Play guide
- 1An adult stretches two large rubber bands of different thickness or tension around a sturdy empty box.
- 2Pluck each band gently and decide together which sound is higher and which is lower.
- 3Change the tension of one band slightly, then test again to see whether its pitch changes.
Success signals
The child hears a pitch difference and connects a physical change in the band with a changed sound.
If it's tricky
The two bands sound almost the same: tighten one slightly or use bands with more different thicknesses.
