Science
Year 10 · Northern Ireland Curriculum
Year 10 completes Key Stage 3 and in most Northern Ireland schools begins GCSE content. Biology covers cells and transport, enzymes, inheritance, evolution and ecosystems; chemistry covers bonding, the mole, rates, energy changes and organic chemistry basics.
Physics covers forces and motion with equations, energy calculations, electricity, waves, radioactivity and space. Prescribed practicals in the CCEA style are introduced, with formal attention to accuracy, precision and uncertainty.
Schools decide around this point between Double Award Science and separate Biology, Chemistry and Physics GCSEs, so confidence across all three strands keeps every option open.
Important Topics
- Cells, Transport & EnzymesCell structure, diffusion, osmosis, active transport and enzyme action.
- Inheritance & EvolutionDNA, genetic crosses, variation, natural selection and classification.
- Bonding & StructureIonic, covalent and metallic bonding and how structure affects properties.
- Quantitative ChemistryRelative formula mass, the mole and reacting mass calculations.
- Forces & EnergyNewton's laws, momentum, work, power and energy calculations.
- Waves, Electricity & RadioactivityWave properties, circuits, power, radioactive decay and half-life.
- Prescribed PracticalsCCEA-style practicals with attention to accuracy, precision and uncertainty.
