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, the routes rain takes to a river 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 - a 12-term vocabulary matching exercise (12 marks), a challenge quiz with a river-level data table (25 marks), a Slowing the Flow case study on Pickering in North Yorkshire (20 marks) and a Teach It Back guide for a Year 5 pupil (rubric-assessed). Full answer keys and detailed marking guidance are included for everything. Everything comes as a PDF and an editable Word file (DOCX).

Buying this bundle saves £1 compared to purchasing both resources separately (£3 + £3 = £6 individually, £5 as a pack).

Google Classroom ready.
