IBDP Biology Theme B Unit Planners

This detailed IBDP Biology unit planner for Theme B: Form and Function is a complete teaching resource for the 2023 IB Biology syllabus. It covers all sub-topics in Theme B (B1.1 to B4.2), including carbohydrates and lipids, proteins and enzymes, membranes and membrane transport, organelles and compartmentalization, cell specialization, gas exchange, transport (blood and plant), muscle and motility (HL), adaptation to environment, and ecological niches.
Designed for both SL and HL, the planner includes a suggested teaching sequence, clear learning objectives aligned to the IB guide, key concepts, ATL skill development, engaging inquiry activities, practical investigations (e.g., enzyme experiments, osmosis, transpiration), formative and summative assessments, differentiation strategies, Nature of Science links, and strong cross-theme connections.
How to use it in the classroom:

Follow the ready-to-adapt scheme of work for approximately 7–9 weeks of teaching.
Use it to plan lessons, practical work, and assessments efficiently.
Help students understand the core idea that biological structures are adapted to perform specific functions at molecular, cellular, and organism levels.
Build exam readiness with targeted practice questions and internal assessment support.

Ideal for experienced IB educators and teachers new to the updated syllabus, this resource significantly reduces planning time while ensuring complete syllabus coverage and high-quality pedagogy. Supplied in editable format for easy customisation.
