Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.

In this learning activity you'll practice converting between degree minute second and decimal degree.

Students read an explanation of the operation of an operational amplifier that functions as a comparator.

Learners study animated rheostat settings that show how current flow is inversely proportional to resistance. Ten review questions complete the learning object.

In this animated and interactive object, learners examine ABO blood antigens and Rh antigens and their compatibility.

Learners distinguish between competencies that are effective and robust, and those that are ineffective and weak. The learning object is designed for faculty who are writing or revising courses. It contains audio.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

Learners answer questions about internal combustion engines using a game board format. This learning object can be used individually, in small groups, or as a class activity to provide an alternative self-assessment tool.
