left in them for different periods of time, and then we counted the heartbeats per minute, and with those results, we were able to test our theory and produce the conclusions.
The conclusions tested our hypothesis and proved our theory right. During this project, we did not only see how the fleas' hearts react; we also learned more specific facts about the water flea and their life cycle, and the result of our work is developed on the following website.
