Lesson
Set out your lesson
“Sound Fading with Distance means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- A torch or phone light and a blank wall OR a rubber band / ruler for sound
- Paper for notes
Extra for the adult
Worked example. Move the torch closer: the shadow gets bigger. Distance caused the change.
Optional challenge. For Sound Fading with Distance, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Sound Fading with Distance, not mastery.

Check understanding
- State that sound gets quieter as distance from the source increases
