March of the Polar Bears: Global Change, Sea Ice, and Wildlife Migration

Type of Resource



In this activity students use NASA satellite data to study changes in temperature and snow-ice coverage in the South Beaufort Sea, Alaska. They will then correlate the data with USGS ground tracking of polar bears and relate their findings to global change, sea ice changes, and polar bear migration and survival.

Performance Expectations

HS-LS2-6   Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

HS-ESS3-6   Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity.

MS-LS2-4   Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
