About 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.

"The mold experiment was very cool and kind of gross," reported one classroom participant.

Moldy Bread

The mold in this picture came from the piece of bread shown above (top right corner). It was touched by a student's hand before being placed in the bag. For more on the experiment - read the column at the left.

During the 2002-03 school year, more than 1,900 students in 104 Lincoln classrooms experienced an average of 11 hours of nutrition instruction through the NEP School Enrichment program. Teachers say, "We tripled the amount of time we spent teaching students [nutrition] from four hours to 12 hours."
