In science we have been learning all about ourselves and our bodies. We also learnt why it is important to wash our hands with soap and water. A parent brought in a special machine so we could test out whether we were washing our hands correctly. First we put a special germ gel onto our hands and rubbed it in between our fingers. We then had to wash our hands thoroughly with soap and water to clean all the germ gel off. After that we placed our hands under a fluorescent light to see whether we got rid of ALL the germs. In these pictures, you will see that the parts of the hands showing white are the places where germs still exist. The result of this investigation was that we are all going to use more soap and water next time.
