Session by session
- Session 01 · Ask & understandWeek 1
Sound as vibration: amplitude, noise and thresholds
Evidence: a question, sketch or new vocabulary
- Session 02 · Build & designWeek 1
Wire the sound module and read its output
Evidence: a design draft, dataset or build
- Session 03 · ImplementWeek 2
Log readings and estimate the noise floor
Evidence: a working version, explained once
- Session 04 · Test & improveWeek 2
Test distance, surface and background noise
Evidence: a test log with at least one failure
- Session 05 · Explain & reflectWeek 3
Justify a trigger threshold with numbers
Evidence: an individual explanation
- Grade 12 UNO
- sound sensor module (LM393)
- USB
- breadboard
- jumper wires
Twenty readings each in quiet and noisy conditions; the threshold is set from data, not guesswork.
A physical circuit, sensor or mechanism, built and tested on the bench.
Completion needs the artefact, an honest test log, an individual explanation and no open safety or privacy issue.

For school leadersChoose a starting point.
Build from evidence.
Pick the classes and a plan. We map the timetable, kit and safety checks with you, then pilot one class first.
- Prospectus and class-wise plan
- Kit and readiness check
- Pilot one class first
- Evidence at every milestone
Let's plan your pilot.
Share a few details and we will send the right plan for your classes.
