This YouTube video, created by Southwest Center for Microsystems Education (SCME), provides an overview of the concept of scale, including micro, nano, and macro scales. It runs for 14:28 seconds, and compares "compares...

This lab, presented by the National Nanotechnology Infrastructure Network, introduces students to the difficulty to of measuring at the nanoscale. Accuracy and precision are the most important principles or measuring at...

This simulation provides practice on estimation of relative sizes. The user must estimate the relative lengths, areas, or volumes of objects. This activity builds student abilities to understand ratios and the scaling of...

This page, authored by Rod Nave at Georgia State University, describes units of measurement, unit conversions, dimensional analysis and basic mechanical quantities. Length, Mass and Time link to separate pages that go...

This lab, presented by the National Nanotechnology Infrastructure Network, introduces students to the concepts of scale and magnification using a Scanning Electron Microscope (SEM) image of a Blue Morpho butterfly wing....
