Biology Lab Report Outline I. Introduction a. Anti-bacteria soap verses no anti-bacteria soap b. Effectiveness of the soap killing germs when hand washed c. Hypothesis: The anti-bacteria soap will eliminate more bacteria than the soap with no anti-bacteria. d. Brands tested: Lysol and SoftSoap II. Materials a. Two Petri dish b. Lysol anti-bacterial soap (active ingredient: Benzalkorium Choloride) c. SoftSoap band soap without anti-bacteria d. Parafilm e. Marker III. Methods a. Gather as many bacteria as possible in your hands. b. Obtain 2 soap to test in the experiment c. Obtain 2 petri dishes. d. My lab partner and I drew a line in the center of the petri dish, labeled one side dirty, and the soap. e. I finger printed on the dirty side on one of the petri dish, while my lab partner did the same for the other petri dish. f. I washed my hands with the anti-bacterial soap and fingerprinted my finger on the side labeled soap. g. My lab partner did the same for her petri dish. h. We then closed the lid, sealed it with Parafirm, and placed it in an area with moderate sunlight for one week. IV. Results a. The Lysol soap appears to be lighter than the SoftSoap soap. b. The Lysol soap has similar amounts of bacteria on both sides, slightly favoring the clean side of having less. c. The SoftSoap appears to have fewer bacteria on the clean side, than on the dirty side. V. Discussion a. The experiment did not support the hypothesis. In fact, the non antibacterial soap (SoftSoap) appears to be more effective than the antibacterial soap (Lysol).
