Conclusion and Analysis

The findings do not support our hypothesis; we hypothesized that as the temperature the E. Coli bacteria was exposed to increased, less colonies would be able to grow (while more colonies would grow as the temperature decreased), however, our results showed otherwise.

The variable we tested was the temperature that E. Coli was exposed to, which would help us determine the dependent variable, or the amount of growth of the E. Coli bacteria. Our data exhibits that at 16C, the average number of colonies grown was 225, at 22C the average number of colonies grown was 104, and at 37C the average number of colonies grown was 176. This led us to realize that the E. Coli bacteria grew more colonies at the lowest tested temperature (16C, 225 colonies) relative to the higher tested temperatures (22C and 37C); however, comparing the average number of colonies grown at 22C and 37C, it can be recognized that more colonies were grown at 37C (176 colonies) than at 22C (104 colonies). These results could have come out the way they had due to errors in the experiment. But from the results, it can be concluded that the temperature that yields the least amount of growth of E. Coli is between 16C and 37C, but compared to 37C, E. Coli grows at a faster rate while being exposed to 16C.
