In order to collect accurate data from an experiment, it is important to evaluate the environment that the lab will be taking pace. While my lab partners and I were doing this, we checked to see if the workspace is clean and clear of an unnecessary or harmful objects, especially food. Then our second step was to gather all the necessary supplies for the experiment. This included, a microscope, three glass microslides, alcohol, caffeine, and water, four pippets, then finally three water fleas. After our workspace was ready we took the first flea and placed the flea on a glass plate then carefully latched the plate onto the microscope. Once the third team mate located the water flea on the microscope, I placed one single drop of water from

Flea number two was placed on a glass microscope and latched onto the microscope the same process as flea number one. Once 30 seconds was up she reported flea number two also had a heart rate of 60 beast in 30 seconds. My group and I wasted no time we then filled the pipet with caffeine and I placed one drop on top of flea number two, after administering caffeine to the water flea it immediately begun to rapidly jump around. This cause and issue because my partner was unable to find the flea on the microscope or count the heartbeats. We waited til the flea stopped moving then we were able to count the heartbeats, the caffeine ended up speeding the water fleas heart rate to 67 beats per 30 seconds, which might explain the rapid movements. We then prepared our last flea, flea number one onto the microscope. We added a single drop of water and calculated 56 beats per 30 seconds, I then added one single drop of alcohol to the flea. To our surprise the flea only jumped once which allowed us to quickly be able to find the flea again on the microscope and count the heart rate. Alcohol slows the heart rate of flea number one to45 beats per 30 seconds, the reaction of the flea was most likely shock. The graph below further shows the fluctuation of the water fleas heart rate and
