Here is a fun eye-opening activity to teach children how germs spread. First of all pretend to sneeze. Then dip both hands in washable paint. Walk around the room touching different items. Have the children notice how everything that was touched has been painted. This is how it is when one’s hand has germs on it. Every time you touch an item these germs are passed from one thing to another. Have the children find each spot, counting and cleaning it up explaining to them how when we wash our hands properly this prevents the things around us from becoming “painted” by harmful germs that can cause sickness.
