Content Objective: Students will be able to explain different methods for estimating population size, including random sampling, random quadrat sampling for sessile organisms, and capture-mark-release-recapture with the Lincoln index for motile organisms.
Language Objective: Students will be able to design, carry out and analyse data related to one of the sampling methods.

Resources
IA Resource Page - s a comprehensive toolkit for IA (Internal Assessment) preparation, highlighting essential resources like starting points, checklists, and example folders from the old syllabus. It emphasizes the importance of adhering to the IB animal use policy and offers a method for determining outliers using the 1.5x IQR (Interquartile Range) approach. The IA Rubric and Coversheet are vital for assessment guidelines to use AI systems like ChatGPT for feedback.
IA Starting Points - a comprehensive guide for IB Biology students preparing an internal assessment (IA). They detail criteria for different sections including research design, data analysis, conclusion, and evaluation. The notes emphasize the importance of specificity, relevance, and scientific rigor, while also providing insight into formatting considerations and potential pitfalls. It's an essential resource for understanding the expectations and best practices of a high-quality biology IA.
IA Checklist - a comprehensive guide for students creating a lab report for DP Biology. It covers the entire process, from formulating a research question with specific criteria to the evaluation and presentation of findings. It emphasizes clarity, specificity, and scientific rigor. The list ensures that students maintain awareness of safety, ethics, and proper data analysis. Formatting and writing standards are also addressed, ensuring that the report is coherent, concise, and follows specific conventions.
