POE Lesson 4.17 | LockwoodSTEM

✓Lesson Snapshot

I can collect repeated performance data and use early results to improve a rover or motion system.

Run official trials, record data, identify variation, and make one justified improvement if time allows.

Official test data and iteration notes

Notebook, data sheet, test system, measurement tools, timer/video option

1ProblemUnderstand the challenge and why it matters.

Testing is only useful when data are complete, units are consistent, and changes are documented. Iteration should be based on evidence, not guessing.

2ConceptLearn the engineering idea or skill.

Repeated trials reveal performance and consistency. Engineers use early results to identify errors, adjust designs, and improve reliability.

3ApplyUse the skill in a guided task.

Run official trials, calculate initial results, and decide whether a revision is needed based on the evidence.

4DocumentRecord your evidence and decisions.

Record raw data, units, observations, failed trials if any, revision notes, and the reason for each change.

5ReviewCheck quality and identify your next step.

Your data should be complete enough to support a final claim.

Use these files and shared website resources when they support today’s work.

Use for graphs, calculations, motion diagrams, data displays, and design sketches.

Use for repeated trials, rover-distance data, timing data, accuracy measurements, and observations.

Templates, reference sheets, sketch paper, and course support files.
