This past Thursday (8/27/2009), The Wall Street Journal contained an interesting story (currently subscriber content) on the current downturn in the biofuel market. It was quite good and if you poke around using your browser, you might find most of the text in one or more sites.
What I found interesting were the various economic concepts that were illustrated in the story. I played with it a bit and came up with a PowerPoint® presentation that uses various quotes from the story and relates each one to basic ideas in economics - some with simple graphs to demonstrate them.
I'm interested in finding out whether this type of presentation would be helpful to classroom teachers. As a result, I will send a copy of the presentation to the first 25 high school teachers who reply to this post and request a copy. However, I will request three things: your name, the school you teach at and its location, and your analysis of the presentation. Let me know if it would be useful for your class or not. If not, why not. I'd be most grateful.
