Most students learn at an early age that everything is made of atoms and that atoms group together into molecules. Molecules can be crystals, polymers, proteins or cells. The aspect of nanotechnology that is critical for understanding materials is that the order and/or arrangement of the atoms into molecules and molecules into objects defines the electrical, physical and biological properties of that material. If we observe a unique property of a particular material it is because the molecules /atoms are arranged in a specific manner -- change the arrangement and we change the property. For example, carbon atoms arranged in one manner comprises pencil lead, arranged another way it is a charcoal, arranged another way and it is a diamond. All of these objects are comprised of the same materials, carbon, but each has unique and distinct properties. These modules will enable students to study different materials and their associated properties.
