1. Physics · Waves

  1. 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

2. Physics · Fields

  1. Electromagnets: Describe the magnetic effect of an electric current (a current-carrying wire produces a magnetic field), and investigate how the strength of an electromagnet depends on current, number of coil turns, and core material
  2. Motors & the Motor Effect: Explain the motor effect as the force on a current-carrying conductor in a magnetic field, and describe how this principle is used in electric motors and loudspeakers
  3. Newton's First & Second Laws: State and apply Newton's First Law (an object stays at rest or constant velocity unless acted on by a resultant force) and Second Law (force = mass × acceleration), including the relationship between mass, force, and acceleration

3. Physics · Energy

  1. Net Zero & Energy Transition: Evaluate the energy transition required to reach net zero: renewable energy scaling, electrification of transport and heat, green hydrogen; describe carbon capture and storage (CCS) and direct air capture (DAC); introduce proposed solar radiation management techniques (stratospheric aerosol injection, marine cloud brightening) and their potential risks and governance challenges; critically evaluate the role of individual behaviour change versus systemic policy in reducing emissions
  2. 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
  3. Energy stores and transfers: Identify the main energy stores (kinetic, gravitational potential, elastic potential, thermal, chemical, nuclear, electromagnetic) and the pathways by which energy is transferred between stores (mechanically, electrically, by heating, by radiation)
  4. Heating experiments and Q = mcΔT: Plan and carry out experiments to measure energy transferred during heating, including using the equation Q = mcΔT, recording temperature changes over time, and evaluating sources of error

4. Physics · Forces And Interactions

  1. Investigating Forces: Plan and carry out investigations into forces, including measuring force with a newton meter, investigating Hooke's Law, and collecting and interpreting motion data to test Newton's laws

5. Earth and Space Science · Stability And Change In Natural Resources

  1. 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)
  2. Finite Resources & Recycling: Explain that many raw materials (metals, fossil fuels, minerals) are finite resources, describe the environmental costs of extraction, and evaluate the benefits of recycling and the circular economy
  3. 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

6. Earth and Space Science · Patterns In Earth's History And Processes

  1. 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
  2. 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
  3. Reading Ancient Climate Records: Explain how ice cores preserve ancient air bubbles, isotope ratios, and volcanic markers allowing reconstruction of temperature and CO2 going back 800,000 years; describe tree rings, ocean sediment cores, coral skeletons, and pollen records as additional climate proxies; explain how climate models are built and validated against the palaeoclimate record; describe the IPCC process of synthesising scientific evidence across thousands of studies to produce consensus assessments

7. Earth and Space Science · Matter And Energy In Space

  1. Life Cycle of a Star: Describe the life cycle of a star from nebula through main sequence to its end state (white dwarf, neutron star, or black hole depending on mass), and relate the life cycle to the origin of elements heavier than hydrogen

8. Chemistry · Energy In Chemical Systems

  1. 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

9. Chemistry · Stability And Change In Chemical Systems

  1. 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

10. Chemistry · The Structure And Properties Of Molecules

  1. Ceramics, Polymers & Composites: Describe the properties and uses of ceramics (hard, brittle, heat-resistant), polymers (flexible, lightweight, variable), and composites (combine properties of constituent materials), giving real-world examples of each
  2. Pure Substances & Mixtures: Distinguish between pure substances and mixtures, identify formulations as useful mixtures with precise compositions, and use melting and boiling points to test for purity
  3. Metals vs Non-Metals: Compare the physical and chemical properties of metals and non-metals, explaining metallic properties (malleability, lustre, conductivity) and how position in the periodic table predicts reactivity

11. Chemistry · The Structure And Properties Of Atoms

  1. Where Elements Come From: Explain stellar nucleosynthesis: the Big Bang produced mainly hydrogen and helium; main-sequence fusion builds elements up to iron; and supernovae produce elements heavier than iron and scatter them into space — meaning the atoms in our bodies were forged in ancient stars
  2. Radiometric Dating: Explain how radiometric dating works — radioactive isotopes decay at a known rate (half-life), so measuring the ratio of parent to daughter isotope in a rock or fossil gives an absolute age; distinguish between carbon-14 (useful up to ~50,000 years) and uranium-lead (useful for millions to billions of years)
  3. Atoms, Elements & Compounds: Explain the differences between atoms, elements, and compounds; describe the simple Bohr model of the atom (nucleus with protons and neutrons, electrons in shells); and write and interpret chemical symbols and simple formulae

12. Biology · Evolutionary Change

  1. 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
  2. Extinction & Rapid Change: Explain how environmental change can outpace a species' ability to adapt through natural selection, leading to extinction, using historical and contemporary examples
  3. Species Distribution & Change: Explain how environmental change (climate change, habitat loss, pollution) affects the distribution of species, including range shifts, local extinction, and invasive species

13. Biology · Genetic Patterns

  1. 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
  2. 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
