River Landforms: Upper Course

Active learning works well for river landforms in the upper course because students need to see erosion processes in action. Hands-on modeling and simulation let learners connect abstract erosion concepts to visible changes in landform shape over time.

Activity 01

• 45 min · Small Groups

Stream Table Simulation: V-Shaped Valleys

Provide stream tables with layered sand and gravel. Students add water from a height to mimic upper course flow, then measure and sketch cross-profiles before and after 10 minutes of erosion. Discuss how vertical cutting forms the V-shape.

Explain how a V-shaped valley is formed through vertical erosion.

Facilitation Tip

During the Stream Table Simulation, circulate with a ruler to prompt students to measure channel depth changes at 2-minute intervals.

What to look for

Provide students with a diagram of a V-shaped valley and a waterfall. Ask them to label three key landforms and write one sentence explaining how differential erosion contributes to the formation of the waterfall.

Activity 02

Clay Model: Waterfalls and Gorges

Groups layer modeling clay with soft base and hard caprock. Pour water to erode the softer layer, observing undercutting and retreat. Record changes with time-lapse photos and explain gorge formation.

Analyze the conditions necessary for the formation of a waterfall and gorge.

Facilitation Tip

When students build clay models of waterfalls, ask them to scrape away layers to observe undercutting and plunge pool formation in real time.

What to look for

Ask students to complete a 'Think-Pair-Share' activity. Pose the question: 'How does the type of rock influence the shape of an upper course river valley?' Students first think individually, then discuss with a partner, and finally share their ideas with the class.

Carousel Review: UK River Case Studies

Set up stations for rivers like the Tees or Upper Severn with maps, photos, and geology data. Groups spend 7 minutes per station annotating landforms and predicting changes, then share findings.

Predict how the geology of an area influences the development of upper course landforms.

Facilitation Tip

For the Carousel Review, place UK case study maps at stations and invite students to rotate in small groups, annotating erosion features directly on the maps.

What to look for

Facilitate a class discussion using the prompt: 'Imagine you are a geologist surveying a newly discovered river system. What geological features would you look for to determine if it is in its upper course, and why are these features significant?'

Geology Prediction Challenge: Individual Mapping

Provide cross-sections of rock types. Students draw predicted upper course landforms and justify with erosion rates. Peer review follows to refine predictions.

Explain how a V-shaped valley is formed through vertical erosion.

Facilitation Tip

During the Geology Prediction Challenge, have students trace rock layers on tracing paper to predict where softer rock will erode fastest along their mapped river sections.

Provide students with a diagram of a V-shaped valley and a waterfall. Ask them to label three key landforms and write one sentence explaining how differential erosion contributes to the formation of the waterfall.

A few notes on teaching this unit

Teachers should emphasize process over product. Avoid rushing to labeling exercises—instead, let students observe erosion over minutes, not days, through simulations. Avoid showing images of completed landforms first; let students build understanding through iterative modeling and measurement. Research suggests tactile modeling improves spatial reasoning in geomorphology, so prioritize activities where students manipulate materials to see cause-and-effect relationships.

Students will accurately describe how steep gradients and vertical erosion shape V-shaped valleys, waterfalls, and interlocking spurs. They will also explain how rock resistance and mass movement contribute to landform development in the upper course.

Watch Out for These Misconceptions

• During Stream Table Simulation: V-Shaped Valleys, watch for students assuming lateral erosion dominates because valley walls appear wide.

  After students observe the stream table for 5 minutes, ask them to measure the depth change at the center versus the sides, then compare width changes to depth changes in their lab notes.

• During Clay Model: Waterfalls and Gorges, watch for students believing waterfalls form randomly or due to external forces like earthquakes.

  Prompt students to label rock layers with hardness ratings before modeling, then measure the undercutting distance after each scrape to connect rock type to erosion rate.

• During Carousel Review: UK River Case Studies, watch for students thinking interlocking spurs are temporary features that quickly erode away.

  Ask students to trace the outline of spurs on Ordnance Survey maps and calculate the distance between spurs to demonstrate their persistence over long time scales.
