In this interactive object, the learner practices identifying charges on ions.

Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).

You will encounter real-world challenges that mimic what IT professionals face in day-to-day operations, providing hands-on experience with resolving TPM errors.

In this screencast, learners read an explanation of the file rules and indexing that have been developed by the Association of Records Managers and Administrators.

In this learning activity you'll be introduced to the communication model and how it impacts your work as an IT professional.

Learners read descriptions of the following training and certification levels for organizations using a lean approach to quality: "green belt," "black belt," "master black belt," and "champion."

In this interactive object, students complete progressively more difficult exercises as a way to improve their ability to recognize resistor color code values.

The learner will be able to represent steady-state AC sinusoidal signals using phasors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.

In this interactive object, learners view a practical application of a PLC Timer-On function.

Learners read a description of the parts of an ironworker and identify them in an exercise.

In this interactive object, students view an animated depiction of Class 1 levers. A matching quiz completes the activity.

In this learning activity you'll practice calculating a quadratic variation problem.

Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.

In this learning activity you'll recognize potential safety hazards around grinding equipment

The learner will learn the programming steps that are used to create circular motions with robots.

Learners test their knowledge of how sleep deprivation affects work productivity.

Learners read about the S.O.A.P. and D.A.R. formats that are used to document progress notes in medical records. They then match statements to S.O.A.P. and D.A.R. categories in drag-and-drop exercises.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

In this animated activity, students view a step-by-step approach of how to connect an ammeter to a circuit. A brief quiz concludes the lesson.
