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.

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).

Students review the conditions for giving statements of praise in a way that will motivate employees. They then practice writing these kinds of statements.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

This activity will review determining geometric tolerances for a part.

In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

In this interactive object, learners review the four types of hypersensitivity and check their knowledge of alternative names, mediators, and various antigens and disease conditions.

In this learning activity you'll identify acceptable paraphrases of source material.

Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.

This document gives the procedures for layout on the surface of material.

Learners practice a technique for finding the least common multiple of a group of numbers.

In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.

In this learning object, learners will follow the illness of an 83-year-old woman, noting changes in her condition and ordering the appropriate medical imaging studies needed to inform her physicians about both her progress and her treatment options.

Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.

This learning object describes the equipment and supplies needed to document bloodstain patterns.

In this simulation activity, the lubrication fluid in a milling machine is tested, the condition of its 24 drill bits are inspected and identified before replacing those that are defective.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.

In this learning activity you'll analyze a scenario using operant conditioning. (For security reasons, the ability to email results to your instructor at the end of the lesson has been disabled)

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
