01Scientific questions, evidence and quantitative reasoning
Instrument choice and reading, precision versus accuracy, random versus systematic error, combination of uncertainties, graph plotting and interpretation, and experimental design. Marks come from quoting a correct uncertainty with a sensible number of significant figures and from explaining why a procedure reduces error.
995 words, about 5 min02Matter, materials, reactions and chemical reasoning
This independent foundation chapter develops how the quantum-mechanical model of the atom explains the layout of the periodic table and the trends you are asked to predict: electron configuration, ionisation energy, atomic and ionic radius, electronegativity, and the evidence available from mass spectra and successive ionisation energies. Atomic number Z = protons; mass number A = protons + neutrons; isotopes differ only in neutrons, ions only in electrons.

This mechanics review develops kinematics, Newton's laws, momentum, rigid-body equilibrium, circular motion, oscillations and gravitational ideas. State sign conventions, resolve vectors and justify the choice of force, energy or momentum methods.
1,821 words, about 9 min04Cells, biological regulation, immunity and biotechnology
Cell biology links organelle structure with function, membrane exchange and cell division. This chapter reviews shared foundations and interprets supplied water-potential data.
2,019 words, about 10 min05Earth systems, environmental evidence and space science
This independent teaching chapter develops earth as a system: structure, composition and dynamics. Apply each concept to observable evidence, state the assumptions of calculations, and distinguish a plausible interpretation from a conclusion demonstrated by the data.
4,527 words, about 23 min06Science, technology, policy and ethical reasoning
Science uses observations, models and critical testing to develop explanations. A hypothesis should make empirical predictions that can be checked, but one successful prediction does not prove it beyond all future revision.
