This link is for a curriculum guide for teaching middle school grades about the geology of Denali National Park and Preserve. Highly recommended to check out. Also the U.S. National Park Service website on glaciers has a lot of information, photos, easy to understand vocabulary, etc.
It includes everything necessary to teach the lessons including vocabulary, AK standards, grading/score sheets, and 8 complete lessons. Some of the lessons include discussions of topics such as glaciers, volcanoes, mountains, faults, and more.
