Discuss the relationship between frequency and wavelengths in a transverse wave and compressional (longitudinal) waves.
Use the relationship between wavelength, frequency and wave velocity to find one variable when two are given.
Illustrate the Doppler effect.
Analyze the role of noise as one type of pollution
Distinguish between noise and music.
Research the original scientists of math and sound.
Teach math concepts.
This unit is designed to be taught over one marking period to 6th grade math and science students. The unit is divided into three sections. The first section covers wave characteristics, sound velocity, pitch and frequency and the Doppler effect. The second section explores amplitude, sound pressure level, noise, and musical sounds. The last section focuses on persons involved in the origins of sound.
In order to make this unit meaningful to a math or science class, we must show a relationship between music, math and science. The Pythagorean Doctrine made the connection in this way. Geometry (math) as magnitude at rest. Astronomy (science) as magnitude in motion. Arithmetic as numbers absolute and music as numbers applied.
Students will discuss wave characteristics such as how sound waves travel and two types of wave motion. Students will learn to describe the transmission of sound through a medium and be able to recognize the relationship between amplitude, loudness and frequency of pitch.
Math skills will be taught using information compiled in science class.
Students will learn to apply specific formulas to solve problems. Opportunities will be provided for students to use math skills to measure, calculate, graph, and analyze data and complete mini-lab activities.
When is it music and when is it noise? Students will learn to recognize noise as a form of pollution and identify sounds that are considered noise both through frequency content and loudness. Students will be required to complete a report on the effects of noise on hearing and what can be done to protect their hearing.
Students will be required to research the original great scientists (such as Pythagoras and Thales) of sound and math along with their contributions. The research will be used to prepare a report.
