In science year 6 have been investigating microbes. We found all sorts of microbes lurking around school. We used cotton buds to swab handles, bannisters, pond water, specs, etc and pressed the buds onto plates of agar jelly. We left one section of the plate with nothing added. This was our ‘control’ and acted as a comparison.
Here are our plates of nutrient agar after two weeks.
Now you know why were always on at you to wash your hands before tea!
