| | Glacial Topography |
 | | Use diagrams from text or photocopies of diagrams that illustrate a moving glacier and label (or have the students label) the following: tongue of glacier, head of glacier, terminal moraine, lateral moraine, medial moraine, erratic, iceberg, and cirque. |
 | | Have students look at pictures of glaciated topography to see what is left from retreating glaciers including the moraines, erratics, u-shaped valleys, and cirque lakes. |
 | | Divide students into groups that will create models that illustrate the glacial topography of Alaska in various stages: 1: before the glacier, 2: an expanding glacier, 3: a retreating glacier, and 4: the remaining topography after the glacier is gone. |
