Work and Energy


A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. Learners ponder the given information and answer questions in the hopes of earning Stars and Medals. These Stars (for answering questions) and Medals (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. The following Concept Builders target concepts associated with Work and Energy.


Name That Energy
 
Learning Goal: To analyze a physical situation and to determine what forms of mechanical energy are possessed by the object in that situation.




What's Up (and Down) with KE and PE?
 
Learning Goal: To analyze a physical situation and to determine whether the kinetic energy and the gravitational potential energy increases, decreases, or remains the same.




Energy Ranking Tasks
 
Learning Goal: To analyze a physical situation and to rank the potential energy, the kinetic energy, and the speed at the various marked locations.




Work
 
Learning Goal: To identify whether positive, negative, or zero work is being done, to identify the force that is doing the work, and to describe the energy transformation associated with such work.
