An understanding of the properties of sound is important in making connections to communication, technology, and health.
Students discover the properties of sound through exploration and experimentation.
They explore how sounds change and travel by experimenting with a variety of objects such as tuning forks, bottles, rubber bands, and cup telephones. As a result of these experiences, students begin to understand how humans hear sounds and how sounds are made. Activities Students listen to and describe a variety of sounds, then try to identify their pitch, quality, and intensity. Students could then use tuning forks to explore the vibrations that make sounds. Students explore how sound changes as it travels through various materials.
