Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.
Sine Wave Fundamentals: Practice Problem #7
By Patrick Hoppe
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
Orthographic Projection #1
By Glenn Sokolowski
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Weight- Volume Relationships: Saturated Density (Metric)
By Steve Whitmoyer
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
By Terry Bartelt
In this animated activity, learners examine the conductivity of a solution and how its properties affect measurements to determine concentration levels. A brief quiz completes the learning object.
AC Current Flow
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.
