How It Is Used
The pipes stand on a stable surface and students blow across or into each one in turn, listening to the note it makes. Arranging them from shortest to longest makes the gradual change in pitch easy to hear and leads into a discussion of vibrating air columns.
Frequently Asked Questions
How does the Sound Pipes Model show the effect of length?
Each pipe has a different length and gives a different pitch. Placed in order from shortest to longest, they let students hear the pitch change step by step.
