1. SUBJECT AREA/ SUGGESTED GRADE LEVEL: Music and Science / 8th grade – Vibrations in Sound Page 1 of 1 • Standards Addressed in this Lesson: • S8P1. Students will examine the scientific view of the nature of matter. • c. Describe the movement of particles in solids, liquids, gases, and plasmas states. • MMSMA.4 - Improvising melodies, variations, and accompaniments • b. Create musical ideas from a variety of available sound sources Major Art Modality Utilized: Music Multiple Intelligences Addressed: Musical, Naturalist Lesson Abstract: Sound is conveyed most quickly through a solid rather than a liquid or a gas due to the molecules being so close together. With this music project, students can use a solid (metal) to hear the quiet vibrations of sound in creating a “silent gong.” Materials Needed: one (1) wire clothes hanger for each student in the class, yards of string, scissors, pencils, pens. Procedures 1. Discuss the vibrations and the transfer of sound through a solid, liquid, and gas. 2. Demonstrate to the class how sound is conveyed most quickly through a solid rather than a gas by means of a wire clothes hanger. 3. Taking a wire coat hanger in hand, take a piece of string and tie an end of the string to a corner of the clothes hanger. 4. With a second piece of string, tie to the opposing end of the clothes hanger. 5. Wrap one string around an index finger. Wrap the second string around the other finger. 6. With both fingers wrapped with string, instruct the students to plug their ears with their wrapped fingers. Another student will then take an object and strike the clothes hanger, causing it to vibrate. The student holding the strings will hear a “gong” in their ears. Assessment: Students will be able to recognize the low vibrations if they can hear an audible “gong” sound in their ears. Resources/ Links: http://www.alsimmons.com/pdf/SoundsCrazyBooklet.pdf
