Science C35: Talking Pictures


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

Product Description

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

  • The same note can sound different.
  • The exact sound depends on how the note is made.
  • The sounds we make when we speak also give different-shaped pictures (on an oscilloscope).
  • Some notes sound musically similar even though one may be high and the other low.
  • The musical note C, for example, can be played at seven different positions on a piano, giving seven different pitches of the same note.
  • For those people with a hearing loss or total deafness, speaking can be difficult, especially controlling the volume or pitch of one’s voice.
  • Oscilloscopes or computer programs that show the different characteristics of sounds in pictorial form can be very useful tools for helping such people develop and control the pitch and volume of their speech.
