My conclusion on bacteria in our school
I conclude that the door handles in our school carry the most bacteria in our school. The are in which we swabbed the door handle there are several colonies. In one area there is a big rough edged blotch of bacteria, there's also another area that almost looks like it was spray-painted on. On inaccuracy we had was where we swabbed the gum under the tables there's is a spot of bacteria growing out of the z-shape we swabbed. I learned that bacteria can form perfectly rounded circles and that they can grow in different shapes. I wonder why on the door handles area the bacteria didn't all grow in the same size/ shape and color something to look into next time I guess!
