Unit D: Waves & Sound

Big Idea: Use models of waves to understand their application in technology for information transfer

Learning Goal #9: Create a model to describe a sound wave’s motion through various materials.

  • Assessment: Earthquake Rescue Plan
  • Guiding Questions:
    • What is a wave?
      • What is a pulse?
      • How does a wave pulse differ from vibrations?
    • What is a mechanical wave?
      • What are examples of mechanical waves?
    • What is an electromechanical wave?
      • What are examples of mechanical waves?
      • How do mechanical waves differ from electromagnetic waves?
    • What is a transverse wave? What is a longitudinal wave?
      • How do they differ?
    • Understand the following wave properties: Amplitude, Wavelength, Frequency, Wave speed, Pitch, Volume
    • How is sound created? How does sound travel?
    • How do sound waves behave through different mediums: Liquid? Gas? Solid?
  • WAVE Resources:
  • SOUND Resources:

Learning Goal #10: Use evidence to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

  • Assessment: Activity: Digital vs Analog
  • Guiding Questions:
    • How do analog signals transmit information?
    • How do digital signals transmit information?
    • Which is more reliable, digital or analog?
  • Resources:
