The student reviews definitions of lose/loose/loss and completes a practice exercise.

Learners follow an EMT response at a restaurant involving a woman with slurred speech who has weakness on her right side. Students examine response procedures, resources, and medications.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

In this animated object, learners examine how an enclosed chambered metering system operates.

Learners read a description of the function of the coupling switch on an oscilloscope and how its setting affects measurements of DC, AC, and combined voltages. A brief quiz completes the activity.

Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.

In this animated and interactive object, learners identify musculoskeletal fractures.

Learners examine the factors that contribute to the delays in the response time throughout a closed-loop system.

In this animated object, learners examine the operation of a closed-loop system that maintains the speed of a conveyer belt as heavy boxes are placed or removed.

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.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.

In this accounting learning object, students follow the steps involved in the closing process. Temporary accounts contain ending balances for a specified period and must be closed.

In this animated learning object, students view the operation of an oscilloscope that is used to measure AC voltages. A brief quiz completes the activity.

In this lesson on atomic structure, learners examine how the binding energy of electrons affects light production in certain phosphors used in x-rays.

Learners follow step-by-step instructions for using an oscilloscope to measure DC voltages.

Students read a description of audiograms. They review audiograms representing various degrees and types of hearing loss.

Learners read how Total Productive Maintenance can prevent breakdowns, defects, and a variety of other losses.

In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.
