7. Plant Health

  1. 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

8. Plant Structures and Functions

  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

10. Plant and Soil Science

  1. 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

11. Plant Nutrition and Soil Fertility

  1. Diet Imbalance & Deficiency: Explain the health consequences of an imbalanced diet including obesity (excess energy), starvation (severe energy deficit), and deficiency diseases (lack of specific nutrients, e.g. scurvy, rickets)

12. Reproductive Anatomy and Fertility

  1. 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

13. Animal Genetics and Selection

  1. Plant Cells vs Animal Cells: Compare plant and animal cells, identifying shared features and structures unique to plant cells (cell wall, vacuole, chloroplasts)

14. Environmental Science

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

15. Earth And Space Science

  1. 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
  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

16. Biology

  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. Chromosomes, Genes & DNA: Describe the relationship between chromosomes, genes, and DNA in heredity, including the double helix structure of DNA and the historical roles of Watson, Crick, Franklin, and Wilkins
  4. 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
  5. 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
