Year 6 children investigated how bacteria can be spread after sharing a ‘sneeze’ ( white liquid) and then shaking hands without washing them. Under the ultra-violet light the children could see how the sneeze had been passed on to their hands. After hand washing the children checked their hand again and were surprised to see their hands were still not ‘sneeze’ free. A very good exercise in hand-washing as well as finding out how easily bacteria and germs can spread.
