Active learning ideas
Glaciation and the British Landscape examines how the massive ice sheets of the Pleistocene shaped the topography of Great Britain. Students learn to identify landforms of erosion, such as corries, arêtes, and U-shaped valleys, and landforms of deposition like moraines and drumlins. This topic is central to the AQA Geography specification and provides a geological context for the UK's dramatic northern landscapes.
Activity 01
Groups are given topographic maps of the Lake District or Snowdonia. They must use highlighters to identify glacial features (e.g., ribbon lakes, hanging valleys) and then present a 'geological tour' explaining how the ice created that specific landscape.
How do glaciers erode, transport, and deposit material?
Activity 02
Students use a mixture of flour and sand to simulate a glacier moving down a cardboard 'valley'. They observe how the 'ice' plucks material from the sides and deposits it at the 'snout', creating miniature moraines and showing how glaciers transport debris.
What key glacial landforms are visible in the UK today?
Activity 03
Students look at photos of a U-shaped valley and a rugged arête. In pairs, they discuss which area is better for building a road, a farm, or a reservoir, and why the glacial shape of the land makes these decisions easier or harder.
How has glacial topography influenced human agriculture and settlement?
A few notes on teaching this unit
Watch Out for These Misconceptions
Glaciers melt to move.
Glaciers move primarily through 'internal deformation' (flowing like very thick honey) and 'basal sliding' (sliding on a thin layer of meltwater). Using a 'flour glacier' model helps students see that ice can flow even when it is solid.
The UK is still in an Ice Age.
We are currently in an 'interglacial' period of the Quaternary. Peer discussion about current ice retreat in the Alps or Arctic helps students understand that the UK's glacial features are 'relics' of a colder past.
Methods used in this brief
Weathering, Erosion, and Sedimentary Environments
Examining the physical and chemical breakdown of rocks and the transport of sediments. Pupils will link these processes to the formation of distinct sedimentary landscapes.
8 methodologies
Coastal Processes and Human Interaction
Investigating the dynamic nature of coastlines through erosion and deposition. Pupils will evaluate historical and modern strategies for coastal management and defence.
