Recently Jaralee Metcalf, a behavioral specialist and her colleague found an experiment on the C.S. Mott Children’s Hospital website, called “How clean are your hands?”
“We chose this experiment because we had been learning about decaying leaves and mold and flu season was approaching,” Jaralee Metcalf told. “We decided it would be an awesome mold experiment to learn about germs by using moldy bread!”
The mold that formed from the Chromebooks
Here’s the untouched slice of bread
The one that was touched by kids with dirty hands
The slice that was touched by washed hands
And the one that was touched by kids who used hand sanitizer
