Abstract

The purpose of this project was to find the relationship between school divisions and the amount of bacteria in everyday places. The tested locations were 1) water fountain buttons, 2) doorknobs, 3) computer keyboards,4) desks, and 5) bathroom sink faucets. In order to find the amount of bacteria in each place, a cotton swab was swabbed on each location. The contaminated cotton swab was then placed on the petri dish using aseptic technique. Each petri dish already contained agar, that had been made and poured twenty-four hours beforehand. The hypothesis for this study states that if the amount of bacteria is compared between school divisions, then there will be a relationship between the amount of bacteria and school divisions. If there is a relation between school divisions and the amount of bacteria, then the lower school division will contain the most bacteria. The null hypothesis states that there will be no relationship between school divisions and the amount of bacteria. This experiment will benefit other schools because they will learn which division needs to be cleaned with more attention. Surprisingly, our results did not support our hypothesis, because the middle school showed the greatest amount of bacteria, when it was hypothesized the lower school would.
