Learning objects Seeing with sound

TLF ID L1306

Explore how sound travels as a wave. Examine diagrams and simulations; answer questions about sound properties. Test the effects of changing wave properties: frequency, wavelength and amplitude. Transmit sounds in a range of mediums: air, water, steel or a vacuum. Find out how echolocation works. Measure speed and direction by using echo. This learning object is a combination of five objects in the same series.



Educational details

Key learning objectives
  • Students use a wave model to explain the behaviour of sound.
  • Students explore the basic properties of sound waves.
  • Students test the effects of varying sound wavelength, amplitude, frequency and medium density.
Educational value
  • Introduces sound as waves of energy caused by objects vibrating and causing particles to vibrate.
  • Students explore the basic properties of sound waves.
  • Students are guided by a series of short questions to view diagrams and simulate sound wave variations in a range of mediums.
  • Students recognise that sound travels faster in denser mediums.
