This animation demonstrates how we took water from the different beakers with the dropper and dropped about 3-4 drops of water onto the daphnia. We wound up not using the VERY cold water because it was too cold for the fish to survive in, and by the time we got around to testing the daphnia's heart rate in the VERY cold water, most of the daphnia had died in their container (see error in Analytic Essay for more detail on why we could not test using the VERY cold water)!
