AC Current Flow
By Terry Bartelt
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
The Anatomy of the Heart
By Wendy Dusek
In this animated and interactive object, learners identify the valves and chambers of the heart.
In this learning activity you'll examine how routers transfer data between local area networks and the Internet.
Learners observe animations showing how data is converted between serial and parallel flow.
Hydraulic Directional Control Valves
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
