A "Hands On" Experiment

Before the cold and flu season started, we did a little experiment. I washed my hands and touched the 'Clean Hands' piece of bread and put it in the bag. The students passed around the 'Classroom Hands' slice and then placed it in the bag. The bags were then placed in the closet and we waited. And waited some more ...(because the bread had preservatives in it, this took a bit longer than we all thought). I think the results speak for themselves and really show the importance of proper hand washing with soap and warm water.
