Some schools are crafting lessons with help from local universities and companies that work in nanoscience. That's the case at Ballston Spa High, located in an area of eastern New York known as Tech Valley, home to many technology firms and top-flight research institutions. By delving into nanotechnology, a specialized subject that is more commonly taught at the university level, teenagers in the 4,500-student Ballston Spa district not only gain an understanding of a rapidly advancing area of science, but also pick up skills coveted by local employers.
