Science investigation: Are germs really everywhere?  Thinking about hygiene.

Freshly cut potatoes were wiped on different surfaces and left in a plastic bag in the dark for a couple of weeks. After that time we could see evidence of germs. Although we could not see them before, we now know that they are everywhere. Perhaps we really should wash our hands properly! We discussed when it is important to wash and we carried out another experiment with lotion and glitter to show how germs could be spread from our hands.
