Warning: what follows may trigger, in some students, a sudden urge to stare out the window (but for good reasons). Because ESD isn’t a green punishment, nor a collection of “good habits” to recite between two multiplication tables. It’s an investigation: learning to notice the living world (even in a schoolyard made of asphalt), to ask the kind of questions that scratch, to check rather than simply believe, and to act without imagining yourself responsible for the state of the planet (they already bear the responsibility of the marker drying out without its cap). In short: a compass for growing up in a changing world… without losing your bearings or your blackbird.
