Sound (Y4)

Prior learning

  • Identify, name, draw and label the basic parts of the human body and say which part of the body is associated with each sense. (Y1 - Animals, including humans)

Future learning

  • Waves on water as undulations which travel through water with transverse motion; these waves can be reflected, and add or cancel – superposition. (KS3)

  • Frequencies of sound waves, measured in Hertz (Hz); echoes, reflection and absorption of sound. (KS3)

  • Sound needs a medium to travel, the speed of sound in air, in water, in solids. (KS3)

  • Sound produced by vibrations of objects, in loud speakers, detected by their effects on microphone diaphragm and the ear drum; sound waves are longitudinal. (KS3)

  • Auditory range of humans and animals. (KS3)

  • Pressure waves transferring energy; use for cleaning and physiotherapy by ultra-sound. (KS3)

  • Waves transferring information for conversion to electrical signals by microphone. (KS3)
