Monitor whether outside doors and windows are closed during cold weather

Getting the temperature right in the classroom is important; too hot and everyone falls asleep and doesn’t learn, too cold and we shiver, and must put extra jumpers on.  Sometimes teachers open windows or doors when the classroom gets too warm and stuffy during  the winter months. Instead we should try to turn down the heating to reduce energy use and save the school money. Opening windows or doors means we are letting all the heat out of the building, and wasting money.

Pupils can complete this activity to identify where heat is being wasted in school.  Are thermostats and radiators turned too high?
