Audit 10 is the set for a whole class working in teams of three. It comes with the Schoolyard Heat Audit: students map the hottest and coolest places at their school, prove it with data, and present a recommendation. Where should the new trees go? Which side of the building needs shade?
It’s the same audit a school council, a parent society or a city can use, and the report template turns the class’s data into something they can hand to them.
