Micro-organisms

Crawling through a giant nose in the Secret Life of Snot may have inspired you to make your own 'sneeze gun' and use it to investiagte how far a sneeze goes, a sure way to engage children in an investigation to see how viruses spread.  In Plaque Attack! bacteria are given the brush off. You can explore the effect of microbes on teeth with these comic strips, powerpoints and investigations looking at keeping teeth healthy. Or why not a class project to develop a toothpaste which counteracts the effect of sugary drinks on our teeth.
