Lesson details

Key learning points

  1. Pitch and volume are different things.
  2. Pitch describes how high or low a sound is.
  3. Amusia, or tone deafness, is the inability to detect pitch, and only affects around 4% of the population.
  4. Sound is made when an object vibrates. Different objects produce different pitch sounds when they vibrate.
  5. Some objects vibrate to produce more than one pitched sound.

Keywords

  • Sound - We hear sound with our ears.

  • Pitch - Pitch is a measure of how high or how low a sound is.

  • Detect - To detect something is to find it or discover that it is present.

  • Vibrations - Vibrations are when an object moves very fast from side to side.

Common misconception

Children may think that the volume of sound and the pitch of sound is the same thing, or that high sounds are loud and low sounds are quiet.

It is important to expose children to a wide range of high and low pitched sounds. Continue to make the distinction between volume and pitch throughout the lesson.

Use a shatterproof plastic ruler for the final P task, but make sure it has some flexibility. You could video the ruler in slow motion to observe the vibrations.
Teacher tip

Equipment

Reusable plastic bottle and glass bottle (of similar sizes), 30 cm ruler made of quite flexible plastic.
