Indented Daphnia Experiment

We took an indented microscope slide and out the daphnia on it with water and put another intended slide over it. After that, we put the slide into room temperature water (18 degrees Celsius) to measure the daphnia’s normal heartbeat per minute. After that, we put the slide under the microscope and counted the number of beats per 15 seconds. We then repeated the procedure with water that was 4 degrees, 8 degrees, 26 degrees and 33 degrees Celsius.
