In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.

Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.

This learning activity describes the physical properties that affect the inductance, in henries, of an inductor.

The learner will identify ways to overcome barriers to critical thinking and problem-solving including false memories, personal biases and prejudices, and physical and emotional hindrances.

In this screencast, learners examine the physical facets that determine the value of a capacitor.

Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

In this learning activity you'll explore the physical construction and operation of single-mode and multi-mode fiber-optic cables used in networking.

In this learning activity, you'll examine the different ways in which computers and other equipment are physically connected in local area networks and the advantages and disadvantages of each topology.
