Moldy Bread experiment is part of the 4th grade Nutrition
Education Program's (NEP) School Enrichment kit, "Rate
That Plate!". In this experiment, students learn
the importance of the proper handling of food.
the Experiment: Four pieces of bread are exposed
to different conditions: one is not touched, one is
wiped on the counter, one is exposed to air for five
minutes, and one is touched by students' hands. The
bread is slightly moistened, sealed in bag and kept
in a dark, warm place. Students then observe the bread
for three weeks and draw conclusions regarding why the
different conditions caused different mold growth. They
also discuss the importance of washing hands and counter
tops before handling food.
