Students read about the world's active volcanoes that make up the "Ring of Fire." In an interactive exercise, they locate these volcanoes on maps.

In this learning activity, you'll examine the different ways in which computers and other equipment are physically connected in local area networks and the advantages and disadvantages of each topology.

In this learning activity you'll review the four main purposes for writing documents: expressive, literary, persuasive, and reality.

Learners watch video clips demonstrating the correct procedure for police officers to follow when metering a room.

In this interactive learning object, students view the ammeter connections for measuring currents in a parallel circuit with three branches on an energy concepts lab board. A brief quiz completes the activity.

In this animated object, learners examine how two- three- and four-wire sourcing and sinking sensors operate. A brief quiz completes the activity.

Students read about the importance of the Apgar score in assessing the newborn after delivery. Each sign of the Apgar score is identified with illustrations to help the student recognize the proper rating.
