Abstract Topographic imaging at molecular level involves an indirect mapping of the surface of a material with a probe that follows the shape of the surface. In this activity, each team of students will use a simulated topographic scanner with a platform mounted laser probe to attempt to discern the structure of an unknown block of Legos built by another team. At the conclusion of this activity, students will be asked to apply the knowledge gained to develop an understanding of the atomic force microscope. Appropriate Levels All High School Physics. Time Required 2-3 40-minute class periods. |
