- bread
 - hand sanitiser
 - handwashing liquid
 - water
 - various communal classroom items (e.g. ipad, pencils, etc)
 - gloves
 - sealing sandwich bags
 
- Teachers handed the bread with gloves.
 - One student washed their hands well for 20 seconds, following the display posters. They then wiped their hands on a piece of bread and it was placed in a labelled sandwich bag.
 - One student used hand sanitiser and then wiped their hands on a piece of bread.
 - One student did not wash their hands at all and wiped their hands on a piece of bread.
 - Then we wiped a piece of bread on an iPad and whiteboard pens.
 - We left the sandwich bags for two weeks and then looked at the results.
 
I only got a picture of the pieces of bread that grew nasties but it proved our point and was certainly a conversation starter!
Have you conducted any experiments to show the importance of hand washing?
