Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.

The learner will use the ANSI Insert Identification System to identify and select carbide tools.

In this interactive object, the learner views examples of the neutral position of the back and compares that stance to the flat back and swayback positions. A brief quiz completes the activity.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.

In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

Learners will write effective business messages that incorporate a second-person point of view and focus on the benefit to the reader. This approach is often used to create positive messages, neutral messages, and inquiry messages in business settings.

Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
