The bread test

With the rise of talk about germs, bacteria and hand hygiene and the coronavirus, 2nd and 3rd class decided to carry out 'The Bread Test', to investigate areas with bigger amounts of bacteria. 
We tested five different bread slices 
1 - fresh from packet, untouched 
2 - bread slice rubbed on door handles 
3 - bread slice touched by hands that were washed with soap and water, while singing happy birthday twice 
4 - bread slice touched by hands cleaned with hand sanitiser 
5 - bread slice touched by 'unwashed hands'.
