Unit 1: How can the diversity of materials be explained?
Students investigate the structures, bonding and properties of covalent compounds, metals, ionic compounds and polymers, and learn quantitative measurement techniques such as empirical formula determination and chromatography. They also explore sustainability concepts—green chemistry principles and the shift from a linear to a circular economy—through a student-directed investigation into more sustainable material production .
Unit 2: How do chemical reactions shape the natural world?
This unit focuses on chemical interactions in water, acid–base and redox reactions, including practical work on specific heat capacity, solubility, molar volume of gases, volumetric analysis and calibration curves. Students hone their hypothesis-driven investigation and data-analysis skills by designing and carrying out a primary-data investigation related to gas production or aqueous analysis .
Unit 3: How can design and innovation help to optimise chemical processes?
Learners quantitatively compare fuels (combustion products and energy outputs), apply the electrochemical series to design and test primary cells and fuel cells, and study reaction kinetics and catalysis to optimise reaction rates. They develop skills in experimental design, critical evaluation of sustainability (e.g. electrolysis processes) and problem-solving in real-world contexts.
Unit 4: How are carbon-based compounds designed for purpose?
Students examine the structure, nomenclature, properties and reactions of organic families (alkanes through carboxylic acids), study synthesis and analysis techniques (functional group tests, titrations, extraction, spectroscopy) and evaluate polymer design and sustainability. They conduct organic-chemistry investigations—such as synthetic pathways and instrumental analysis—while applying green chemistry principles to assess environmental and health impacts
