1. Life Science

  1. Digestion & Enzymes: Describe the organs of the human digestive system and how food is physically and chemically digested, including the role of enzymes as biological catalysts
  2. Photosynthesis: Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots
  3. Aerobic Respiration: Explain aerobic respiration as the process by which organisms release energy from glucose using oxygen, producing carbon dioxide and water; write and interpret the word equation: glucose + oxygen → carbon dioxide + water
  4. Nutrients in a Healthy Diet: Identify the seven components of a healthy diet — carbohydrates, lipids, proteins, vitamins, minerals, dietary fibre, and water — and explain the role of each in the body
  5. Food Webs & Interdependence: Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others
  6. Biodiversity & Resilience: Explain what biodiversity means, why high biodiversity makes ecosystems more resilient, and describe the ways human activity threatens biodiversity (habitat destruction, pollution, invasive species, climate change)
  7. Renewable vs non-renewable energy: Distinguish between renewable energy resources (solar, wind, hydroelectric, tidal, geothermal, biomass) and non-renewable resources (coal, oil, gas, nuclear), comparing their advantages, disadvantages, and environmental impacts
  8. Earth's Atmosphere & CO2: Describe the composition of Earth's atmosphere (mainly nitrogen and oxygen, with small amounts of CO₂ and other gases), explain how human activity increases CO₂, and describe the impact on global climate
  9. Grouping Species Using DNA: Explain cladistics: organisms are grouped by shared derived characters, not just similarity; how phylogenetic trees are built using molecular data (DNA sequence alignment) and the molecular clock; explain why birds are technically a group within dinosaurs (crown Avemetatarsalia); distinguish convergent evolution (unrelated species evolving similar traits) from parallel evolution; introduce horizontal gene transfer and why the tree of life is more accurately a web; explain why classification systems keep changing as new data emerge
  10. Human Reproduction: Describe the structure and function of the male and female human reproductive systems, and explain the processes of fertilisation, gestation, and birth including the role of the placenta
  11. Cancer & Stem Cells: Explain that cancer occurs when mutations in DNA disable normal cell-cycle controls, causing uncontrolled cell division and tumour formation; describe how stem cells differ from specialised cells and their potential for regenerative medicine; and evaluate the ethical debates around embryonic stem cell research and genetic testing
  12. Genetic Mutation: Explain genetic mutation as a random change in DNA sequence, describe causes of mutation (e.g. radiation, chemicals, copying errors), and explain that most mutations are neutral, some harmful, and a few beneficial
  13. Predicting Inherited Traits: Explain how alleles are inherited in sexual reproduction and use Punnett squares to predict the probability of offspring inheriting a characteristic, including dominant and recessive alleles
  14. How Natural Selection Works: Explain natural selection as the mechanism of evolution: heritable variation + competition for resources + differential survival and reproduction = change in allele frequency over generations
  15. Evidence for Evolution: Describe the main types of evidence for evolution: the fossil record (change over time), comparative anatomy (homologous structures), and the geographic distribution of related species
  16. Plant Reproduction: Describe the structure of a flower and explain the processes of wind and insect pollination, fertilisation, seed and fruit formation, and seed dispersal in plants
  17. Cells Under the Microscope: Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure
  18. Parts of Plant and Animal Cells: Describe the functions of the main components of plant and animal cells: cell wall, cell membrane, cytoplasm, nucleus, vacuole, mitochondria, ribosomes, and chloroplasts

2. Physical Science

  1. Relative Motion: Explain relative motion — how the apparent speed and direction of an object depends on the observer's own motion — using everyday examples such as trains and cars passing
  2. Universal Gravitation: Describe gravity as a universal attractive force between all masses, explain that orbital motion arises because gravity provides the centripetal force keeping objects in orbit, and compare gravitational field strengths on different planets
  3. Newton's Third Law: State and apply Newton's Third Law: every force has an equal and opposite reaction force acting on a different object, distinguishing action-reaction pairs from balanced forces
  4. Reactions That Release or Absorb Heat: Distinguish between exothermic reactions (release energy, temperature rises) and endothermic reactions (absorb energy, temperature falls), with everyday and industrial examples
  5. Conduction, convection, and radiation: Describe and compare the three mechanisms of heat transfer — conduction (particle vibration through solids), convection (fluid movement in liquids/gases), and radiation (infrared waves) — and explain that the rate of transfer depends on temperature difference
  6. Power: watts and energy per second: Define power as the rate of energy transfer (power = energy ÷ time, measured in watts), and compare energy transfer rates in different everyday contexts
  7. Waves & Different Materials: Explain how waves can be absorbed, transmitted, or reflected by different materials, and apply these interactions to explain colour perception, sight, communication technologies, and the effects of different surfaces on wave behaviour
  8. How Materials Change State: Explain melting, freezing, boiling, condensing, and sublimation using the particle model, interpreting heating and cooling curves to identify melting and boiling points
  9. Physical vs Chemical Changes: Distinguish between physical changes (reversible, no new substances formed) and chemical changes (new substances formed, often irreversible), using conservation of mass to understand both types

3. Earth and Space Science

  1. Hurricanes, Tornadoes & Monsoons: Explain how hurricanes form and intensify over warm ocean water (latent heat release, low-pressure spiral); describe tornado formation within supercell thunderstorms; explain monsoon mechanics driven by temperature differences between land and sea; introduce attribution science — how scientists use climate models to calculate whether and by how much climate change increased the probability or intensity of a specific extreme weather event
  2. The Water Cycle: Describe the water cycle, tracing water through evaporation, condensation, precipitation, surface runoff, and transpiration in plants, explaining how the sun drives the cycle
  3. The Carbon Cycle: Describe the carbon cycle, tracing carbon through photosynthesis, respiration, feeding, decomposition, and combustion, and explain the role of each process
  4. How Tectonic Plates Move: Understand that convection currents in the molten mantle drive the movement of rigid tectonic plates; distinguish between convergent (collision/subduction), divergent (spreading ridges), and transform (sliding) plate boundaries; explain why volcanoes, earthquakes, and mountain chains cluster at boundaries; introduce the Wilson cycle of supercontinent assembly and breakup
  5. Galaxies and the universe: Describe the scale of the universe, including the structure of galaxies, the position of the Sun in the Milky Way, and the use of light years as a unit of distance, and appreciate why space exploration requires enormous timescales

4. Nature of Science

  1. Writing Science Reports: Communicate scientific findings in a structured report using appropriate scientific vocabulary, SI units, and standard notation; describe how peer review and replication contribute to the reliability of scientific knowledge
