Chemistry CGSE
Specification: Edexcel

From Year 9 onwards, the material is GCSE standard and all lessons are taught by specialist teachers. Lessons contain practicals when possible, so experimental and analytical skills can be developed, as well as the mathematical techniques essential for success in the subject.

Year 9
Pupils receive two hours a fortnight for each of the three sciences. In Chemistry, there are 4 overarching areas: States of Matter, Atomic Structure, The Periodic Table and Bonding. The topics are short and will be continued in further years as part of a ‘spiralling curriculum’.

Topic 1 (Sep-Oct)
States of Matter
Topic 2 (Oct-Nov)
Atomic Structure
  • States of matter
  • Mixtures
  • Filtration and crystallisation
  • Paper chromatography
  • Distillation
  • Drinking water
  • Structure of an atom
  • Atomic number and mass number
  • Isotopes
Topic 3 (Dec-Jan)
The Periodic Table
Topic 4 (Jan-Mar)
  • Elements and the periodic table
  • Atomic number and the periodic table
  • Electronic configurations and the periodic table
  • Ionic bonds
  • Ionic lattices
  • Properties of ionic compounds
  • Covalent bonds
  • Molecular compounds
  • Allotropes of carbon
  • Properties of metals
  • Bonding models

Year 10
Pupils receive three hours a fortnight. In Chemistry we start with going over the bonding topic from Year 9. There are four further overarching areas: acids and alkalis, calculation involving masses, metals and electrochemistry and quantitative analysis.

Topic 4 (Feb-Apr)
Metals and electrochemistry
Topic 5 (Apr-Jul)
Quantitative analysis
  • Electrolysis
  • Reactivity
  • Ores

  • Concentrations
  • Titrations
  • Molar volumes of gases
  • Haber process
  • Factors affecting equilibrium
  • Chemical and fuel cells

Year 11
Pupils receive four hours a fortnight. In Chemistry, there are 4 overarching areas: Chemical Reactions, Chemistry and the Environment, Organic Chemistry, and Qualitative Analysis.

Topic 1 (Sep-Oct)
Chemical Reactions
Topic 2 (Nov-Dec)
Chemistry and the Environment
  • Group in the Periodic Table
  • Halogen reactivity
  • Rates of reaction
  • Factors affecting reaction rates
  • Catalysts and activation energy
  • Energy changes in reactions
  • Hydrocarbons and crude oil
  • Combustion
  • Fuels and pollution
  • The early atmosphere
  • The atmosphere today
  • Climate change
Topic 3 (Jan-Feb)

Topic 4 (Mar-Apr)
Qualitative Analysis
  • Alkanes and alkenes
  • Alcohols and ethanol production
  • Carboxylic acids
  • Polymers
  • Addition polymerisation
  • Condensation Polymerisation
  • Flame tests
  • Tests for anions
