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

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

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 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 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 observe how a two-roll metering system operates.

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.

In this animated object, learners evaluate oral directions and compose questions to clarify ambiguities. This activity has audio.

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

In this animated activity, learners examine how an electronic converter changes digital signals to analog signals. Sections of a synthesizer are identified, and the operation of a D/A converter is demonstrated.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

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

In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short 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 activity, learners examine the operation of a pneumatic cylinder that continuously cycles by extending and retracting.

In this animated activity, learners observe impression procedures.

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.

In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
