At Beaver Falls High School, Tim Liller teaches technology education, or the class typically thought of as "shop."
Once a staple of high school education, shop class has fallen by the wayside with the decline of American manufacturing. But here, Liller's students still learn the basics, including how to wire a home and fix small engines. And more recently, they've also been learning how to make solar panels and build hydro and wind generators.
These are skills Liller hopes they can build on when they graduate.
