Let's face it: Kids in close quarters like classrooms are going to spread all kinds of germs to one another, right? Probably, but when you encourage healthful habits, kids tend to miss less school because of illnesses they've passed on to one another.

It seems like such a simple lesson, and it is, but it goes a long way in killing germs. Ask the child to sing the Happy Birthday song twice to himself as he scrubs hands - the tops, palms, fingers, and in between.
