# Mission: Complete the "Feel the Force: Magnetism" Criterion C lab report

## Why

The learner must understand — and be able to do — the work stated in the assessment doc
(Google Doc `1s03PpXGwHIEHLq1laQC9av7zdQ68Dy5zPTsgOF8Sfiw`, local copy in
`_RESEARCH_ARTIFACTS/doc-export.txt`): a magnetism investigation measuring the force between
two neodymium magnets with a top-pan balance, then an individual Criterion C report with five
sections (Data Presentation → Suggestions for Improvements and Extensions), marked out of 8
across strands i–v. Teaching language: Vietnamese. The final report itself is written in
English (template headings, formal scientific style), so worked examples mirror the report's
English conventions.

## Success looks like

- Can explain why the balance reading changes when the magnets repel or attract, and in which direction
- Can convert a balance-reading change (g) into a force (N) using F = mg with g = 9.8 N/kg
- Can identify the independent, dependent and controlled variables of this investigation
- Can process raw readings (mean of three per distance) into a numbered, titled table
- Can plot force vs distance with correct axes, units and line of best fit, and describe the trend
- Can evaluate the hypothesis and the method against the actual data, citing evidence
- Can propose realistic improvements and extensions tied to named weaknesses

## Constraints

- Learner-agnostic (Thinh's instruction, 2026-10-12): zero assumed prior knowledge — every
  lesson starts from fundamentals
- Bilingual lessons (Thinh's instruction, 2026-10-12): every lesson and reference doc ships
  as a Vietnamese (Northern register) + English twin, cross-linked; the report-writing
  conventions stay in the assessment's English format
- The report must be the learner's own work; AI use must be declared in the template's
  declaration — the lessons teach skills, they never draft report content
- The learner's actual group raw data is not yet available; lessons use clearly-labelled
  practice datasets until it arrives

## Out of scope

- Writing any part of the actual report for the learner (academic integrity; the doc's
  declaration requires self-completion)
- Electromagnetism, induced currents, formula-level field theory (F = qvB, right-hand rules) —
  beyond what this investigation needs
