Reading Antarctica's Rock Cores
http://www.andrill.org/flexhibit/flexhibit/materials/activities/Unit%203-Reading_Antarctica%27s_Rock_Cores.pdf

LuAnn Dahlman, Andrill

In this activity, students learn about the tools and methods paleoclimatologists use to reconstruct past climates. In constructing sediment cores themselves, students will achieve a very good understanding of the sedimentological interpretation of past climates that scientists can draw from cores.

Activity takes three to four 45-minute class periods with some outside prep and time for exhibit. 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
Environmental observations are the foundation for understanding the climate system. From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.

Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.

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

  • After completing this activity, students will be ready for an in-depth discussion about climate of the past and research methods.
  • These hands-on activities are part of a unit of similar active-learning activities. Teachers should familiarize themselves with those that come before or after.

About the Science

  • Students build models of ice cores and sediment cores to learn about the tools and methods paleoclimatologists use to reconstruct the climate of the past. In constructing sediment cores themselves, students will achieve a very good understanding of the sedimentological interpretations that scientists can draw from a core.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Hands-on activities will engage students of different learning styles.
  • Activities are part of the ANDRILL flexhibit series, which aim at getting students to present the model to others. This can be slightly modified to apply to a general classroom.
  • Nicely scaffolded going from simpler concepts to more sophisticated.
  • Very easy-to-follow procedures.

Technical Details/Ease of Use

  • PDF is designed to be printed double-sided; this explains the blank pages throughout the activity.
