Extreme Ice

Margy Kuntz, PBS Teachers

This activity students through the ways scientists monitor changes in Earth's glaciers, ice caps, and ice sheets. Students investigate about glacier locations, glacial movement, and impacts of climate change on glaciers depending on the depth of research. It is linked to 2009 PBS Nova program entitled Extreme Ice.

Activity takes two to three 45-minute lesson periods plus time for presentations. Computers with internet access are useful.

Teaching Tips

  • Instructors may want to move the student reading in Step 1 "All About Glaciers" and make it a reference for students for their research on the Internet, Step 4.
  • Create worksheets or scaffolded guides for students to help them conduct more targeted research.
  • Consider having students work in groups during the Internet research component.
  • Provide age-appropriate Internet sites for research (Step 4). Distribute the rubric for the presentations to students ahead of time.
  • This activity is an opportunity to discuss the process of science and how to vet for quality of research and information.
  • Also link to Extreme Ice Survey education section: http://www.extremeicesurvey.org/index.php/education_toc/
  • Other supplemental activities to aid student understanding of glacial processes include the PhET Glaciers Interactive http://phet.colorado.edu/en/simulation/glaciers and the ANDRILL collection of hands-on experiences http://www.andrill.org/flexhibit/flexhibit/materials/activities/index.html.

About the Science

  • Students investigate how scientists monitor changes in Earth's glaciers, ice caps, and ice sheets.
  • This activity relates to the PBS NOVA program on the Extreme Ice Survey, which makes use of time-lapse photography to measure rapid changes in glaciers and ice sheets: http://www.extremeicesurvey.org
  • Refer to NSIDC "All About Glaciers" website for background materials for the teacher and/or interested students: http://nsidc.org/glaciers/

About the Pedagogy

  • The teaching sequence, from eliciting student background knowledge to the final presentation, effectively builds student knowledge about glaciers and how scientists study their changes.
  • Additional structure may help guide students in doing research (Step 4).
  • Building student knowledge about glaciers using related CLEAN selected activities prior to doing this activity would help set the stage, particularly their glacier research.
