AFM Model Activity Guide

This three-page activity guide, provided by the University of Massachusetts at Amherst, outlines a lesson for students grades 5-12 to create and use an atomic force microscope (AFM). Students use an AFM to "detect very small differences in depths or thicknesses." Intended for integrating into a the study of simple machines, this activity guide includes an introduction, instructions for teachers about how to facilitate this activity, classroom exercises, and a list of web resources that provide further information about Atomic Force Microscopy. Additionally, extension activities that expand upon the knowledge presented in the original activity are included at the end of this guide; they teach students how to analyze torque and the pathways of light
