Session by session
- Session 21 · Ask & understandWeek 11
How can a circuit check an answer?
Evidence: a question, sketch or new vocabulary
- Session 22 · Build & designWeek 11
Plan the questions and the hidden foil paths
Evidence: a design draft, dataset or build
- Session 23 · ImplementWeek 12
Build the two-question board
Evidence: a working version, explained once
- Session 24 · Test & improveWeek 12
Test the right and wrong pairs
Evidence: a test log with at least one failure
- Session 25 · Explain & reflectWeek 13
Explain how the hidden path works
Evidence: an individual explanation
- Card board
- foil strips
- insulated wires
- LED module
- enclosed AA battery holder
Each right pair lights and each wrong pair stays dark, checked five times.
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.
