Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.
The TI-86 Scientific Calculator: Using the Log Function
By Patrick Hoppe
This primer introduces the student to the correct method of using the log function on a TI-86 calculator.
The Transistor Symbol
By Terry Bartelt
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Time Proportioning Application
In this animated activity, students view the plastic pellets in a profile extrusion machine being melted as the temperature of the heating elements is elevated by a time proportioning control system.
Radiation Pyrometer Temperature Sensors
Learners examine how a radiation pyrometer converts the frequency of electromagnetic waves to a temperature reading.
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.
