Germs!

Cut confetti out of various colors of construction paper and stuff in into an uninflated balloon. Blow up the balloon and have a pin ready. Pretend to sneeze and at the same time pop the balloon. The confetti or "germs" will fly all over the room. Explain to the children that it is similar with germs when you sneeze. If you don't cover you mouth and nose with a tissue then the germs go all over everyone and everything. Have the children look at how far the germs went. As a transition to wash their hands, sprinkle glitter or "germs" onto their hands and have them scrub until they are all off. It helps them to understand that germs hide in between their fingers and it sometimes takes a while to wash them all off.
