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. The following Concept Builders target concepts in Wave Motion and Sound.



Wave Basics
 
Learning Goal: To understand basic concepts associated with the nature, the categories, and the anatomy of waves.




Matching Pairs: Wave Characteristics
 
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.





Wavelength
 
Learning Goal: To understand the concept and mathematics of wave properties such as wavelength, amplitude, frequency, period, and speed.





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.




Wave Interference
 
Learning Goal: To understand the principle of superposition and to use it to construct the shape of a resultant wave formed by the interference of two waves.




Decibel Scale
 
Learning Goal: To determine the deciBel rating of a sound if it is known to be so many powers of ten more (or less) intense than another sound with a known deciBel rating.




Name That Harmonic: Strings
 
Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.




Name That Harmonic: Open-End Air Columns
 
Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.




Name That Harmonic: Closed-End Air Columns
 
Learning Goal: To use the relationship between frequencies between the various harmonics and to use the length-wavelength relationship to identify the standing wave pattern for a harmonic.
