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
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.
Student Research Sheet: Ice Cores
Use the section entitled “Ice Cores: What can they tell us?” from the Climate Change subsection of the Science section of the Mount Logan website to complete this research sheet.
1. What is an “ice core”? What is the point of taking an ice core?
2. What are the three ways in which ice cores preserve information?
3. What are 12 examples of things that can be trapped in ice particles?
4. What kinds of research are ice cores use for? Why?
5. What are two examples in which ice core research has effected global policies? Why do you think that these were important areas of research?
