Uma excelente ideia que pode perfeitamente ser aplicada na escola, principalmente no pré-escolar e 1º ciclo. O post Professora descobriu a maneira mais “nojenta” de pôr os miúdos a lavar as mãos aparece primeiro no ComRegras.
To all my teacher friends this is the grossest yet coolest experiment. I did this while teaching about germs and how they spread. You use three pieces of bread. You let all the kids see you put a piece of bread in a baggy with a glove on hence “controlled” then you wash your hands and put a piece of bread in a baggy for “clean” last but definitely not least you pass a piece of bread around and let every kid in class touch it then you put it in a baggy and label it dirty. Watch how the bread changes over time due to germs. It is so cool and a great way to teach the importance of hand washing.
