In order to better understand how everyday items can harbor potentially dangerous germs, Mrs. Hill’s food sciences class performed a bacteria lab after returning to school from Christmas break. We followed them throughout the process, and these are the results.

  • Hill sent students out with q-tip and gave them certain objects or places to swab, some of which included door handles, basketballs in the gym, the toilet handle in the boys’ bathroom, cell phones, and kitchen counter tops.

  • After the students completed swabbing each object, Hill rubbed the swab on a gelatin mixture. Over time, bacteria started to grow on this mixture.

  • We went back every couple days to check in and see the progress and bacteria growth. At first, there was no growth.

  • "Some of the door handles and counter tops haven't been cleaned in around three weeks, it will be interesting to see how this lab turns out," Hill said. She has done this lab in the past, but this is her first year preforming it at the high school.

  • Although the first few days yielded no results, after the gelatin sat over a long weekend, changes began to show.

  • The kitchen counter tops grew the most bacteria by far. The results of the lab were surprising, as many students don't take the time to think about how dirty certain surfaces can be.
