IB MYP Assessment Framework

All Four Criteria — Fully Elaborated

Every lesson is mapped directly to the criterion it builds. Each criterion is worth 8 marks in the IB MYP eAssessment.

Criterion A MAX 8 MARKS 🧠

📋 Assessment Strands (I–IV)

Outline chemistry concepts, laws, and theories in familiar and unfamiliar situations

Apply chemistry concepts, laws, and theories to solve problems in both familiar and unfamiliar situations

Analyse and evaluate information to make scientifically supported judgements

Discuss and evaluate the assumptions, limitations, and uncertainties of chemical models used

📚 Topics Covered

Atomic Structure

Atomic number, mass number & isotopes
Electron configuration & shells
Bohr model & quantum model
