Are our hands clean?

Lesson: Science

Class: Year 1 Year: 2019 - 2020

On Monday 18th November, Mrs Ali and her colleague come into school and talked to the children on European Antibiotic Awareness Day. They spoke to us about the importance of washing our hands and coughing/sneezing into tissues and throwing them away. They told us that the bugs that make us poorly are becoming cleverer and our antibiotics are starting to not work on them. This means we need to make sure we do everything we can to stop spreading our germs.

Before we went to the hall for this activity, Miss Hey asked us if we thought our hands were clean. We all thought they were. She gave us a slice of bread and we passed it around the class so everyone had touched it. She then put it in a zip-lock bag and labelled it 'touched'. She also had another piece of bread she had already put in a bag. She didn't touch it when she put it in the bag. We checked it everyday and nothing happened. Then on Monday, we saw a little green dot on the touched bag. Today that little green dot has spread!

This has shown us that our hands weren't really clean. Even though they looked clean, there were little germs on them, which have caused the mould to grow on the bread. We spoke about how this mould is dangerous and can make us poorly. We spoke about how it is important to wash our hands before we eat so the germs that we put on that bread won't be on our sandwiches and go into our bodies. You can see how much mould has grown on our bread below!
