In this lesson students interpret USGS data in multiple formats and draw conclusions based on the data presented. Oblique repeat photographs, satellite imagery, and tables of glacier area change from Glacier National Park, Montana, are presented and the concept of "qualitative and quantitative data" is explored. Students draw conclusions based on the data provided and extension lessons allow them to draw relationships between CO2 emissions, climate trends, and glacier recession. Students share their observations and make linkages about climate and impacts. 

NGSS Alignment:



Students will be able to:

  1. Interpret information from multiple formats
  2. Understand the benefits and limitations of certain types of data representations
  3. Understand how area data is obtained for glacier analysis and appreciate some of the skills and challenges in analyzing aerial imagery
