Overall goal of the module (reference: The standards that reflect intended Enduring Understanding)The student will:A.)  model a longitudinal (compression) wave and diagram, label, and describe the components (wavelength, compression, and frequency) (PS.6 a)B.)  explain the relationship between frequency and wavelength (PS.6 a)C.)  plan and conduct an investigation related to sound (the investigation may be a complete experimental design or may focus on systematic observation, description, measurement, and/or data collection and analysis) (PS.6 b)This module was developed by Tracey Nipper as part of a Virginia Commonwealth University STEM initiative sponsored by the Viginia Department of Education.

Students learn about the types of waves and how they change direction, as well as basic wave properties such as wavelength, frequency, amplitude and speed. During the presentation of lecture information on wave characteristics and properties, students take notes using a handout. Then they label wave parts on a worksheet diagram and draw their own waves with specified properties (crest, trough and wavelength). They also make observations about the waves they drew to determine which has the highest and the lowest frequency. With this knowledge, students better understand waves and are a step closer to understanding how humans see color.
