My youngest sister is homeschooled with three or four other kids... they are about high-school-sophomore level. I'm kicking around the idea of teaching some kind of oil depletion/current events/relocalization unit to them (a one- or two-day, one-off kind of thing). I'd like to start with a brief intro to the concept, some brainstorming of things they've noticed around them, some scenario-building, and then end with things they can do personally.
They live in Flint, Michigan, so info relating to GM and already economically depressed communities would be relevant. They're also Seventh-Day Adventist, so doomerish scenarios will not easily freak them out. Do you folks know of any PO teacher curriculums, or material that would be useful for this?
