Objectives (Students will be able to do some or all of these depending on grade level and weather conditions):
- Tell what national parks protect, one reason Glacier National Park was established, and name another national park in the United States.
- Assemble a puzzle-map of the Crown of the Continent Ecosystem and explain why it is important that neighbors work together toward shared goals.
- Record temperatures of: the air; the top, middle and bottom of a snow pit; and compare/contrast them.
- Recognize track patterns and record wildlife signs/sightings.
- Match winter twig samples and identify them using a dichotomous key.
- Map or sketch the dominant vegetation types along the trail.
- Use a topographic map to locate Marias Pass, East Glacier, the Blackfeet Reservation, Lewis and Clark National Forest, Glacier National Park, and Three Bears Lake.
- Explain why there are two earthen dams on the edges of Three Bears Lake.
- Tell what a snow survey course is and its significance to people living in the watersheds originating in Glacier National Park.
- Name the 5 factors that make winter difficult for living organisms to survive (SCREW factors) and give 2 examples of organisms’ adaptations to cope with some of these factors.
- Dig a snow pit and collect snow cores from the top, middle, and bottom layers, calculate the snow water equivalent for each sample, and analyze the results.
- Closely observe snowflake shapes and use a classification system to document the dominant type of shape present in the snow pack surface layer.
- Use the words subnivean and supranivean environments and describe where they are found and an animal that lives in each.
- Name the snow structure that has been used by different cultures as a temporary shelter (quinzhee), describe how to build it, and explain why it is warmer inside than outside one.
Montana Content and Performance Standards:
MT.SCI.K-12.1 Students, through the inquiry process, demonstrate the ability to design, conduct, evaluate, and communicate results and reasonable conclusions of scientific investigations.
MT.SCI.K-12.2 Students, through the inquiry process, demonstrate knowledge of the properties, forms, changes, and interactions of physical and chemical systems.
MT.SCI.K-12.3 Students, through the inquiry process, demonstrate knowledge of characteristics, structures and function of living things, the process and diversity of life, and how living organisms interact with each other and their environment.
Making Connections to Glacier National Park:
Glacier National Park protects habitat and natural processes with little human disturbance. In winter, this habitat changes drastically and winter ecologists can study the inter-relationships and adaptations of organisms which allow them to cope with these factors in order to survive.
