Summary

What are phenomena associated with sound? Sound is a form of energy that is created when an object vibrates and causes the movement of air molecules (sound waves). In this unit, students explore elements of sound—sound waves, pitch, volume, frequency and transmission—with a variety of hands-on activities.

Engineering Connection

Many engineering fields apply the principles of sound energy. Biomedical engineers develop ultrasound devices that emit and detect sound waves to quickly and safely produce internal images of healthcare patients. Electrical engineers build antennas that can transmit and receive radio waves. Ships use sonar to safely navigate and detect underwater objects, like reefs and fish. Engineers use instruments that "listen" to ultrasound sound waves to detect minute flaws in materials used to make parts—from bridge bolts to aircraft wings.
