Science C34: What Do Sounds Look Like


Award-winning video and lesson investigations for young children on the topic of sound vibrations

Category: Tags: ,

Product Description

Video and lesson investigations on the topic of sound vibrations. Key concepts include:

  • Using a special instrument (an oscilloscope) allows sound to be ‘seen’. Different sounds make different patterns on the oscilloscope screen.
  • An oscillloscopse converts sound vibrations into visual patterns on its screen. These patterns appear on the screen as a series of waves.
  • The lower the note, the slower the vibration and the further apart the wave pattern is.
  • Higher notes form wave patterns which are smaller and closer together because the vibrations are faster.
  • Musical instruments parallel this.
  • Instruments that are used to play deep notes tend to be large, to handle the vibrations (eg. Double-bass, tuba, baritone saxophone) whilst high note instruments tend to be smaller (flute, recorder, clarinet).
