The image above shows a road map for navigating the "Arctic Feedbacks" curriculum. Students are introduced to the anchoring phenomenon in lesson 1, engage in sense-making activities in lessons 2-8, and demonstrate their learning by constructing a final model and written explanation in lessons 9-10.
Lesson Descriptions
Lesson 1: Eliciting Ideas About a Phenomenon
In this lesson, students work in pairs to construct initial descriptive models and explanations for the unit driving question, “why is the Arctic warming twice as fast as the rest of the world?”
- Driving Question(s):
- Why should we care about the Arctic?
- Learning Goal(s):
- Define and describe the geography of the Arctic
- Elicit student ideas why the Arctic might be warming twice as fast as the rest of the world.
- Standards:
- ESS2.A: Earth Materials and Systems & ESS2.D: Weather and Climate
Lesson 2: Earth's Energy Budget
In this lesson, students will identify and describe properties of the electromagnetic spectrum in the context of Earth’s energy budget.
- Driving Question(s):
- How does Earth maintain the perfect balance of incoming and outgoing energy?

- Create a conceptual model that represents Earth’s energy budget
- Standards:
- ESS2.D: Weather and Climate
Lesson 3: Greenhouse Effect
In this lesson, students explore the relationship between shortwave/longwave energy and atmospheric gases through a simulation and predict how changes in greenhouse gas concentrations will affect global temperatures.
- Driving Question(s):
- What characteristics define a greenhouse gas?

Lesson 4: Arctic Fieldwork
In this lesson, students visit MOSAiC field sites through virtual reality Google Expeditions and interact with actual shortwave and longwave energy datasets from the Arctic to understand how the Arctic energy budget has changed over time.
- Driving Question(s):
- What scientific instruments are MOSAiC scientists using to study the changing Arctic climate system?
- How has the amount of incoming shortwave energy and outgoing longwave energy changed over time?
- Learning Goal(s):
- Identify patterns in shortwave and longwave energy over time.
- Develop scientific questions related to shortwave and longwave energy datasets.

Lesson 5: Model Revision
In this lesson, students draw on concepts and evidence acquired during the unit to revise their initial models, constructing a new model for the phenomenon, “Why is the Arctic warming twice as fast as the rest of the world?”
- Driving Question(s):
- Why do scientists continue to gather evidence and revise models of phenomenon?
- Learning Goal(s):
- Reflect on learning by applying evidence gathered from previous lessons to revise initial models/explanations.
- Standards:
- ESS2.D: Weather and Climate
Lesson 6: Measuring Albedo
In this lesson, students will use the “Albedo: A Reflectance App” to measure the reflectance (albedo) of different surfaces and come up with a rule to describe the relationship between the color of a surface and its albedo.
- Driving Question(s):
- What is the relationship between the color of a surface and its albedo?
- What happens to energy that is not reflected by a surface?
- How could a decline in sea ice affect the Arctic’s albedo and temperature?
- Learning Goal(s):
- Describe the relationship between the color and albedo
- Describe the relationship between albedo and temperature
- Standards:
- ESS2.A: Earth Materials and Systems
Lesson 7: Ice-Albedo Feedback
In this lesson, students analyze maps to calculate and compare changes in the Arctic’s albedo.
- Driving Question(s):
- What is a feedback loop?
- How does a decline in sea ice lead to further melting of sea ice?
- Learning Goal(s):
- Describe the ice-albedo feedback loop
- Standards:
- ESS2.A: Earth Materials and Systems
Lesson 8: Model Testing
In this lesson, students will test their models by matching their ideas against real-world data about the phenomenon, Arctic amplification.
- Driving Question(s):
- Can we use real-world data to confirm or refute our model/understanding of the unit driving question?
- Learning Goal(s):
- Identify and explain patterns in data
- Standards:
- ESS2.A: Earth Materials and Systems & ESS2.D: Weather and Climate
Lesson 9: Final Model Construction
In this lesson, students draw on concepts and evidence acquired during the unit to construct final models for the unit driving question, “Why might the Arctic be warming twice as fast as the rest of the world?”
- Driving Question(s):
- Why do scientists continue to gather evidence and revise models of phenomena?
- Learning Goal(s):
- Construct a final model that explains why the Arctic is warming twice as fast as the rest of the world
- Standards:
- ESS2.A: Earth Materials and Systems & ESS2.D: Weather and Climate
Lesson 10: Final Explanation
In this lesson, students work independently to write their final evidence-based explanations for the unit driving question,“Why is the Arctic warming twice as fast as the rest of the world?
- Driving Question(s):
- Why might the Arctic be warming twice as fast as the rest of the world?
- Learning Goal(s):
- Construct a written explanation for the unit driving question, why is the Arctic warming twice as fast as the rest of the world?
- Standards:
- ESS2.A: Earth Materials and Systems & ESS2.D: Weather and Climate
