Regents Physics Chapter 13 & 14 Reading Questions, Test Date and Project
Project – build a musical instrument - 4/22
Each instrument should be homemade and should meet the following requirements:
1. Each group (one to maximum 4 people) must make one musical instrument.
2. The instrument is to be made from common household materials.
3. The instrument must be capable of producing a complete octave.
4. Each instrument must be accompanied by a description that explains the workings of the
instrument and describes in detail how physics principles apply to the instrument. Please
read chapter 13 for explanation of simple musical principles.
