In this learning activity you'll identify points on a coordinate system.

Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.

Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

Students identify the meaning of urinary system word parts to analyze and define medical terms.

In this screencast, learners identify the parts of the cardiovascular system and examine blood flow.

In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

In this learning activity you'll examine how computers operate in a peer-to-peer network operating system.

Students read about the Federal Reserve System's structure and goals and the tools it uses to control the flow of money and credit in the economy. At the end of this activity, learners are asked to write how they would solve specific economic problems if they served on the Fed's Board of Governors.

Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.

Learners study two diagrams of the lymphatic system and then test their knowledge in drag-and-drop exercises.

In this learning object, students will learn about the attachment

process of specific sugars to red cell membranes and how the sugars

determine ABO antigenic activity.

In this animated object, learners examine how to align a part on the 1808 CMM.
