Glacier Power started as a 1997 middle-school curriculum supplement produced by the Alaska Satellite Facility (ASF) in collaboration with glaciologists, local scientists, teachers, students, and artists. Although parts of the supplement have become outdated, several components of Glacier Power are still user favorites and rank among ASF’s most-visited pages.
ASF has updated Glacier Power content in the form of Q&A pages and lesson plans for teachers. Many of the Q&A pages contain vocabulary lists, review questions, or exercises.
