The short story, a science teacher from a not-so-wealthy school, wants to get his kids interested in science. His idea, take an issue even kids are aware of (the rising cost of fuel), and instead of preaching of the evils of Exxon or thumping for corn Ethanol, he introduced the kids to an alternative to both: Bio-Diesel from Algae. And to prove it works, one of the kids got his dad to donate a diesel VW van for an experiment that involves using the fuel the class made to drive to the Sears Tower and back.
He used a creative way to call attention to an issue, and instead of just prostelizing, he showed the kids how to use science and creativity to find a solution to a problem through the sweat of their own brow.
We need more teachers like this.
