In this interactive object, learners check their knowledge of concepts related to the cost of ensuring quality in manufacturing as they relate to the categories of appraisal, prevention, internal failures, and external failures.
Learners answer questions about medication from a game board with the headings "Pituitary," "Thyroid," and "Adrenal." Up to three people can play at one time. Contestants "buzz in" their answers to accumulate points.
In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.
The Mathematical Expression of an AC Sine Wave As a Function of Time: Practice Problems
Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.
The Multiplexer/Demultiplexer IC Data Transfer Circuit
In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.
Students view the steps, symbols, and benefits of creating a process flowchart. They then perform a self-assessment to determine their level of understanding.
Learners listen to effective techniques to successfully interact with customers via the telephone. They also submit their own suggested replies to customers in various scenarios. Topics include general telephone etiquette, dealing with angry callers, working with confused or unsure customers, and managing voicemail. A quiz completes this customer service activity.
