We encourage our incorporation of sustainable features as an educational tool. This is why we have also decided to participate in the 2009 History and Environmental fair in Topeka. There were roughly 30 exhibitors there to teach about 1,500 fourth and fifth grade students earth-friendly practices. Many of the students knew of last year's Greensburg project, the Sustainable Prototype, and were very interested what we were doing this year. We would like to invite all interested students to tour the finished house on May 16 at our open house.
