Self Assessment

Here is an situation given to pupils which involves micro-organisms, decay and disease.

They are asked to explain what is happening.

Alexander's mum finds some left over chicken in the fridge.

 

So, she makes chicken sandwiches for his packed lunch.

It is a lovely warm summer's day, and when Alexander gets to school he puts his lunch box on the window sill.
At lunch time he picks up a sandwich, smells it, and says "yuk! this chicken's gone off."

What do you think is going on inside the chicken to make it smelly and no good to eat?
