In this learning activity you'll review what a variable is, how to use variables in JavaScript, and how the computer works with variables.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.

In this learning activity you'll define what a variable is, how they're used in the C# programming language, and how the computer works with variables under the hood.

Learners view colorful animations showing the operation of a VR stepper motor.

In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. A brief quiz completes the learning object.

Students analyze the eight single variable Boolean theorems and their expressions.

Understand the pseudocode structure of variable declarations

Understand the pseudocode structure of variable declarations, a vital component of programming computer and industrial applications.

Learners read definitions of discrete, continuous, attribute and variable data and view examples of checklist, location and item check sheets.

The learner will understand and be able to apply the common welding variables of the GMAW process.

Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.

In this learning activity you'll review independent and dependent variables and view a demonstration of the positive and negative correlation.

Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.

In this learning activity you'll discover how C#, attributes provide a way of associating data with an object in two forms - Fields and Properties.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.

In this learning activity you'll discover the const keyword and it’s uses in C++.

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

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

Students read the multivariable theorems and view the graphic depictions of the Boolean expressions.
