Microbes Around School

Microbes around school. As part of a CREST Award some of my students swabbed different surfaces around the school, grew the microbes on agar and recorded their results. This presentation can be used as a starter or plenary activity. I usually print off pictures of the eight different surfaces and get students to work in pairs or small groups to try and order them in terms of number of microbes. We then discuss the results and relate them to the standard of cleaning around the school.
