Waves and Sound


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 Trophies. These Stars (for answering questions) and Trophies (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. The following Concept Builders target concepts in Wave Motion and Sound.



Wavelength
 
Learning Goal: To use an understanding of wavelength in order to identify a wavelength and to calculate it if given a wave pattern and its length.




Waves - Case Studies
 
Learning Goal: To predict the effect of wave properties and medium properties upon the speed and wavelength of a wave.




Rocking the Boat
 
Learning Goal: To use an understanding of wave properties - wavelength, frequency, period, amplitude, and speed - to analyze a physical situation.
