Atomic Force Microscopy

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.

Each Kit Includes:

• 1 LASER Guided Topographic Visualization Unit (plastic box)

• 2 bags Legos® Molecular Building Blocks (each bag containing six 1.25”x1.25” and two 1.25”x 2.5” pieces)

• 1 Molecular Mounting Plate (Legos®) 5”x5”

• 1 Dowel Rod Probe -red LASER pointer, line level, rubber bands

• 1 Wooden Projection screen (cards) holder

• 10 Projection screens (cards with lines)

• 1 Perforated lid to plastic box

• 1 Scissors

• 1 Ruler
