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.

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

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

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 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.

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

Learners solve two sample problems for a numerical reasoning assessment.

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

Learners solve two sample problems for an abstract reasoning assessment.

Learners solve two sample problems for a mechanical reasoning assessment.

Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.

Students read an explanation of the summing amplifier and the formulas for closed-loop gain. An example is given.

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.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.

Students read an explanation of the common-source and source-follower amplifiers. Gain formulas are developed and an example is given.

In this learning activity, learners review the value of health and wellness as it relates to exercise, nutrition, intimacy, and spirituality. Examples of each are identified, and learners are given the opportunity to reflect on how these examples are associated with health concerns in older adults.

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).

In this animated and interactive object, learners examine a heat exchanger as an example of an automated closed-loop system.
