In this animated object, learners examine the hysteresis function of a sensor.

In this animated object, learners follow the steps for solving word problems using algebra. An introductory example is explained.

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 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.

In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.

In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.

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 operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this animated object, learners examine the types of information to enter, and the sequence of steps required, to program a programmable logic controller (PLC) timer.

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.

In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.

In this animated object, learners examine the operation of a pneumatic directional control valve using air pilot lines.

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 interactive object, students view an animated depiction of Class 3 levers. A matching quiz completes the activity.

In this animated learning object, users view the process of entering a formula in an Excel spreadsheet. Several different methods and associated examples are given.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

In this animated object, learners examine the operation of a Schmitt Trigger IC and its hysteresis function. A brief quiz completes the activity.
