"We started simple. We sampled leaves and considered when they turn green. We reflected on the way a tree is similar to and different from a human body. We sampled the classroom. And then we swabbed the classroom for bacteria. The students chose where to swab. The teacher, Mrs. B., was swabbed (belly button, shoe, etc…), the floor too, as were a backpack, the soil outside, a flagpole outside, a flagpole inside (flagpoles seem to be a conspicuous feature of the elementary school day), the computer table, a lunch box and a trashcan. I was also swabbed. The students then generated hypotheses about where we might find the most kinds of bacteria. This bacterial work was not yet science; it was outreach—showing the students’ results that exemplify what we already know—but in this context we could still walk through the steps of science. We could generate hypotheses and consider them in light of what we found."
