Prep: 10 minActivity: 30 min1 session~$2/groupOne table for the Sound Wave Visualizer & Original Composition evidence and prototypeBeginner-friendly

Setup

Print or handwrite the four Sound Wave Visualizer & Original Composition challenge steps and place common paper supplies on one table. Prepare one small sample, dataset, scenario, or recycled-material model drawn directly from the project description; no device, paid tool, room decoration, or purchased kit is required.

Activity

  1. Read the Sound Wave Visualizer & Original Composition challenge aloud, then record three short clips: a low note, a high note, and a percussive hit.
  2. Use paper, index cards, recycled objects, or facilitator-provided sample data to load each clip into a free waveform viewer and compare frequency and amplitude.
  3. Run one tabletop trial and sketch how pitch relates to wave frequency in your notes.
  4. Finish by compose a 30-second piece that intentionally varies pitch and volume, then present the waveform alongside it; record the evidence that supports the decision.

Done when: The group completes a defensible Sound Wave Visualizer & Original Composition solution, records at least one test result or comparison, changes one claim or design in response, and supports its final decision with that evidence.
