Claim

ehickam29 — 2025-08-14 14:49:14 UTC

The source with the most bacteria is the gym floor. My claim was right and the gym floor had the most bacteria by a large amount.

Reasoning

There is more bacteria located on the gym floor because it is in a warm, moist place, with high traffic. The gym floor comes in contact with more bacteria that any other spot in the school. This gym has a lot of human contact from sports, outside audiences, and gym classes. Athletes also sweat and have bodily fluids on the floor. People carry bacteria on their skin and every time an athlete touches the surface it spreads bacteria. All these reason justify my claim that the gym floor has the most bacteria.

Evidence

I know that the gym floor has the most bacteria because the contact plate had 56 colonies. This part of the contact plate had the most bacteria by fair. On the bar graph you can tell that the gym floor had the most bacteria because it had the highest bar on it.
