Nanoscience refers to the fundamental study of scientific phenomena, which occur at the nanoscale--nanotechnology to the exploitation of novel properties and functions of materials in the sub-100 nm size range. One of the underlying principles of science is development of models of observed phenomena. In biology, the Hardy-Weinberg principle is a model for predicting alleles. In physics, a particle subject to constant net force is a model in mechanics that governs bidirectional and projectile motion. In chemistry, the particle model for gasses has been used to explain gas behavior. A concrete and perhaps even tangible representation helps students grasp complex relationships and construct new knowledge. As students are increasing their abilities to understand abstract concepts, it helps them if some concrete modeling are provided. Such activities help students build their understanding through laboratory experiences and concept construction. In this article, the authors discuss nanoconcept materials developed around a key measurement device of nanoscience, the scanning probe microscope. (Contains 4 figures.)
