1. Earth and Human Activity

  1. 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

2. Biological Evolution: Unity & Diversity

  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. 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
  3. 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

3. Heredity: Inheritance and Variation of Traits

  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

4. Ecosystems: Interactions, Energy, and Dynamics

  1. 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
  2. The Carbon Cycle: Describe the carbon cycle, tracing carbon through photosynthesis, respiration, feeding, decomposition, and combustion, and explain the role of each process

5. From Molecules to Organisms: Structures & Processes

  1. 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
  2. How the Body Stays in Balance: Explain homeostasis as the process of maintaining a stable internal environment; describe the main feedback loop systems (negative feedback) using blood glucose regulation (insulin/glucagon) and body temperature as concrete examples; and connect the endocrine system (hormone-secreting glands) to the nervous system as two complementary communication systems with different speeds and durations
  3. Cells to Organ Systems: Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism

6. Waves and Their Applications in Technologies for Information Transfer

  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

7. Energy

  1. 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

8. Motion and Stability: Forces and Interactions

  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. 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

9. Matter and Its Interactions

  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
  2. 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
