Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

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.

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.

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

In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position. Check out our video on relative position: https://bit.ly/2kTXujp

Learners will understand the technical terms used in the context of the SDS to help them interpret its information.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

In this learning activity, you'll watch an animated explanation of the terms class and object as used by computer programmers, and then contrast the differences.

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.
