Unformatted text preview: GENERAL BIOLOGY KYLE BI110 – Fall – 2009 8/25/09 I N TRODUCT ION Our general problem was to find out which antibiotic was most effective by measuring the zone of inhibition. The specific hypothesis we came up with was, if the zone of inhibition is largest around the antibiotic then it is the most effective. In the experiment we were measuring the zone of inhibition around each of the antibiotics and the control. The independent variables were the disks with different antibiotics on them with the control being covered without any antibiotic substances. Measuring the effects of each of the different substances is the experimental situation and the blank disc without any antibiotics is the control situation. ME T HODS On the first day we took E. coli bacteria and mixed it with a media (food for bacteria) solution and poured the mixture into a Petri dish. After the mixture solidified we placed four different disks of antibiotics with varying strengths into the dish and added one disk with no antibiotic properties as our control. After waiting a day for the bacteria to develop with no antibiotic properties as our control....
