KS4 have been learning about food safety and hygiene this term. To demonstrate the importance of washing your hand-especially before cooking, we have done an experiment to see whether or not washing our hands really does reduce bacteria and germs.
First we filled out our experiment prediction worksheet. Then we pressed our unwashed hands into a piece of bread.
We then washed our hands and did the same thing again with another piece of bread. We then sealed our pieces of bread in a clear zip-lock bag.
We will open our bags and observe the results next week. We will then complete the Conclusions section of our worksheet. Most of the boys predicated that mold would grow on the piece of bread that they pressed down on with their unwashed hands-some thought it may even grow mold in the shape of their hand! We will have to wait and see!
COME BACK SOON FOR OUR RESULTS AND CONCLUSIONS!
