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...

This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty members Terry Bartelt and Stephen Schneider, introduces air leaks in pneumatic systems. The lesson, full of illustrations and animations, walks students through the cost and cause of...

This learning object examines pneumatic directional control valves in two-way, three-way, and four-way valves. The presentation is interactive, as it allows the user to focus of certain valve types and cater their learning towards those. The site employs flash based animations, and also many other...

This interactive lesson, by Electromechanical Digital Library and Wisconsin Technical College System faculty member Terry Bartelt, discusses the three types of air preparation processes for pneumatic systems: filtering, regulating, and lubricating. Each method is discussed in detail, with...

This brief interactive activity, by Electromechanical Digital Library and Wisconsin Technical College System faculty member Terry Bartelt, begins with a discussion of the three basic components of a pneumatic power system, the prime mover, compressor, and receiver tank. Visitors can learn about each...

This animation, presented by the Maricopa Advanced Technology Education Center (MATEC), provides an overview of pneumatic valves and pneumatic cylinders. According to the animation, "pneumatic valves control the flow of compressed air" and have "two common features: a passageway through which air...

Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA. This animation from Cold Spring Harbor Laboratory's Dolan DNA Learning Center presents...

This lecture series, from the Howard Hughes Medical Institute Biointeractive project, features the following lectures: "Understanding Embryonic Stem Cells," "Adult Stem Cells and Regeneration," "Coaxing Embryonic Stem Cells," and "Stem Cells and the End of Aging." Each lecture, available in Flash...
