Physical Science: Sound

Vendor:  STC

Students use tuning forks, slide whistles, strings, and other sound-producing objects to investigate the characteristics of sound.  Students learn that sound is caused by vibrations, and they explore how sound travels.  They learn about the relationship of pitch and volume to the frequency and amplitude of vibrations.  They also learn about the anatomy and functioning of the human ear.  They apply what they learn in the unit by designing and building musical instruments or other sound-producing devices.
