BIG IDEAS

  • Waves transfer energy without transferring matter.

  • I can explain why my friend's voice sounds different when I'm under water.
  • I can explain how sound is a part of every aspect of my life.

UNDERSTANDING THE STANDARD

  • Resonance is the tendency of a system to vibrate at maximum amplitude at certain frequencies. 
  • Reflection and interference patterns are used in ultrasonic technology, including sonar and medical diagnosis.
  • Reflection and interference patterns are used in ultrasonic technology, including sonar and medical diagnosis.

ESSENTIALS

  • Identify examples illustrating resonance (e.g., musical instruments, Tacoma Narrows Bridge, crystal stemware).
  • Describe technological applications of sound waves and generally how each application functions.
  • Design an investigation from a testable question related to sound. The investigation may be a complete experimental design or may focus on systematic observation, description, measurement, and/or data collection and analysis.
