Lesson 9 · Weeks 14-17
Producing and implementing
Learning intention
Build the system, test each part as you go, and record what you changed and why.
Success criteria
My record shows the version that did not work, the measurement that made me change it, and what I did.
Before class
Set a documentation routine from day one — last ten minutes, every lesson. It will not happen otherwise.
Materials
Student kits, project-specific components, tools per each risk assessment.
Common misconceptions & fixes
Students integrate everything then debug. Test subsystems first, or the fault could be anywhere.
Evidence to collect
Progressive record of evidence: photographs, measurements, modifications with reasons.
Support path
Reduce scope rather than help build. A smaller working system beats a larger broken one.
Extension path
Add a second sensor or a logging output, but only once the core system is reliable.
Exit reflection
What is the one thing you would build differently if you started this again on Monday?
