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 activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

In this animated activity, learners examine the fundamental operation of a logic probe that is used to detect logic signals in a digital circuit.

In this animated activity, learners practice listening and counting the apical pulse of adults, children, and infants.

Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.

In this learning activity, you'll watch an animated explanation of the terms class and object as used by computer programmers, and then contrast the differences.

In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.

In this animated activity, learners examine how ground fault circuit interrupters work and why they are an important safety feature.

In this animated, audio and graphic activity illustration, learners will view design criteria for properly storing property and evidence.

Learners will be able to identify areas within the property room including adjoining work areas, work flow, temporary storage, long-term storage, high profile items, bulk or oversize items, biohazards, hazardous materials, cold storage, administrative area, and release areas.

In this animated activity, learners examine the operation of a pneumatic cylinder that continuously cycles by extending and retracting.

In this animated activity, learners examine a systematic method for converting a decimal number (base 10) into a hexadecimal number (base 16).

In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

Learners read how nanotechnology is creating new jobs in emerging industries while making others obsolete. This colorful and animated activity also looks at the types of products being created through the use of technology and how educational institutions have responded.

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

In this animated activity, learners view the pathways and functions of the fasciculus gracilis and the fasciculus cuneatus.

In this animated object, learners examine how a Hall-effect sensor operates. A short quiz completes the activity.

In this animated activity, learners observe impression procedures.

This activity is cognitive. Learners will actively listen to a story activated by the computer. Then learners will take a quiz on their comprehension. Lastly, learners will compare their chosen answers against the answer key to determine how well they really did "actively" listen. (Credit given to Tom E. Wirkus, University Of Wisconsin-LaCrosse for this activity.)

In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.
