Learners read about nonverbal communication. In a drag-and-drop exercise, they evaluate photos of people interacting and determine if the behaviors shown interfere with communication or enhance it.
Learners examine how five or six groups of electrons around a central atom cause the shape of the molecule to be trigonal bipyramidal, seesaw, T-shaped, linear, octahedral, square pyramidal, or square planar. Seven examples and three interactive questions are provided in this animated activity.
Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.
In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.
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.
In this animated activity, learners listen to instructions for simplifying a complex fraction by finding the least common denominator. This learning object requires a computer that is equipped with speakers.
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.
In this animated activity, learners read and listen to a dialogue in Mandarin Chinese in a grocery store setting. The learner can then click on photos of fruits and vegetables to hear their pronunciation in Mandarin.
In this animated object, learners examine the operation of an optocoupler, specifically how it is connected to external components to provide interfacing and isolation and how it responds to excessive frequencies. A quiz completes the activity.
