The National Center for Learning and Teaching Nanotechnology (NCLT) based at Northwestern University is developing “nanoconcept” materials to bring nanoscience into the classroom. These materials center around key new concepts in nanoscience, including surface-area-to-volume ratio and the dependence of the nature and properties of matter on size. This article discusses nanoconcept materials developed around a key measurement device of nanoscience, the scanning probe microscope (SPM), and presents a two-week long series of nanoconcept activities—culminating with a design project in which students build their own SPM model.
