Those Germs Away!
Love That Teaching Idea! Staff
Submitted: March 31, 2001
I do a unit on germs and sickness, I can't let it go by without
doing the hand-washing test! I invite an employee from the local
health department to come in and talk to my students about the
importance of hand-washing in preventing illness. I am sure to
ask him to bring in his fluorescent lights where students can
wash their hands on their own and then place their hands under
the lights. Wherever there are remaining germs on the hands, they
will show up under the lights. My students are bewildered because
they thought they had already washed away all their germs. But
the children learn that simply rinsing your hands under water
or washing for a few seconds, just does not cut it. So this fun
experiment is a real eye-opener!
