In this interactive activity adapted from A Science Odyssey, students will look at how technology in the home has changed over time. Specifically, they will examine a timeline from 1900 to 2010 and think about technological innovations and how they changed our daily lives. The material is intended...

Provided by Wisc-Online and the National Science Foundation, this website provides a plethora of information on coaxial cables including what an RG rating is, what a code is, and how each type of cable is used. This interactive slideshow goes into greater detail about an RG-8, 10Base5 cable and an...

We all know how important computers are in our every day communication, but do you know how the computer in your office transfers information between the others? This online slideshow provided by Wisc-Online and the National Science Foundation explains the difference between a switch and a hub and...

This interactive presentation, created by James Bourassa and hosted by the Electromechanical Digital Library, provides a detailed explanation of different physics laws regularly employed by electricians. The presentation performs rearrangements of Ohm's and Watt's laws, these respectively being V=IR...

This website presents an animated "tour" of the basics of DNA and genes. Students will get the chance to learn more about DNA, genes, chromosomes, proteins, traits and heredity. 

In "The Lab: Avoiding Research Misconduct," students will become the lead characters in an interactive movie and make decisions about integrity in research that can have long-term consequences. The simulation addresses Responsible Conduct of Research topics such as avoiding research misconduct,...

This learning object, created by Terry Bartelt of the Wisconsin Online Resource Center, focuses on reflected load in a transformer. This employment of Flash allows users to interact with the presentation. Overall, this is a nice introduction to the basics of this specific topic.

This Web site features a series of animations showing the operation of a vortex flowmeter that is used to measure flow in a process control system. Besides defining a vortex flowmeter, a Flash animation shows how it causes vortices around a blunt object obstructing the flow. A sine wave flow is...

This resource provides an interactive activity on field effect transistors. These are "a type of transistor that utilizes an electric field to control the shape of a channel in which charge carriers in a semiconductor material flow." An interactive diagram is presented allowing students to...

This interactive presentation, created by Terry Bartelt and hosted by the Electromechanical Digital Library, discusses the tri-state buffer used in devices employing digital circuitry. A tri-state buffer is "one type of device that is used in digital circuits receiving two logic states but producing...
