This week the children have been learning how to keep clean. We did a ‘hand wash’ experiment. We covered our hands with margarine and hundreds and thousands. (These were the germs and nasties.)
We tried to wash the germs and nasties off with just a towel but the germs and nasties were still there!
We then tried to wash the germs and nasties off with water but the germs and nasties were still there!
We then tried to wash the germs and nasties off with soap and water. The germs and nasties disappeared! We have learnt that we must wash our hands with soap and water if we want them to be really clean.
We have also set up another experiment. We want to see how quickly bread can go mouldy if we touch the bread with one pair of clean hands, with one pair of dirty hands or with 30 pairs of hands. Which do you think will go mouldy first? Why?
In activity time we had lots of fun putting different germs and nasties onto hand prints. Some germs and nasties were made with tea leaves, some with coffee beans, some with leaves and some with sand. Can you guess which one is which?
