Earlier this week, when the temperature during my prep period was in the 30s, I noticed no "roamers", no students in the halls during class time. (For those of you *not* from California, we don't have many "indoor" schools here. Our classroom doors open to the outdoors.) Today, the temperature could have been in the low 50s--and the roamers were out.
I wonder what the temperature cutoff point is at which students would rather stay in class than wander about.
