As we near the end of the semester, Physics 131 is once again finishing up with a unit on the statistical interpretation of entropy (not a typical topic for an introductory algebra-based course). This unit gets started with two labs: one systematically playing the famous Monty Hall problem and a second models the free expansion/compression of a gas using coins. While I do not have strong evidence for this belief, I feel that these two labs are the strongest two labs we do all semester. Students seem to really engage with these two labs and the act of doing the experiments really seems to add to student understanding in ways I do not see with other labs in the course. Even our much celebrated lab investigating the bio-mechanical ground-reaction forces of the human jump doesn’t seem to engage our students as much. Why? What is the “magic sauce” of these two labs? How can we modify the other labs of the course to achieve these same ends?
