| Subject: Geography |
| Lesson Topic: River channel processes and landforms: erosion, transport, deposition, flow patterns, landform formation |
Learning Objective/s:
- Describe how hydraulic action, abrasion and solution contribute to river erosion.
- Explain the relationship between discharge, slope and sediment size on transport competence.
- Identify conditions that cause deposition and the landforms that result.
- Distinguish between straight, meandering, braided and anastomosing flow patterns.
- Evaluate flood and erosion hazards based on channel morphology.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint/Google Slides presentation with diagrams
- Handout summarising erosion, transport, deposition processes
- River cross‑section diagram worksheets
- Sample sediment (sand, gravel) for demonstration
- Whiteboard and markers
|
Introduction:
Begin with a striking image of a dramatic river gorge to capture interest. Ask students what factors shape a river’s channel and recall previous lessons on the water cycle. Outline today’s success criteria: students will be able to explain erosion, transport and deposition mechanisms, link flow patterns to landforms, and assess related hazards.
|
Lesson Structure:
- Do‑now (5’) – quick quiz on basic river terminology displayed on board.
- Mini‑lecture (15’) – overview of erosion processes with video clip and diagram.
- Interactive modelling (10’) – students use sand and water trays to observe traction, saltation, and suspension.
- Flow patterns & landforms (15’) – group analysis of the flow‑pattern table and creation of a mind map linking patterns to specific landforms.
- Hazard case study (10’) – examine a recent flood event and identify river‑bank erosion risks.
- Check for understanding (5’) – exit ticket: list three conditions that lead to deposition.
|
Conclusion:
Summarise how erosion, transport and deposition interact to shape river landforms and influence hazards. Students complete an exit ticket matching a flow pattern to its characteristic landform. For homework, they will research a local river and produce a brief report on its dominant processes.
