The data was then recorded in a data table and the average amount of bacteria for bananas and bread was calculated by averaging the three trials. This completed our experiment. Results Before dropping the banana and bread on the floor we recorded the amount of bacteria on the fresh banana and bread, the results are shown in Table 1. In the first trial of the experiment the banana and bread were dropped for five seconds before performing the swab to check the quantity of bacteria collected. After 48 hours of storing the plates at room temperature, the first two banana drop tests on the bacteria contained too many bacterial colonies to count (Figure 1). We decided the bacteria was too many to count because the entire plate was covered in bacteria. Although we were able to count the number of colonies for the third banana run, 148 colonies, the average number of colonies present on the banana for all three runs was too numerous to count (Table 1). The bread colonies present on the plates are shown in Table 1. The average number of colonies counted for bread was 153 colonies (Table
