Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Dietary Manager Training: Cooling Foods by Reducing the Quantity or Size of the Food
In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.
Learners listen to an office conversation. They then review tips on how to improve the feedback they give others and practice writing a response based on the conversation they heard.
In this learning activity you'll explore the four stages of conflict (latent, triggering incident, conflict, new equilibrium) and then creates a similar diagram applying to a specific personal conflict.
In this interactive exercise, learners review definitions of 26 terms and then test their knowledge in a matching exercise. Only six terms are included in the quiz; however, if the learner clicks “Restart,” more terms appear in random order.
This learning object has been created to educate workers about the occupational risks of being exposed to bloodborne pathogens as described in the U.S. Occupational Safety and Health Administration (OSHA) 29 CFR 1910.1030- Bloodborne Pathogen Standard.
The student reads definitions of four basic assimilation patterns in American society and creates a model for each by clicking and dragging building blocks. The student also writes a brief explanation of each new model.
Learning About Multiple Intelligences in the Land of Oz (Screencast)
In this screencast, students read about the seven types of intelligence identified by psychologist Dr. Howard Gardner. They then review the type(s) of intelligence of each character in the Land of Oz.
