2.B Develop a model to describe how a force applied to an instrument causes its shape to change, leading it to repeatedly deform above and below its initial position (effect) as it vibrates and use that model to predict what a force will do to another instrument.
What to do
Use Rubric for Modeling Motion of an Object Making Sounds to assess students’ individual models of a different instrument than the class consensus model. If students are struggling to connect all the components and interactions across instruments, facilitate a conversation comparing the class model to a couple of student models and decide as a class if anything needs to be added or changed about the consensus model or the student models. This could be done the day of or after you use the rubric on each model. It could also help the class agree on a set of conventions for modeling force and vibration with respect to sound.
