Organise IB Chemistry through Structure and Reactivity, then strengthen data and investigation skills.

  • Move fluently between Structure and Reactivity models to explain chemical evidence
  • Integrate stoichiometry, energetics, equilibrium and kinetics with chemical interpretation
  • Connect mechanisms, synthesis and analytical evidence rather than memorising isolated reactions
  • Align investigation methods, data treatment and chemical evaluation while preserving student authorship

課程重點

Move fluently between Structure and Reactivity models Select the representation that explains the chemical evidence rather than recalling isolated statements.
Connect scales
Move from electronic and molecular structure to measurable properties.
Choose a reactivity model
Use energy, entropy, equilibrium, kinetics or mechanism appropriately.
Compare explanations
Judge which model accounts for the observation and where it is limited.
 Integrate calculations with chemical meaning Organise stoichiometry, energetics, equilibrium and kinetics around equations, assumptions and evidence.
Establish relationships
Set up balanced equations and mathematical models before substitution.
Handle data quality
Track units, precision, uncertainty and significant figures.
Interpret chemically
Explain the implication for composition, feasibility, rate or extent.
 Build mechanisms and synthesis as connected reasoning Use electron movement, conditions and analytical evidence to explain and plan transformations.
Follow electron flow
Relate nucleophile, electrophile, acid-base and redox behaviour.
Plan routes
Work backwards from a target and test the compatibility of steps.
Use analytical evidence
Combine spectra, observations and chemical tests to justify structures.
 Build a coherent chemical investigation Align question, method, data treatment and evaluation while preserving student authorship.
Control chemical variables
Choose range, concentration, temperature, controls and safety.
Process evidence
Select calculations, graphs and uncertainty treatment appropriate to the question.
Evaluate chemically
Separate measurement limitations from reaction and model limitations.
