Grade Level: 6-8
Performance Expectation Connections:
MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.
MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Science and Engineering Practices: Engaging in Argument From Evidence; Analyzing and Interpreting Data
Crosscutting Concepts: Patterns; Cause and Effect
Disciplinary Core Ideas: Adaptation; Interdependent Relationships in Ecosystems; Ecosystem Dynamics, Functioning, and Resilience; Biodiversity and Humans
Possible Guiding Questions: Why is there a treeline? How can certain areas have similar climate but very different vegetation? How have different plants adapted to different elevations? How might climate change impact vegetation patterns on mountains?
Possible Instructional Uses: You may use this phenomenon to explore the relationship between environmental conditions and elevation, life zones, adaptations to different ecosystems, and climate change’s impact on vegetation.

Grade Level: 9-12
Performance Expectation Connections:
HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
HS-LS4-5. Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.
Science and Engineering Practices: Engaging in Argument From Evidence; Analyzing and Interpreting Data; Using Mathematics and Computational Thinking
Crosscutting Concepts: Patterns; Cause and Effect
Disciplinary Core Ideas: Adaptation; Interdependent Relationships in Ecosystems; Ecosystem Dynamics, Functioning, and Resilience; Biodiversity and Humans; Weather and Climate; Global Climate Change
Possible Guiding Questions: Why does treeeline exist on mountains? How does temperature, precipitation, and elevation affect vegetative communities? Why do certain communities of plants grow in certain locations and under certain conditions? How might climate change impact the presence of treeline on mountains? What impacts would a loss of alpine environment have on humans? How might climate change affect the plant communities that we live near?
Possible Instructional Uses: This phenomenon provides an entrance point into discussing how various environmental conditions, such as temperature and precipitation, impact the communities of plants that grow in certain areas. There is also an opportunity to explore how climate change will impact plant communities, including how threats to alpine environments would affect humans.
