I found it very interesting to read this STEM lesson. I have a question, what does the structure of the Harmonica have to do with students' products? Can you explain more clearly about the physics knowledge used here? Thank you so much

Re: Question about Make Your Own Harmonica! activity
Hi - This activity has two explanatory sections at the bottom. The Digging Deeper section helps explain how the design of even this simple harmonica creates vibrations at different frequencies.
