Lesson Planning
Teaching
- Explore how you can vary the volume of a sound.
- Explain changes of volume/loudness in terms of energy and strength of vibration.
Activities
- Explore how to play a repeated rhythm and change the volume up and down (Yrs3&4).
- Explain the changes of volume in terms of energy (Yr3) and strength of vibration (Yr4).
- Record decibels using a sound probe and seek to answer a question with a simple exploration (Yrs3&4).
Investigation - exploring, pattern seeking
The band want to include some instruments that can play notes of different pitch. Can you investigate different sized pipes, sticks, tubs and rubber bands to find out what happens to the pitch of the note?
Year 3 - Place a given set of “instruments” in order of pitch and explain what you notice.
Year 4 - Explain the link between pitch and size/length of a vibrating object.
