Hand Hygiene

Date: 6th Mar 2020 @ 2:07pm

We used vegetable oil and cinnamon (and a very enthusiastic Mrs Crelin) to investigate how long was needed to wash our hands thoroughly. The cinnamon repsresented the germs left on our hands after rinsing with no soap and just water. We found it would only come off if we used lots of soap and washed our hands for around 20-30 seconds. Even after this time there were tiny amounts of cinamon left over. But we discussed how some microbes can be harmless and useful to our bodies.
