Germs, Bacteria and Viruses, oh my!

Suitable for early years and KS1

Good personal hygiene is essential to keep us healthy, but as we all know, young children have trouble with this, particularly not washing their hands correctly. This session is aimed at younger children and aims to illistrate what happens if they don’t wash their hands correctly. For early years we have a very brief talk before giving the children a special gel that “shows” the “germs” on their hands, using a UV light. Once they apply the gel their hands glow. They then wash their hands and we check again, showing any areas of their hands they have missed.

For the older children we have a similar talk but instead of using a gel on their hands we give each child two agar plates. They place their hand on the first plate, transferring any actual bacteria or fungus on their hands, they then wash their hands and touch the second plate with their clean hand. After a few days they should see bacteria growing on the first plate and (hopefully) nothing growing on the second plate.
