Cambridge Progression Test Stage 8 Science 2025 Paper 2

1. Human biology and health: blood components and functions, gas exchange (diffusion), respiration vs breathing, dietary needs for muscles and bones, cancer causes (lifestyle, genetics)
2. Chemistry and physics: atomic structure (Rutherford model, nucleus composition), electromagnet use, Earth′s magnetism (core currents), exo/endothermic reactions, sodium in water reaction
3. Data and investigation: temperature change recording, anomalous result identification, energy content experiment in foods, solubility vs temperature graph plotting and trend description
4. Ecosystems and space: objects in galaxies (stars, planets, etc.), electromagnetic strength testing (fair test, reliability), climate vs weather classification, greenhouse gas sources
5. Light and energy: white light dispersion (prism), additive color mixing (light colors), renewable vs non-renewable energy (solar, wind vs fossil fuels), solar panel usage
6. Science skills: analogies (concentration model), interpretation of distance-time graphs (race outcome, speed), reliability of results, concept of model application in science
