3.7.2.4 Population growth PART 2

3.7.2.1–3.7.2.4 Populations in ecosystems
3.7.2.1 Populations and communities
3.7.2.2 Adaptations and niches
3.7.2.3 Investigating populations

• Builds directly on prior learning to develop a deeper understanding of population growth, carrying capacity, and limiting factors (abiotic & biotic)
• Explicit teaching of population growth curves (lag, exponential, stationary, decline) with clear biological explanations
• Strong focus on interpreting and applying data, including logarithms and log scales in biological contexts
• Active retrieval embedded throughout (MWBs, starter exam questions, structured FNT approach)
• Exam practice at the core: students complete and annotate AQA-style questions, supported by mark schemes and examiner reports to model high-level responses
• Addresses key misconceptions (e.g. exponential growth vs linear, reproduction vs survival, correlation vs causation)
• Develops disciplinary thinking: explaining trends, evaluating conclusions, and linking evidence to biological principles
• Integrates maths skills (log/ln, data conversion, graph interpretation) in a meaningful biological context
• Designed to support A–A* students through precise terminology, structured explanations, and synoptic links
