Avalanche!

Viewing Ideas


Before Watching

  1. Avalanche researchers need to be concerned with a wide range of variables including the kind of snow that falls (such as light, dry, or wet), and the cumulative layering of snow on any hillside. As they watch the program, have students develop a list of properties of snow, the kind of environmental factors that might shape how layers of snow pack together, and the kinds of snow that fall.

After Watching

  1. Have students continue discussing the characteristics and properties of snow and how scientists use this information in avalanche research. What kinds of environmental factors might influence how layers of snow fall? What kinds of snowpack layers indicate an area is at high risk for avalanches? How do people who have seen or been caught in avalanches describe how the snow changes before, during, and after an avalanche?
