This interactive presentation, created by Terry Bartelt for the Electromechanical Digital Library, discusses the rotations per minute (RPM) of AC motors. Bartelt begins with a discussion of the magnetism that allows most of these motors to function. The author addresses such factors as the frequency...

Module Description: This module, from Support Center for Microsystems Education (SCME), provides content and activities that allow the participants to locate safety data sheets, extract information, and compare the potential hazards of two or more chemicals. "MEMS (microelectromechanical systems)...

This webpage from the GeoTech Consortium of Western New York: Get the GIST (Geospatial Information Science Technology) Certificate provides sample GIS activities. These activities include a latitude and longitude lab, two topography and glacier feature labs, an exploring rock types using ArcGIS ...

These resources, provided by Northeast Wisconsin Technical College (NWTC), include information about NWTC manufacturing industry tours. To get students interested in manufacturing careers, NWTC typically has high school students visit two local manufacturing companies and then the Green Bay NWTC...

This resource, created by San Diego Bay Watersheds in partnership with San Diego State University, provides data about water quality in the Bay area. The site provides four different tutorials designed to introduce students or educators to the concepts of geographic information systems (GIS) as it...

The objective of this learning activity is to provide students with an introduction to the sand casting method for metals and with an understanding of how the properties of materials can be changed. Sand casting is used to "make parts that are comprised of iron, bronze, brass, and, at times,...

This presentation, published by the Center for Renewable Energy Advanced Technological Education Resource Center (CREATE), is part of a series that introduces learners to Supervisory Controls and Data Acquisition (SCADA) for renewable energy. The presentation explores Human Machine Interfaces...

This 9-page resource, from the STEM Guitar Project, is a math activity on scale length, frequency, and string tension. This resource provides some background information on string tension and includes a list of learning objectives, an activity description and directions, activity answers, and ten...

This lesson, presented by the National Nanotechnology Infrastructure Network, covers the general concept of scale by demonstrating factors of ten. The activity "facilitates the introduction and reinforcement of the metric scale and paves the way to the discussion of lengths that are smaller than...

This resource provides an introductory activity on scanning tunneling microscopy. As the module states, "a scanning tunneling microscope is a powerful tool for observing and manipulating the atomic-scale world." The activity covers concepts such as the tunneling effect, scanning the surface, two...
