One of the most important indicators of our warming climate is the extent and thickness of polar sea ice. Currently satellites measure the extent of polar sea ice but it takes more sophisticated equipment aboard a low-flying plane to actually measure the thickness of sea ice. This lesson will show students how this is done.
This lesson/project/lab has students predict via multiple drawings and time lapse photography predictive Flubber flow before the placement of barriers and other obstacles in front of the Flubber. Contour lines in two directions are drawn on both the paper prediction and the Flubber for comparison purposes.
Following predictive drawing completion glacier flow (Flubber flow), with obstacles in place
Ground penetrating radar is an important tool for studying glacier dynamics. Glacier scientists use GPR images to analyze attributes of glaciers. The following research activity will familiarize students with the basics of the different types of glaciers and their dynamics along with ground penetrating radar and its use in glacier studies.
