Scenario: Maria wondered if different colors of plastic wrap affected the time for bread to mold. She wrapped a slice of bread in clear plastic wrap, blue plastic wrap, and red plastic wrap. Before wrapping the bread she placed 5 mL of water in the center of the bread. The bread came from the center of the same loaf. In each case, she used the same amount and same brand of plastic wrap. She wrapped the different slices of bread in the same way. What is a good title for this experiment?
