So... Just How Dirty is Mrs. Owen's Classroom??



The students got to test the classroom yesterday to see how much bacteria is actually growing in there (Mrs. Owen probably doesn't want to know the results of this activity!) Within their groups they tested different surfaces around the room. One person in each group squirted hand sanitizer in their petri dish to see if it really does kill bacteria the way the commercials say.

We will let them sit in a warm, dark place for the week and see what grows!
