📐 Prototype Math and Measurement Plan

Using the chosen concept, students create a build-ready plan that links dimensions or setup choices to predicted sound behavior. They calculate target frequencies, wavelength relationships, and expected values using scientific notation and metric conversions, then draft a fair test plan with specific tools such as a tone-generator app, phone frequency analyzer, meter stick, stopwatch, and data table. The output is a one-page prototype plan with predicted results and measurement steps.
