Students in Ms. Meyer’s science classes last week learned first hand about the steps involved in the scientific method, while at the same time gaining practical knowledge about the importance of keeping their sandwich bread sealed. For this experiment, students used three slices of bread, designating one as a control, and then adding a liquid of their choice to the other two slices. Hypotheses were developed as to how long the bread would remain mold free and if the differences in the acidity of the liquid would contribute to mold growth. The conclusion was that all liquids, including the Florida humidity, contributed to the growth of mold on the sandwich bread. Don’t be surprised if your kids begin checking the expiration dates on your loaves of bread!!
