moldy bread
Lindsey baked bread for a bakery. She stored her bread in clear bins in the back of
the bakery, but she sometimes found mold growing on the bread. Lindsey wanted to
know if exposure to light affects mold growth. She predicted that less mold would grow
on her bread if she stored it in dark bins. For two weeks, Lindsey stored half of her
bread in dark bins and the other half in clear bins. She found that the same amount
of mold grew on bread in both types of bins. She also noticed that bread in bins
stored closer to the oven had the most mold. Based on her experiment, Lindsey
determined that light did not have a major effect on the total amount of mold that
grew on her bread. Lindsey thought that temperature might affect mold growth and
that less mold would grow on bread stored in cold conditions.
