Very few of these questions have accurately planned responses. I knew that we were going outside. That was basically it. In my head, things worked out great. Students paid attention, were efficient in cycling through their trial runs, wrote down everything they were supposed to, and celebrated. There were no celebrations, some kids "forgot" to write down their data, most were slow to bring their dolls up for trials, and some were off in la la land.
Even still, we carried on. Before we went outside, students laid their work onto their desks and I checked them for completion and (as much as I can for a class of 38) accuracy.
