Progression Test Stage 9 Science 2025 Paper 1

1. Ecosystem changes due to temperature and predators, trophic interactions, population dynamics, natural selection
2. Periodic Table analysis (periods, groups), electronic configuration classification, group trends, element identification
3. Waveform interpretation for distance sensing, sound wave changes in frequency and amplitude, electrical current in parallel circuits, circuit diagram construction
4. Plate tectonics (mantle convection, continental drift, fossil evidence), Atlantic spreading, density graph plotting, water-ice density comparison
5. Cell structure and nucleus labeling, DNA as characteristic-determining structure, carbon cycle (combustion, respiration, decomposition), making crystals from neutralisation
6. Moon formation via collision theory (evidence sequencing), kidney function analogy (strength/limitation), combustion rate experiment (hypothesis, variable measurement), temperature vs heat model explanation (mass and energy)
