The learner tests his/her ability to set up the optical comparator edge detector using a virtual simulation of the machine.

Students read how to set up the optical comparator edge detector in this interactive learning object.

Learners read descriptions of three work teams and decide how to assign four recently hired employees who are new to the United States.

This project gives a drawing with steps to complete the activity.

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees

This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.

You'll practice converting between units of measure for time.

You'll practice converting between units of measure for volume in the English Measurement System.

You'll practice converting between units of measure for weight in the metric and English measurement systems.
