  It covers the following topics:

  • Section A
    • Science careers and scientific investigations — careers requiring General Science; defining "inference"
    • Microscopy and cell biology — parts of the microscope (diaphragm, objective lens); cell components (cytoplasm, ribosome); light vs. electron microscope
    • Human digestion — where mechanical digestion begins, stomach enzyme for protein digestion, adaptations of the ileum

    • Plant biology — conditions for seed germination, types of germination, translocation tissue (phloem), hormone for apical dominance (auxin)
    • Chemistry — acid-base identification, salt formation (magnesium + HCl), deliquescence, factors affecting rate of chemical reactions
  • Section B
    • Cell biology and microscopy — detailed study of cell organelles and their functions
    • Human digestive system — structure and function including enzyme action
    • Chemistry — properties of substances, chemical bonding, salt chemistry
    • Plant physiology — germination, transport systems, and plant hormones in greater depth
