1. We firstly passed a slice of bread around the class, each touching it with unwashed or ‘dirty’ hands and sealed the slice of bread in a clear sandwich bag.
2. We then each thoroughly washed our hands with soap and warm water.
3. Next, we passed another slice of bread around the class, each touching it with our now ‘clean’ hands and sealed the slice of bread in a clear sandwich bag.
4. Mrs Tubby also placed a slice of bread which had not been touched into another sealed sandwich bag.
We are going to observe any changes to the slices of bread over the next week. We are particularly interested to see if we see any germs appear on the slice of bread we touched with our ‘dirty hands’.
