In year 4 science lessons, we have looked at how germs spread and the importance of washing our hands. We got two pieces of bread and we took the first slice outside. When we were outside, we dirtied our hands and rubbed our germ filled hands all over it! We also dropped it onto the floor to gather more dirt and germs. We then placed the germ filled bread into a sealed plastic bag.
On entering school, we washed our hands correctly with water and soap to remove the dirt and germs. We collected another piece of bread and touched both sides with our clean hands and placed that into another sealed plastic bag. We left the bread for a week.
As you can see the germs had spread on the dirty bread and it had turned a greenish blue with yellow speckles.
Ellie said, “It looked like it had fury bits on it!”
Isaac said, “The bread looked disgusting and gross and I would not eat it now.”
May said, “We all learnt that we should wash our hands to stop the spread of germs and this links with stopping the Coronavirus spreading!”
The pictures below show how important it is to wash our hands to stop germs spreading!
