Almost two weeks ago Team 4 started an experiment to look at if cleaning our hands decreases the amount of germs on our hands. To test this we got three pieces of bread. One piece we put in a bag using tongs. Another piece we all touched with dirty hands and put in another bag. And the last piece of bread we touched after washing our hands then placed it in another bag. We have been waiting patiently to see mould growing on the bread. We predicted the bread that had touched our dirty hands would have the most mould.
Unfortunately, it is now Science Week and our bread still has no mould! We talked about how sometimes experiments don’t go to plan. It also made us question why the bread hasn’t started going mouldy yet. We then learnt about what preservatives are and what they do when put in our food.
Fingers crossed that we will see some mould soon!
