Apgar Scoring in the Newborn (Screencast)
By Kathy Costa Lieberthal
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.
Apgar Scoring Challenge
Learners consider the Apgar scores for several fictitious newborns. They are then given an Apgar score and proceed to create a situation in which a newborn would receive that rating.
Antihypertensive Drugs

In this learning activity you'll investigate the interaction of antimicrobial therapies and host defenses in eliminating an infection.
Angular Measurement Review
By Kelly Curran
In this learning activity you'll test your knowledge of angular measurement in this 10-question quiz.
Angular Measurement
In this learning activity you'll review angles and different types of angular measuring tools associated with manufacturing.
Angles of Impact (Screencast)
By Daniel Feucht
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.
AND Gates (Screencast)
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
Anatomy of the Lungs (Screencast)
By Ann Jadin
Learners examine the anatomical parts of the lungs.
Anatomy of the Hip
Learners examine and identify the parts of the hip joint.
Anatomy of the Ear
By Donna Matusewic
The student identifies the anatomical parts of the ear and learns the purpose and function of these parts. A review follows the lesson.
Anatomical Terminology: Relative Position
By Barbara Liang
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
