Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. This simulation of a Gas Properties is from the Physics Education...

Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.This simulation of a Resistance in a Wire is from the Physics Education Technology...

The interactive resource, presented by the University of Colorado, Boulder, presents a demonstration how a doped semiconductor to create a diode or transistor. Watch the electrons change position and energy. This interactive simulation has a teacher's guide and an ideas and activities section.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it. This simulation of a Signal Circuit is from the Physics Education Technology website of University of Colorado. Included are links...

In this video from the ICT Center, learn about fiber optic receivers. Investigate the components of an optical receiver; how a photodetector converts an optical signal to an electrical one; and the characteristics of PIN, avalanche, and metal-semiconductor-metal photodiodes. The video runs 2:07 and...

In this professional development video from Getting Results, natural resource technology instructors at a community college discuss fitting their courses together. The instructors say that clarifying and communicating outcomes helps them plan courses. They can reinforce skills taught across the...

In this media-rich, self-paced lesson, students explore the range of industries that produce and rely on advanced technology and learn how their skills and interests may align with career opportunities in this cutting-edge sector. The lesson contains videos that feature professionals describing...

This video, presented by WGBH, looks at a high school outreach program to get students interested in plastic manufacturing by having them make plastic race cars. The students go through the entire process of design from both technical and hands-on perspectives. This video also serves as an overview...

This learning object covers cylinders and motor pneumatic actuators. It is hosted by the University of Wisconsin-Madison and consists of cylinders operations such as: single, duel acting, factors for cylinder speed. The program require Macromedia Flash player, and presents a very nice overall...

This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty members Terry Bartelt and Stephen Schneider, introduces pneumatic air conservation. The lesson begins with an illustration comparing production of air force by electric and pneumatic...
