Glaciers also change landscape by sanding rocks that are attached to the base of a glacier’s bedrock. Scraping is evident in grooves on rock surfaces called glacial striations; the sand and silt left behind is called till. In this lesson, students will make a model of a glacier and discover how a glacier moves rocks and soil.
This resource is explicitly designed to build towards this science and engineering practice. In this lesson, students conduct an investigation to explain how glaciers change the land. Have the students make predictions and record them in their journals. Allow students to share their thinking and record initial thoughts before investigating.

Frequent Questions – 💬
❓ What is a glacial landscape?
Glaciers are the cold and artistic architects of the lay of many lands. Most hills and valleys are carved by glaciers in the cooler regions of earth, and often the scenery includes lakes, peaks, rich soils in river valleys and more. A glacier is a river flowing downhill.
❓ How do Glaciers form landforms?
The rocks in the foreground were dropped by a retreating glacier, and the mountains in the background have been carved by glacial action. Glaciers can sculpt and carve landscapes by eroding the land beneath them and by depositing rocks and sediment. This diagram shows how glaciers can erode bedrock.
❓ How do Glaciers erode and carve land?
Glaciers can sculpt and carve landscapes by eroding the land beneath them and by depositing rocks and sediment. This diagram shows how glaciers can erode bedrock. Abrasion involves scratching the bedrock with debris in the basal ice.
❓ How do glaciers affect the landscape?
Glaciers carve so much of the landscape, that together with volcanic action, they are responsible for the land as it is found today be it suited for forests, farming, or recreational wilderness that sustains all ecosystems of earth.
