I ran across this piece on the MSNBC site. You may have seen the reports when they aired. Nevertheless, as we settle in to watch our favorite teams compete in the NCAA or NIT tournaments, you might want to consider how the impact of the corn-for-ethanol program on other agricultural commodity prices is impacting consumers as they pick up the phone for delivery, settle into a favorite neighborhood sports-viewing venue, or otherwise get ready for tournament festivities. It does a good job of bringing the impact of larger economic issues down to the pocketbook level.
The videos on the site are also quite good - but the one on pizza is perhaps the most relevant for your students. I personally would not use the beer video in school.
I look forward to your comments.
