I tested my hypothesis by taking samples of bacteria from the feet of a chicken, a human, and a rabbit, placing them in augers, and recording their growth over three days. I used a culture mix, water, a stove, a pot, nine petri dishes, graph paper, and samples of bacteria in my project. The full procedure went like this. I first mixed the water and the culture mix, then boiled it, and added some to each of the petri dishes. Then I pressed the feet of each of the animals on three of the cultures. Next, I recorded the size of the bacteria.
