In this interactive exercise, learners label the components of a workstation, a Windows desktop, and an application window.

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

Learners examine the method used to calculate the mass percent of an element in a compound. Three examples and one problem illustrate the method.

Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.

In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.

In this learning activity you'll explore three common network protocols that computers use to communicate in a network.

Students review the rule for pluralizing compound nouns. They then complete an exercise.

In this learning activity you'll review the rules for using commas to divide nouns written in a series and complete an activity.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

Learners study animation showing the operation of cumulative and differential DC compound motors. A short quiz completes the activity.

Learners examine the theory of operation for a combustible gas detector. A brief quiz completes the activity.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

Learners compare animations of analog and digital data signals. A short quiz completes the activity.

Learners examine the complex number function to convert real and imaginary coefficients into a complex number.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

Learners follow steps to size an interior grease interceptor for a commercial dishwasher. This animated learning object presents plumbing code requirements and industry standards. A brief quiz completes the activity.

Learners read about nonverbal communication. In a drag-and-drop exercise, they evaluate photos of people interacting and determine if the behaviors shown interfere with communication or enhance it.

Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.
