My hypothesis for this experiment was “If the mold is placed in open air, then more mold will grow compared to placing it in a sealed plastic bag, because mold won’t be able to grow because there won’t be oxygen.” I proved my hypothesis. In the lab, we contrasted the amount of mold growing on a slice of bread that was left in open air, compared to a slice of bread that was inside a bag. Our control was the bread placed inside the bag, and the other was left in open air. We observed them, and a few
