Lesson 4: Tundra
Duration of Days: 4
Lesson Objective
Describe the impact of permafrost on vegetation and the short growing season of the Arctic.
What defines a tundra biome (climate, vegetation, soil, and landscape)?
How long is the growing season in the tundra, and what are the effects of 24-hour sunlight in summer?
How does global warming affect the tundra, including the melting of permafrost and the northward migration of tree species?
HS-ESS2-2: Analyze geosphere/biosphere interactions.
Identifying positive feedback loops in scientific texts (e.g., warmer temps, less ice, more heat absorbed).
Investigation of the Arctic and Alpine Tundra, focusing on permafrost and the unique challenges of a short growing season.

See "Materials / Resources / Text / Speakers" field
Students create a visual showing how permafrost affects root growth and how climate-driven melting (albedo effect) creates a positive feedback loop for warming.
