In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.
In this animated object, learners examine the parts of a pneumatic power system, including the prime mover, compressor, and receiver tank, and how they function.
Body Sections and Divisions of the Abdominal Pelvic Cavity
In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.
This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
Assessing the Significance of Agents of Socialization
In this learning object you'll explore how agents of socialization shape a person's life and you'll map the significant events, places, and people that have shaped your life.
In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.
Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.
