Scanning Probe Microscopy: "Feeling What You Can't See at the Nanometer Scale" (Elementary, Middle, and High School curriculum lesson)

Linked product
Description
Students simulate the function of a scanning probe microscope.This activity works best in groups of 3 students. Scanning Probe Microscopes (SPMs) of various types trace surface features by movement of a very fine pointed tip mounted on a flexible arm across a surface. SPM enables resolution of features down to ~1 nm in height, allowing imaging of single atoms under ideal conditions. In this activity, students will use their index finger as a probe to scan unseen objects.
