Most of our class time today in Chem 9 was spent building boats and following an only slightly edited version of this activity. In the morning, many students noted wearily that they had built boats to float pennies many times (even multiple years in middle school). I promised them that this activity would be different from what they had done before, but they didn’t believe me until we actually started.
One class was able to have a short board meeting at the end, and the other class will do that on Tuesday. We talked a little bit about measurements, but we will talk about them even more when we wrap up the activity and move on to problems (and density, finally!) next week.
