Our essential questions for this unit are: How am I able to differentiate between musical songs? Why doesn’t all music sound the same?
When students finish this unit, they should have an enduring understanding of the following topics:
- sound is a form of energy;
- sounds are created by vibrations;
- sound is transmitted through a medium (solid, liquid, gas);
- sound cannot travel through a vacuum (space);
- sound spreads outward from its source, traveling in waves in all directions; and
- pitch is determined by vibration frequency and the size of the object that is vibrating.
Topic 1- Characteristics of Sound
- Recognize vibrations cause sound
- Recognize sounds travel at different speeds through different media (solids, liquids, gases);
- Manipulate a variety of objects to produce vibrations and create sounds
Topic 2- Sound Changes
- Recognize that fast vibrations create a high pitch; and slow vibrations create a low pitch.
- Identify conditions which cause changes in pitch, volume, and loudness.
- Demonstrate how to change the pitch of a vibrating object.
