In this interactive object, learners review respiratory system terminology and then match the terms with their definitions.

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

In this learning activity you'll match introductory sociology terms on culture with their definition.

In this interactive object, learners read the definitions of prefixes and suffixes that relate to the digestive system. They then use this knowledge to combine word components to form medical terms.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

The learner listens to the pronunciation of medical terms using a "jukebox" to select the terms.

In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.

This primer introduces the student to the key terms and concepts associated with the silicon diode.

The learner will understand the meaning of terms and acronyms commonly used in a lean production system.

This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

In this module, you'll build upon the concepts Understanding and Writing Pseudocode: The Basics, by learning new techniques and terms to make your pseudocode more complete.

In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
