This complete bundle contains all 10 DP Biology unit planners for Theme B: Form and Function. Designed for a combined SL/HL classroom in Year 1, Term 1–2.

What’s inside the bundle?

10 complete unit planners – B1.1 Carbohydrates and Lipids, B1.2 Proteins, B2.1 Membranes and Membrane Transport, B2.2 Organelles and Compartmentalisation, B2.3 Cell Specialisation, B3.1 Gas Exchange, B3.2 Transport, B3.3 Muscle and Motility (HL), B4.1 Adaptation to Environment, B4.2 Ecological Niches.

A free unit plan on B2.1 Membranes and Membrane Transport

Teaching sequence – Units in order with SL/HL differentiation, teaching time, prior knowledge links (from Theme A), and forward links to Themes C and D.

Detailed activities – Prior knowledge elicitation, food tests practical, membrane permeability prediction, osmosis practical (potato – % mass change, error bars, isotonic point), fluid mosaic model AoS drawing (12-point IB checklist), organelle role-play, cell specialisation case studies, lung volume measurement (spirometer), stomatal density investigation (nail varnish casts), transect fieldwork, goniometer joint ROM measurement, skull/dentition analysis, competitive exclusion simulation.

Assessment – Formative (exit tickets, diagram peer assessment, practical data analysis, AoS drawing checklist) and Summative (end-of-unit tests: MCQ + data-based + extended response; end-of-theme test covering B1–B4).

NOS connections – Paradigm shift (fluid mosaic model), technology enabling discovery (aquaporins – Nobel 2003, cryo-EM), correlation vs causation, deductions from theories (dentition–diet), co-evolutionary arms races, competitive exclusion as falsifiable principle.

ATL skills – Thinking (structure–function reasoning, systems thinking), Social (collaborative practicals, peer assessment), Communication (AoS drawings, extended writing, error bars), Self-management (practical time management), Research (PDB investigations, citizen science).

Cross-curricular links – TOK (models in science, reductionism), Language and Learning (bilingual English–Mandarin vocabulary), CAS (osmosis citizen science, patient education leaflets, biodiversity surveys).

Differentiation – Scaffolding (decision flowcharts, templates, partial diagrams), affirming identity (SGLT2 inhibitors and diabetes in China – ~140 million patients; TCM connections; ABO blood group; Chinese marine mammals), extension (PDB structures, homeoviscous adaptation, organoids, SNARE proteins).

Common misconceptions registers – Teacher reference from IB Examiner Reports for every unit.
