LuAnn Dahlman, Antarctica's Climate Secrets: Project Andrill

In this activity, students chart temperature changes over time in Antarctica's paleoclimate history by reading rock cores. Students use their data to create an interactive display illustrating how Antarctica's climate timeline can be interpreted from ANDRILL rock cores.

Activity takes three 45- to 50-minute class periods. Additional materials required.

Climate Literacy
About Teaching Climate Literacy

Scientific observations indicate that global climate has changed in the past, is changing now, and will change in the future. The magnitude and direction of this change is not the same at all locations on Earth.
About Teaching Principle 4
Other materials addressing 4d
Based on evidence from tree rings, other natural records, and scientific observations made around the world, Earth’s average temperature is now warmer than it has been for at least the past 1,300 years. Average temperatures have increased markedly in the past 50 years, especially in the North Polar Region.

Benchmarks for Science Literacy
Learn more about the Benchmarks

The earth's climates have changed in the past, are currently changing, and are expected to change in the future, primarily due to changes in the amount of light reaching places on the earth and the composition of the atmosphere. The burning of fossil fuels in the last century has increased the amount of greenhouse gases in the atmosphere, which has contributed to Earth's warming.

Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Activity can be done by the entire class or perhaps two or three groups to give students opportunities for building and analyzing their own display.
  • This activity is part of the ANDRILL Flexibit suite of activities. Teacher may wish to have one student group build this interactive and present to other students while other student groups build and present other interactives in the suite.
  • For a simpler version of this activity, teacher may wish to omit the PVC structure of the interactive and have students focus on the core cards.
  • Note that the PDF file is formatted to be printed double-sided. There are blank pages inserted in places where cards and images will need to print single-sided.

About the Science

  • An excellent use of models to illustrate how scientists determine the nature of past climate history.
  • Students build a graphic depiction of Antarctica's climate history.
  • Students examine different layers in rock cores - e.g. diamictite transitional layered rocks and volcanic ash - for evidence of warm and cool climates in Anarctica's past climate history.
  • Focus is on authentic research and data.
  • Comment from expert scientist: Provides a good brief summary of earth's temperature fluctuations in last 40 million years, including a brief introduction of some of the mechanisms contributing to those changes.

About the Pedagogy

  • The illustrated directions for students are exceptionally well done and each step is accompanied by excellent images to guide students.
  • Student handouts are very well done, particularly the core cards. Excellent introductory reading for students.
  • This is a project-based, hands-on group activity that asks student to create an interactive display of rock core evidence for climate change. By having to guide and explain visitors as they interact with the display, students will further consolidate their understanding of the core science content.
  • The teacher may wish to spend additional time reinforcing the concept that rock types in cores indicate past environments, which indicate past climate. For a given location, rock types change as environments/climate change over time.
  • For a more in-depth exploration, especially with more advanced students, see Earth Exploration Toolkit activity: http://serc.carleton.edu/eet/cores/index.html

Technical Details/Ease of Use

  • The teacher guide, leader notes in this case, for all the Andrill activities is housed at a separate site: http://www.andrill.org/flexhibit/flexhibit/materials/activities/Leader_Notes.pdf.
  • Students should have no problem following the clear and well-written directions.
  • Teachers may wish to visit the ANDRILL web site for additional background information about the research and Antarctica's climate history.
