Biology

Course summary

The rationale behind the Biology course is to develop in pupils a broad, general understanding of the underlying principles of the subject. The course is arranged in four themes: • Theme A: Unity and diversity • Theme B: Form and function • Theme C: Interaction and Interdependence • Theme D: Continuity and change Each theme is arranged into four different levels of organisation: • Level 1: Molecules • Level 2: Cells • Level 3: Organisms • Level 4: Ecosystems Throughout the course, there are ‘Linking Questions’, which are designed to encourage students to make connections between topics and levels. Both SL and HL students will study all four themes and levels of organisation, but HL students will study a greater breadth and depth. In addition to theoretical knowledge, students will also develop experimental, technological and mathematical skills through practical investigation work, including an individual investigation, which forms the Internal Assessment.
