density of the medium. Explore the characteristics of combined waves.

Activity: Musical Instruments

Objective

Overview

Materials

● Students will build and play musical instruments that allow them to compare the relative wavelengths and hear the resulting sounds. ● By increasing the energy used to make the sounds (blowing harder) students will compare the sound
