PHYSICAL SCIENCES (Grades 9-12)
Topographic imaging at the 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.
