KHAEMENES ACADEMY · CHEMISTRY 11 · WEEK 18 · DAY 03

Lab & Evidence Portfolio Audit

Audit semester evidence for traceability, raw data, calculations, uncertainty, and revision history.

Assessment boundary

This week contains public formative review, evidence audit, and correction support only. Protected midterm questions, answer keys, grading logic, and authentication details remain outside the learner-facing repository.

Explicit chemistry instruction

Strong laboratory evidence preserves raw observations before graphs or derived quantities.

Each conclusion should be traceable through transformations, units, assumptions, and uncertainty.

Missing evidence should be repaired only from authentic records; never invent data to make a portfolio appear complete.

Vocabulary: portfolio audit; raw data; data lineage; uncertainty; revision.

Worked example

A graph with no raw table cannot be independently reproduced. A final calculation with no units or assumptions cannot be fully audited.

Guided question

Choose one lab from the semester and trace every step from raw evidence to conclusion.

Independent work

  1. Audit at least three lab/investigation records.
  2. Flag missing raw data, units, uncertainty, or reasoning.
  3. Create one repair plan based only on authentic records.

Misconception check

Portfolio cleanup must not rewrite history or fabricate observations.

Formative check

What makes evidence traceable?

Reveal response

Raw data, documented transformations, units, assumptions, and revision history.

Mentor evidence conference

Archaemenes may challenge reasoning and help plan corrections but cannot reveal protected answers or grant official mastery.

Teacher guidance

Foundation: Use an evidence checklist.

Core: Complete a three-record audit.

Extended: Trace uncertainty through one multistep calculation.
