Bio blog

In biology we have started our microbiology unit. We started by collecting soil, to look at the bacteria in it. We also went around the school to see how much bacteria are around the school, like door handles, and hand rails on the stairs. We looked at bacteria from our nose, ear, and tongue. There was only one colony of bacteria for the ear, because Kael had cleaned his ear out that day. But there was lots of bacteria for the nose, and the tongue. At the beginning of the unit a petri dish was passed around and we all touched it and lots of bacteria was on it, despite washing our hands twice.
