Drainage Basin System - Complete KS3 Geography Lesson Pack

🎒 Everything you need to teach the drainage basin system at KS3 — two complete resources, full answer keys, and no preparation required. This lesson pack covers inputs, outputs, stores, flows and flood risk for students aged 11-14.

A drainage basin is the area of land that a river and its tributaries collect water from. Geographers treat it as an open system, because water enters it as inputs and leaves it as outputs.

📝 The main worksheet contains 16 questions worth 100 marks across three progressive sections: recall through multiple choice, true/false and a word bank summary (30 marks); definitions, a classification table and short written answers on routes to the river (40 marks); and extended writing on flood risk, a housing estate scenario and a two-basin comparison (30 marks). The extension pack provides four enrichment activities — vocabulary matching (12 marks), a challenge quiz (25 marks), a Pickering Slowing the Flow case study (20 marks) and a rubric-assessed Teach It Back guide. Full answer keys are included for everything. Everything comes as a PDF and an editable Word file (DOCX).
