Google Earth Tours of Glacier Change
http://serc.carleton.edu/NAGTWorkshops/climatechange/activities/21214.html

Mauri Pelto, SERC - On the Cutting Edge Collection

A detailed Google Earth tour of glacier change over the last 50 years is given in class as an introduction. Students are then asked to select from a group of glaciers and create their own Google Earth tour exploring key characteristics and evident changes in that glacier.

Activity takes a minimum of one class period plus some independent work time. Computer access highly recommended.

Teaching Tips

  • If students look at the two glacier tours on their own, they would need a worksheet or other guidance to keep them on track.
  • Educator will have to provide own assessment questions.

About the Science

  • Combines Google Earth imagery, photographs, topographic overlays and data from glaciers and landforms in a lab activity. Powerful way of using Google Earth.
  • Use of many lines of evidence to build an understanding for the effects of climate change on glaciers.
  • The Google Earth tours are loaded with quality information and present data is in several different formats.
  • Comments from expert scientist: The activity provides the students a feel of changes occurring on glaciers due to climate change over the past 50 years. Studying and learning become more effective when you actually start feeling it sensing it, this is what this activity lends.

About the Pedagogy

  • First part of the activity is passive as students watch the Google Earth tour. But the second part of the activity is active and students create their own glacier tour in Google Earth.
  • Students must already be facile Google Earth users as is stated in the activity; this activity would overwhelm new users.
  • Activity can be done independently or guided by educator.
  • The glacier tours can be used as a standalone presentation for students who are not ready to dive into Google Earth and create their own tours.
  • Activity can be done without computer lab based on link in supporting materials.

Technical Details/Ease of Use

  • The .kmz files create a very thorough presentation.

Performance Expectations

HS-ESS3-5: Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth systems.

Disciplinary Core Ideas

HS-ESS2.A3: The geological record shows that changes to global and regional climate can be caused by interactions among changes in the sun’s energy output or Earth’s orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activities. These changes can occur on a variety of time scales from sudden (e.g., volcanic ash clouds) to intermediate (ice ages) to very long-term tectonic cycles.

Science and Engineering Practices

HS-P8.2: Compare, integrate and evaluate sources of information presented in different media or formats (e.g., visually, quantitatively) as well as in words in order to address a scientific question or solve a problem.

HS-P8.3: Gather, read, and evaluate scientific and/or technical information from multiple authoritative sources, assessing the evidence and usefulness of each source.

HS-P8.5: Communicate scientific and/or technical information or ideas (e.g. about phenomena and/or the process of development and the design and performance of a proposed process or system) in multiple formats (i.e., orally, graphically, textually, mathematically).

Cross-Cutting Concepts

HS-C1.5: Empirical evidence is needed to identify patterns.

HS-C2.2: Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.

HS-C6.2: The functions and properties of natural and designed objects and systems can be inferred from their overall structure, the way their components are shaped and used, and the molecular substructures of its various materials.

HS-C7.1: Much of science deals with constructing explanations of how things change and how they remain stable.
