Grade levels: 9-12

Lesson Objective: The Learner Will Be Able To:

1. Learn about a current research technique that gathers atmospheric and other data from glaciers.
2. Discover what kind of information can be preserved by glacial ice.
3. Research how this technique can effect national and global air quality policies

Materials:

  • Computers with internet access
  • Worksheets (below)
Lesson Process:
1. Introduce the lesson by informing students that the rest of the unit will be focusing on an important research technique being used in many parts of the world, which can provide substantial evidence of the climate record.

2. Hand out research sheets, and help students to navigate to the website. Circulate as students conduct their research. Discuss their answers with them. Ask questions, to make connections with prior learning or to pique curiosity about connections or further research.
