The student teacher looked up and caught sight of the clock; the change of classes loomed like an approaching storm. “I’m coming around with the trash can,” he said. “Please make sure you throw everything away, I don’t want to see any owl pellets left on the desk.” The students, who had been working attentively, dutifully gathered up the tiny fragments of bone and fur, and used a sponge to wipe down the tabletops. Watching from the back, it was all I could do to stay in my seat. Rarely had I seen such fantastic teaching in an urban science classroom, particularly with so many English language learners, and it broke my heart to see the lab come to such an ignoble end. It felt as if a world-class chef had prepared a meal in front of me, and then tossed most of it into the garbage.
