The Arctic Tundra

Science · Polar Regions · conceptual

Know what the Arctic tundra is — a vast, treeless landscape with permafrost (permanently frozen ground) just below the surface, a very short growing season in summer when mosses, lichens, and tough grasses burst into life, and home to caribou/reindeer, musk oxen, lemmings, and snowy owls

What mastery looks like

  • Describe the tundra as a treeless landscape with permafrost (permanently frozen ground) beneath the surface
  • Explain that the tundra has a very short summer growing season when mosses, lichens, and grasses grow quickly
  • Name at least three tundra animals: caribou/reindeer, musk oxen, lemmings, or snowy owls
