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

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 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 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, learners examine the operation of a dynamic braking circuit used to quickly stop a motor.

In this animated lesson, students view the operation of an electromechanical relay. A brief quiz concludes the activity.

In this animated object, learners examine the circuit configuration and operation of a differentiator operational amplifier. A brief quiz completes the activity.

In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.

In this animated activity, learners read and listen to a dialogue in Mandarin Chinese in a grocery store setting. The learner can then click on photos of fruits and vegetables to hear their pronunciation in Mandarin.

In this animated activity, learners examine the operation of the SCR, including how it is biased and how it is turned off. A brief quiz completes the object.

Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.

In this animated activity, learners examine the symptoms of four cardiac conditions: coronary artery disease, myocardial infarction, congestive heart failure, and valvular disease.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

In this animated and interactive object, learners follow steps to perform the process identification procedure for the Ziegler-Nichols Continuous Cycling Tuning Method. A short quiz completes the activity.

In this colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.
