Presentation Transcript

  1. Activator: How would you explain the theory of Pangaea to a group of first graders?

  2. What is an Ice Core? • Cylinder of ice removed from an ice sheet. • Layers of snow become compacted into ice, which are laid atop previous layers of ice to create records of the past. • Like rings of trees in temperate parts of the world, ice layers in polar regions and glaciers also create layered historical records.

  5. Work in pairs to answer the following questions. • Why do scientists drill ice cores? • What makes ice cores so useful for climate research? • Where do you drill them? • How deep are ice cores drilled? • What has so far been discovered with ice core research? • What discoveries have our scientists made? • What tests have to be made before the ice is drilled? • How does the drill work? • What do you do next with the ice cores? • What sore of information can be found out by the analyses?
