The North Carolina Community College System BioNetwork's interactive eLearning tools (IETs) are reusable chunks of training that can be deployed in a variety of courses or training programs. IETs are designed to enhance, not replace hands-on training. Learners are able to enter a hands-on lab...

In the early 1990s, Stephen Fodor and his team developed a technique to produce miniature arrays of biological molecules. Their work led to the first DNA chip, and became the basis of techniques for large-scale genomic studies. The company Affymetrix was spun off in the early 1990s to focus on DNA...

This resource from Johns Hopkins University has audio and interactive components. Various forms of the Fourier series description for periodic signals are based on alternate ways of writing a cosine signal. This resource goes over Phasors, Phasor Sums, Harmonic Phasor Sums, Gibbs Effect, Windowing,...

This interactive presentation, created by Terry Bartelt and hosted by the Electromechanical Digital Library, provides an explanation of how a metal detector functions. Most people take for granted this common piece of equipment, but the science behind its function is actually quite remarkable....

This brief interactive activity, by the Electromechanical Digital Library and Wisconsin Technical College System faculty, explains clearly the reasons to use switches in place of hubs when using an LAN. The animations and corresponding explanations are helpful as the user clicks through each slide...

This resource, provided by Anti-body Engineers, features an image of a 3D model of an Immunoglobulin (IgG) antibody. Users can click on the image and see an IgG antibody in iCn3D, a three-dimensional visualization platform for molecular structures. The IgG antibody model allows for a detailed...

This web-based learning object, created by Terry Bartelt of the Wisconsin Online Resource Center, teaches impedance matching. "Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity."

This website is provided by Shodor Education Foundation and contains a series of online interactive activities designed for use in middle school mathematics. Topics include: Geometry, Algebra, Probability, Statistics, Modeling, Discrete, and others.

 The website provides interactive plasma physics tutorials on topics including electricity, magnetism, energy, and fusion. The site has links to Virtual Tokamak and Virtual Magnetic Stability Modules as well as Java applets to learn about Plasma and Fusion Containment.
