In this animated and interactive object, learners use a color code to understand the operations of a hydraulic circuit. A brief quiz completes the activity.

Students read how profits can be doubled with the elimination of only a fraction of the "waste" in a company's operation.

Learners read a passage and answer two questions based on the information found it that passage. Immediate feedback is provided.

Learners read a description of inductors and view examples of inductors in series and in parallel.

In this interactive object, learners follow the steps required for the Ziegler-Nichols Continuous Cycling method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

In this animated object, students examine the role that the solubility of water plays in various biological functions.

Learners mentally manipulate two-dimensional diagrams to visualize the objects in their three-dimensional forms.

Learners solve two sample problems for an abstract reasoning assessment.

Learners solve two sample problems for a numerical reasoning assessment.

Learners solve two sample problems for a mechanical reasoning assessment.

Learners choose the meaning of a selected word in a sentence.

Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.

In this learning activity you'll review the hazardous materials safety document which display an example of a SDS or MSDS (Material Safety Data Sheet).

Users view effective and ineffective methods of assessing a task. Flight training is used as an example of an area that needs authentic assessment.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.

In this learning activity you'll review definitions then match the transactional communication model element with the definition or example.

In this animated object, learners follow the steps for solving word problems using algebra. An introductory example is explained.
