In science we have been looking at the discovery of germs, how they are spread, and how to prevent them spreading. We used a 'germ' lotion and a UV light to show germs that could still be on our hands after using different methods to wash them. We found that the method that removed the most germs was using warm water with soap, over cold water or just warm water on its own. We then used our findings to create posters advising people to wash their hands effectively!
