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 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.

In this learning activity you'll explore the food pyramid and the recommended services.

Learners examine how a ladder logic circuit becomes latched when a normally open pushbutton is momentarily pressed.

In this learning activity you'll understand what flow charts are and how they're used to create computer programs.

In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.

In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.

In this animated activity, learners read the definition of a parallelogram and then find the perimeter and area of parallelograms in practice problems.

Learners are asked to control the Adira press brake following the same steps they would if working on the actual machine.

Understand the pseudocode structure of variable declarations

In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.

Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.

In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

Learners examine phase diagrams that show the phases of solid, liquid, and gas as well as the triple point and critical point.

In this simulation, learners follow 10 steps to program a job to saw metal. This activity includes a video clip.

In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.

Learners study the process used to diagram sentences, and then work through numerous exercises to test their knowledge.

Learners view the seven segments of an Ethernet frame and the types of information each represents.
