Identify the key components of a drainage basin using precise terminology as pupils explore watersheds, tributaries, confluences and channels through clear diagrams and interactive mapping tasks that build strong geographical vocabulary.

Describe how a river’s long profile changes from source to mouth using visual models that show how gradient, velocity and energy evolve along the river’s journey, helping pupils understand why upper, middle and lower courses behave so differently.

Analyse the relationship between a river’s course and its valley cross‑profile by comparing V‑shaped valleys, wider floodplains and meandering channels, enabling pupils to link fluvial processes directly to landscape form.

This lesson is visually rich, exam‑focused, and easy to teach, giving pupils a secure foundation in drainage basin systems before moving into river processes, landforms and flooding.
