As part of our Topic on Living Things, Class 3 have been learning about microorganisms. We were lucky to have a visit from Helen, a scientist who specialises in studying bacteria. She taught us lots of interesting things about harmful and helpful bacteria. She brought some bacteria in for us to look at. We couldn’t see it but we could see the trail it had left in the Petri dish! She also showed us some fruit flies munching on mushy banana. A bit disgusting but very interesting!
