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. Before wrapping the bread she placed 5ml of water in the center of
the bread. She repeated the process with a slice of bread using red plastic wrap & a slice of bread using
blue plastic wrap. The bread came from the center of the same loaf. In each case she used the same
amount of water and the same brand of plastic wrap. She wrapped the different slices of bread in the
same way.
