Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

Learners examine devices that are used to protect a motor from damage, such as fuses, overload heaters, and thermal protectors. A quiz completes the activity.

Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.

In this learning activity you'll explore how a fuse de-energizes a parallel circuit when too many lamps are connected to a power outlet.

In this learning activity you'll be introduced to the either/or fallacy.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

Learners examine eight different kinds of faulty logic or perception that interfere with critical thinking. They are superstition, ignorance, clustering illusion, false analogies, gambler’s fallacy, irrelevant comparisons, post hoc fallacy, and slippery slope fallacy. In an interactive exercise, learners identify ways to overcome these barriers.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

Explore Intrusion Detection Systems, what they are, how they're configured, and the types of protection the provide.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

Learners examine the psychological and sociological barriers that interfere with clear communication. They select examples of ad hominem fallacy, bandwagon fallacy, emotional appeals, red herrings, irrelevant appeals to authority, suggestibility and conformity, “poisoning the well’, and “shoehorning.” In an interactive exercise, learners identify ways to overcome these barriers.

In this simulation activity, an electrician will troubleshoot an AC motor that quit running and cannot be restarted. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

The Animal Welfare Act, or AWA, gives protection to animals used in research, education, and entertainment. Explore ethical use and some of the current alternatives in this module.

In this screencast, the student will learn that regardless of the surface onto which a blood droplet is falling, the angle or velocity at which it does so, or the volume of the droplet, there are four distinct phases involved in the reaction of a moving droplet with impact against a surface.

In this learning activity you'll be introduced to the Ad Absurdum fallacy.

In this learning activity you'll be introduced to the Post hoc, Ergo Propter hoc fallacy.

Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.

In this learning activity you'll be introduced to the eight most common logical fallacies commonly used in persuasive speeches.

In this learning activity you'll be introduced to the Ad Hominem fallacy.
