Help kids learn for themselves WHY hand washing is so important with this simple experiment.
This experiment will show why you should always wash your hands before handling food. Using sliced bread, you’ll see how much mold grows after you touch the bread with dirty and clean hands. How different do you think they’ll be?
3 slices of bread*
3 (or more) resealable plastic sandwich bags
* Any kind of bread works, but store-bought white bread contains preservatives, which will slow down the growth of mold. For best results, use preservative-free wheat bread, bakery-fresh white bread, or homemade bread.
Note to adults: This activity involves growing mold on slices of bread. Once sealed, the plastic bags should not be opened. When the experiment is finished, throw the bags of bread away.
