How does someone who is deaf enjoy music? Can they hear it? Can they make it? Through exploring the life and music of Evelyn Glennie, students will understand that music is sound produced by vibrations, and will create their own instrument out of found objects to compose a musical score for presentation.
Can we hear the sounds of music? Students will predict how well they think they can detect the dynamics of music by well known composers. Through scientific inquiry, students will create an entry for the science fair which compares predictions with data collected by a Quacker Tracker while their musical selection is played.
This lesson is designed to teach how sound is produced and how its qualities change depending on the medium through which vibrations pass. The students will be able to 1) identify parts of a sound (sine) wave: amplitude, frequency, phase, crest, and valley; 2) explain the difference between a pure tone and a sound with harmonics; and 3) explain how different musical instruments produce different qualities of sound (timbre).
Ever see a glass tuning fork? Are some materials better suited to make tuning forks? Students will learn the history of the tuning fork and the latest technological advances. They will learn how a tuning fork works and why some materials are better suited to make tuning forks.
In this adventure, students will observe the effect of two factors on a motion plot. They will walk at two different speeds, walk in two different directions, and walk to the tempo of two different classical music selections. The students will then deduce how the value of the slope of a line can be "seen" in its graph.
This lesson is a small part of a larger unit on the science of sound. The unit has several sections, including: how sound is made, the elements of sound, how sounds travel, and how we hear sounds. This particular lesson is part of the section in which we distinguish the difference between musical sound and noise. We examine the different ways in which musical instruments make sound - or the different way each one creates vibrations of air.
