This resource is an interactive student tutorial on the topic of sound, designed for secondary science learners.  It is organized into sequenced headings that contain interactive animations and guided review questions.  It begins with an overview of vibration and properties of sound, then expands into the human ear, pitch/frequency, the Doppler Effect, constructive and destructive interference, and ultrasound.

This resource is part of a collection developed by the Non-Destructive Testing Resource Center at Iowa State University.

Please note that this resource requires Flash.

4. The Physical Setting

4F. Motion
  • 6-8: 4F/M2. Something can be "seen" when light waves emitted or reflected by it enter the eye—just as something can be "heard" when sound waves from it enter the ear.
  • 6-8: 4F/M4. Vibrations in materials set up wavelike disturbances that spread away from the source. Sound and earthquake waves are examples. These and other waves move at different speeds in different materials.

AAAS Benchmark Alignments (1993 Version)


F. Motion
  • 4F (9-12) #6.  Waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material. All these effects vary with wavelength. The energy of waves (like any form of energy) can be changed into other forms of energy.
