In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

In this learning activity you'll outline a conversation using the transactional communication model. The print and Email function has been disabled. You may take a screenshot of the last screen if needed.

In this animated activity, learners follow a step-by-step approach for connecting a digital multimeter to measure resistance. A brief quiz completes the activity.

In this colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.

In this animated object, learners examine the operation of a summing operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.

In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.

In this animated activity, learners examine the various controls that operate an Ammco brake lathe.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.

Learners examine how five or six groups of electrons around a central atom cause the shape of the molecule to be trigonal bipyramidal, seesaw, T-shaped, linear, octahedral, square pyramidal, or square planar. Seven examples and three interactive questions are provided in this animated activity.

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 view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.

In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.

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.

In this animated activity, learners examine procedures in a doctor blade metering system.

In this interactive and animated object, learners follow instructions for finding the lowest common denominator for a group of algebraic fractions. Immediate feedback is provided. This activity has audio content.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.
