Part of Lesson Plan: Hand washing
Activity Overview / Details
Rubber chicken, other items to pass, Glitter Bug powder, blacklight stick, extension
cord, telephone, an apple or other fruit and a sandwich
1. Prior to arriving, sprinkle Glitter Bug Powder on rubber chicken and other
items including handouts. Rub on well so it is invisible. Pass items around the
room for all to touch without telling them about the Glitter Bug powder.
2. After all have touched the items, tell them that the items had fake germs on
them that will glow under blacklight.
3. Turn out lights and take ultraviolet light around room or have participants
come forward to observe their hands under the blacklight.
4. Use the blacklight stick to trace the “germs” from the objects to their hands,
face, tables etc.

After using the toilet and toilet paper and then not washing hands, you may have
bacteria on your hands. Then pick up a sandwich. Again, where do the germs go?
You ingest them. That’s what makes you sick – also touching your
mouth, nose or eyes gives the germs a way to get inside your body.
