What a great step by a public school! One thing I would definitely teach is something that seems obvious but is definitely not obvious to modern kids who did not grow up spending all their free time outside in the woods: how to walk outside. E.g, how to climb a rise by traversing across the slope, how to choose your footfalls when in rough terrain, especially going downhill, how to safely get over / under/around a fallen log, a fence, a thorny thicket, a stream. Every year in western NC, we lose teenagers and young adults with plenty of tattoos and piercings but not a lick of sense about respecting slippery rocks, current and gravity at the top of waterfalls.
