Sound and Music introduces students to the characteristics of waves through ten simple interactive activities. Students visualize how sound waves travel using a slinky. They observe vibrations produced by tuning forks and learn how differences in fork length correlate with vibration frequencies humans perceive as differences in pitch. Students model their own musical instruments and explore the musical scale, stringed instruments, and wind instruments. The structure and function of the human ear are introduced. Allow 2 hours for investigation. Designed for 24 students working in groups.
