In this activity, students investigate how scientists monitor changes in Earth's glaciers, ice caps, and ice sheets. The activity is linked to 2009 PBS Nova program entitled Extreme Ice.

This activity uses a mix of multimedia resources and hands-on activities to support a storyline of investigation into melting sea and land ice.

This activity allows students to examine graphs of sea level rise data as well as global temperature data. They calculate amounts and rates of sea level rise for various time periods and answer questions discussing the data. They then compare the sea level rise trends to those in a graph of temperature data.
