Key Info
  • Bacteria and healthy living
  • The Rot Box detectives find out about both good and bad bacteria, and learn about the importance of hygiene to prevent the spread of bacteria from one person to another. Special UV cream, which cannot be seen in ordinary light, is used to show how bacteria spread. With cream on their hands the Rot Box detectives shake hands, then using UV light they can see how easily the cream (bacteria) can be passed from person to person. Using disclosing tablets the Rot Box detectives are also shown how even after brushing, bacteria are still on teeth. The bacteria live in the film that forms on our teeth called plaque, the bacteria feed off the sugar that is in the foods that we eat and then produce acid which can rot our teeth.

Ideas for use in class
  • Ask children when and why they need to wash their hands and clean their teeth. Put some green hair gel (representing germs) on the hands of a few children in the class and tell them to shake hands with everyone else. Then tell the children to put their hands up if the germs (hair gel) have been passed on to them. Ask the children to think about how they could prevent germs from being spread e.g. washing hands, using a handkerchief. Ask children to think about what each one of them could do to prevent the spread of germs and also to stop plaque developing on their teeth.
