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 the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.
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 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.
Barriers to Critical Thinking: Faulty Logic or Perception
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.
Troubleshooting a Three Phase Motor that is Overheating
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.
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.
Barriers to Critical Thinking: Psychological and Sociological Pitfalls
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.
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 interactive object, learners examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.
