Course Syllabus
Term 1 follows the Year 9 Chemistry scheme of work across 36 self-study sessions. C9.1 develops the particle model, states of matter, mixtures, separation techniques, chromatography and distillation. C9.2 covers the history of atomic models, subatomic particles, atomic number, mass number, electronic configuration, isotopes and relative atomic mass. C9.4 studies Mendeleev, periodic-table development, groups, periods, metals, non-metals, Group 1, Group 7 and Group 0 trends. C9.3 builds word equations, formulae, state symbols and balanced symbol equations through conservation of atoms and mass. C9.5 covers acids, alkalis, pH, indicators, neutralisation, salts, metal oxides, carbonates, crystal preparation and safe practical reasoning. The final four sessions integrate retrieval, concept maps, mixed calculations, data interpretation, practical evaluation, exam strategy and a cumulative 40-question final assessment.
Course Outcomes
By the end of the course, learners can explain matter using macroscopic, particle and symbolic models; choose and evaluate separation methods using physical properties; describe how evidence changed atomic models; calculate particle numbers, isotopic mass and simple chemistry quantities; use electron structure to predict periodic-table patterns; interpret Group 1, Group 7 and Group 0 trends with appropriate safety boundaries; write and balance word and symbol equations without changing formulae; apply conservation of mass to closed and open systems; classify acids and alkalis using ions, indicators and pH; predict neutralisation products and name salts; plan safer methods by identifying variables, controls, apparatus and hazards; analyse tables, graphs and anomalies; use precise chemical vocabulary, formulae, units and state symbols; and revise independently using retrieval, error logs and evidence-based explanations.
