Biology Lab Materials and Methods A single Daphnia is placed on a microscope slide with a depression well and covered with one or two drops of water. The Daphnia is then covered with a cover slip and placed under the microscope. Look through the microscope and count the number of heartbeats in one minute using a stopwatch. Record this data on a chart. Then, using the same daphnia, extract the water from the well where the Daphnia is and replace it with one to two drops of 5 % alcohol. Place the daphnia under the microscope and count the number of heartbeats in one minute using the same procedure.
