Not to freak y'all out, but did you know that germs are on everything you touch? Using a special powder called Glo Germ (get it here) you can actually see how germs spread from one thing to another. It will make you want to wash your hands more often. (And the CDC recommends washing your hands frequently. In fact, why don't you go wash up right now?)

Scrub 'em: Use soap and water, and wash for 20 seconds. That's about the time it takes to sing the "Happy Birthday" song twice.

TRY THIS:
Goal: to observe how germs are spread
Age level:: 3 and above
Activity time: 2 - 5 minutes
Prep time: 5 minutes

Materials needed:

  • Glo Germ powder
  • Toys or common household/school/office objects to "spike" with germs
  • UV lamp or detector box

Preparation:

  1. Sprinkle Glo Germ powder on your objects.
  2. Arrange them somewhere where others can handle them.
  3. Plug in UV lamp, but don't turn it on.

Directions:
Encourage others to pick up and play with the objects. Ask them what they know about germs.

  • Do you know where microbes are found?
  • Do you know what a microbe/germ is?
  • Do you know what illnesses are caused by germs?
  • Do you know the best way to avoid getting sick because of germs?

After the discussion, tell them that, as part of an experiment, you've put "pretend" germs on one or some of the objects they may have touched today. Switch on the UV lamp: what glows?

Reinforce the fat that the Glo Germ powder is just to simulate germs. It won't make you sick. You can get rid of the germs by washing your hands. In fact, encourage your audience to wash their hands and then hold them under the UV light again.

(On the other hand, remember that not all germs are bad. Exposure to some germs is thought to protect people against asthma and allergies or colitis, and overuse of antibacterial products leads to antibiotic resistance and superbugs as well as potential damage to the environment.)

Well, some things are starting to make sense now.
