In this animated and interactive object, learners examine how a variable voltage is obtained from a variable resistor that is wired as a potentiometer across a fixed DC power supply.

In this animated learning object, students read about the backflow of contaminated water and how to prevent it.

Learners examine OSHA's guidelines of what to include in a bloodborne pathogen exposure control plan for persons who work in general industry, health care, emergency medical services, law enforcement, education, recreation industries, or other occupations in which there is a potential for exposure to blood, blood products, bodily fluids, or human tissues.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. They then answer six multiple-choice questions.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. A brief quiz completes the learning object.

In this learning activity you'll recognize potential safety hazards around grinding equipment

In this learning activity you'll evaluate your stress journals by responding to questions to identify potential stressors of their future careers and personal lives.

In this learning activity you'll analyze the impact of various factors in their lives. They are then transformed by a new identity. They analyze the potential impact of this new identity and compare it to their initial lives.

Learners put themselves in the place of people new to a community. They listen to a woman describing potential neighbors and make judgments about what they’ve heard. They then learn more about the same people and decide if their initial judgments were accurate. This activity has audio content.

In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions

In this learning activity learners will be hear about aspergillus found on marijuana and the potential health hazards that can affect a property room manager. Learners will hear about preventative measures.

Learners follow the FMEA process to predict potential failures and to prevent them. This activity uses the example of getting to work to help participants comprehend the concepts and to apply them to their own work processes.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

In this learning activity you'll use critical thinking skills to rewrite appropriate responses to potentially sensitive words and phrases.
