Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

In this screencast, you'll distinguish the differences between the content message and the relational message.

In this animated object, learners examine the relationship between pressure and temperature in an air conditioning system.

Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.

Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

In this learning activity you'll examine how firewalls block viruses by discussing trusted, semi-trusted, and untrusted networks.

Learners study the process of mathematically converting temperatures between the Fahrenheit and Celsius scales.

In this learning activity, you’ll discover the difference between a parameter and an argument.

You'll be introduced to the Go-Back-N ARQ, learn what it is, and find out how it's used to keep track of data sent between networked computers.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.

Learners study animations to see the connection between temperature and resistance as they examine the operation of an RTD. A table is used to convert resistance readings to the corresponding temperatures. A brief quiz completes the activity.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

In this activity, you'll distinguish between sexual harassment facts and fiction.

In this learning activity you'll test your knowledge of the roles and differences between the two Houses of Congress - the Senate and the House of Representatives.

In this learning activity you'll identify the difference between needs and wants related to building a personal budget.

Learners observe animations showing how data is converted between serial and parallel flow.

In this learning activity you'll examine the difference between two types of interactions with customers, encounters and relationships.

In this screencast, students read about the key differences between management and leadership activities. They will review typical supervisory activities as either management or leadership.
