Close Encounters of the Polymer Kind
A PowerPoint presents features of polymers and two of its categories (thermoplastics and thermosets). Instructors conduct demonstrations to illustrate the Weissenberg Effect and the Barus & Kaye Effects of polymers in the first...
Cornell University
Electric Vocabulary
Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...
