Joel Makower (yes, yes, I know I link to all his posts) has a bit of a contest running. He received this query from a reader:

I am teaching a college course this semester on Sustainable Science and Technology and was wondering if you had any suggestions for a one-hour activity that would engage students to learn and possibly apply some of the fundamentals of sustainability.

He’s soliciting ideas and offering a nice prize for the best one. Go brainstorm with him.

Grist thanks its sponsors. Become one.
