Stabilization Wedges Game

Stabilization Wedges Game
https://cmi.princeton.edu/wedges/game

Carbon Mitigation Initiative, Princeton University

This is a team-based activity that teaches students about the scale of the greenhouse gas problem and the technologies that already exist which can dramatically reduce carbon emissions. Students select carbon-cutting strategies to construct a carbon mitigation profile, filling in the wedges of a climate stabilization triangle.

Activity takes about three 45-minute class periods, possibly more with the closure and assessment.

Performance Expectations: 2

HS-ESS3-4: Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

HS-ETS1-3: Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.

Disciplinary Core Ideas: 4

HS-ESS3.A: Natural Resources

HS-ESS3.D1: Though the magnitudes of human impacts are greater than they have ever been, so too are human abilities to model, predict, and manage current and future impacts.

HS-ETS1.B1: When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts.

HS-PS3.A2: At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.

Cross Cutting Concepts: 6

Patterns, Cause and effect, Systems and System Models, Energy and Matter, Structure and Function, Stability and Change

Patterns, Cause and effect, Systems and System Models, Energy and Matter, Structure and Function, Stability and Change

HS-C1.3: Patterns of performance of designed systems can be analyzed and interpreted to reengineer and improve the system.

HS-C2.3: Systems can be designed to cause a desired effect.

HS-C4.4: Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.

HS-C5.3: Energy cannot be created or destroyed—only moves between one place and another place, between objects and/or fields, or between systems.

HS-C6.1: Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem.

HS-C7.4: Systems can be designed for greater or lesser stability.

Science and Engineering Practices: 6

Asking Questions and Defining Problems, Developing and Using Models, Planning and Carrying Out Investigations, Analyzing and Interpreting Data, Using Mathematics and Computational Thinking, Constructing Explanations and Designing Solutions

HS-P1.2: ask questions that arise from examining models or a theory, to clarify and/or seek additional information and relationships.

HS-P2.1: Evaluate merits and limitations of two different models of the same proposed tool, process, mechanism or system in order to select or revise a model that best fits the evidence or design criteria.

HS-P3.5: Make directional hypotheses that specify what happens to a dependent variable when an independent variable is manipulated.

HS-P4.6: Analyze data to identify design features or characteristics of the components of a proposed process or system to optimize it relative to criteria for success.

HS-P5.1: Create and/or revise a computational model or simulation of a phenomenon, designed device, process, or system.

HS-P6.5: Design, evaluate, and/or refine a solution to a complex real-world problem, based on scientific knowledge, student-generated sources of evidence, prioritized criteria, and tradeoff considerations.

Teaching Tips

A large amount of prior knowledge on both the part of the educator and the students is required; having some previous experience with this content is helpful in order to teach/facilitate the lesson. This activity could generate more questions than the background info prepares educators for.
Not all strategies have sufficient background to promote critical discussion; input from educator in these areas could be valuable.
This activity could be used by older students to inform younger students about CO₂ emissions and solutions.

About the Content

Students will learn about the impact CO₂ emissions have on global climate change.
Introduces the concept behind a stabilization triangle (carbon-cutting strategies that can keep the Earth's CO₂ emissions trend "flat"). The strategies presented in this activity are i) efficiency and conservation ii) fossil fuel-based strategies iii) nuclear energy and iv) renewable energy and biostorage.
This activity from the Carbon Mitigation Initiative was a joint project between Princeton University, BP, and Ford.
Comment from expert scientist: The strengths of this activity are not scientific. It's almost exclusively a policy/technology exercise framed by an initial science lesson. It's good at what it does, but it doesn't teach climate science. Understanding available technological solutions and their potential contributions to addressing emissions challenges is an important part of climate literacy.

About the Pedagogy

A good culminating activity for a unit on renewable energy options and climate change. It addresses both the problems and the solutions.
Students will develop reasoning and negotiation skills in order to find a solution and defend it to a larger group; there is no "right" answer.
This activity is based completely in individual choice and so offers opportunities to a diverse group of learners.
Opportunities for adults outside the classroom to become included/engaged with student learning - administrators or community members could judge stabilization triangles.

Technical Details/Ease of Use

Easy to use, clearly written instructions with all necessary handouts provided.
