About This Topic

Global Sustainability & Our Future serves as the capstone for the 7th grade geography curriculum, challenging students to use everything they have learned to solve the world's most pressing issues. Students explore the concept of 'global citizenship' and how geographic thinking can be applied to challenges like climate change, resource inequality, and sustainable urban planning. The unit emphasizes the role of technology and personal action in creating a more equitable and healthy world.

This topic is the ultimate application of geographic analysis. It aligns with standards regarding the use of geographic tools to solve problems and the role of individuals in a globalized society. This topic comes alive when students can physically model the patterns of a sustainable future through collaborative problem-solving and action planning.

Key Questions

1. Explain why Antarctica is the only continent without permanent human residents or sovereign government.
2. Analyze how the Antarctic Treaty exemplifies international cooperation for scientific purposes.
3. Predict the global impacts of melting polar ice caps on coastal cities worldwide.

Learning Objectives

• Analyze the unique governance structure of Antarctica established by the Antarctic Treaty System.
• Explain the role of Antarctica as a global climate monitoring station, identifying key scientific research conducted there.
• Evaluate the potential consequences of Antarctic ice melt on global sea levels and coastal communities.
• Compare the ecological characteristics of Antarctica with other continents, focusing on its lack of permanent human settlement.
• Synthesize information to propose solutions for mitigating the impacts of climate change on Antarctic ecosystems.

Before You Start

Continents and Oceans

Why: Students need a foundational understanding of Earth's major landmasses and bodies of water to place Antarctica geographically.

Introduction to Climate and Weather

Why: Understanding basic climate concepts is necessary to grasp Antarctica's role in global climate studies and the impact of ice melt.

Forms of Government

Why: Prior knowledge of different governmental structures helps students analyze the unique governance model of Antarctica.

Key Vocabulary

Antarctic Treaty System	A collection of international agreements that designates Antarctica as a continent for peace and science, prohibiting military activity and promoting scientific cooperation.
Sovereignty	The supreme authority within a territory, typically referring to the right of a state to govern itself. Antarctica has no single sovereign nation.
Scientific Preserve	An area designated for scientific research and environmental protection, where human activity is carefully managed to minimize impact.
Ice Sheet	A vast, permanent layer of ice covering a landmass, such as those found in Antarctica, which holds a significant portion of the world's freshwater.
Climate Proxy	Natural archives, like ice cores, that preserve historical climate information, allowing scientists to study past atmospheric conditions.

Watch Out for These Misconceptions

Common Misconception

Global problems are too big for one person to make a difference.

What to Teach Instead

Global change is the result of millions of local actions. The 'Global Citizen Project' helps students see the direct link between their own choices and global outcomes.

Common Misconception

Sustainability is only about the environment.

What to Teach Instead

It also includes economic and social factors, like fair wages and equal access to education. Peer discussion of the 'Future World Summit' goals helps students see this broader definition of sustainability.

Active Learning Ideas

Inquiry Circle: The Global Citizen Project

Groups identify one global problem (e.g., plastic in the ocean or food waste) and research how it is being solved in different parts of the world. They must propose a 'local action' that their school or community could take to help.

60 min·Small Groups

Simulation Game: The Future World Summit

Students represent different regions of the world and must negotiate a 'Global Sustainability Goal' for the year 2050, balancing the needs of developed and developing nations.

50 min·Small Groups

Think-Pair-Share: My Geographic Footprint

Students reflect on where their food, clothes, and energy come from. They share with a partner one change they could make to their own habits to improve the geography of their local and global community.

Real-World Connections

• Scientists at McMurdo Station, the largest research base in Antarctica, conduct studies on glaciology, meteorology, and astronomy, contributing data used by climate modelers worldwide.
• The International Whaling Commission, though not solely Antarctic, has historically managed whale populations in the Southern Ocean, demonstrating international cooperation for environmental protection in the region.
• Coastal city planners in places like Miami, Florida, and Jakarta, Indonesia, use projections of sea-level rise, partly informed by Antarctic ice melt data, to develop adaptation strategies and infrastructure improvements.

Assessment Ideas

Quick Check

Present students with three statements about Antarctica: 1. It is governed by a single country. 2. It is a hub for international scientific research. 3. Its ice melt directly affects global sea levels. Ask students to label each statement as True or False and provide one piece of evidence from the lesson to support their answer for each.

Discussion Prompt

Pose the question: 'Imagine you are a diplomat attending a meeting of the Antarctic Treaty Consultative Parties. What is one scientific priority you would advocate for, and why is it crucial for global well-being?' Facilitate a brief class discussion where students share their ideas and justify their choices.

Exit Ticket

On an index card, have students write two reasons why Antarctica is unique among the continents and one potential global impact if its ice sheets continue to melt at an accelerated rate.

Frequently Asked Questions

What is a global citizen?

A global citizen is someone who understands the wider world, their place in it, and takes an active role in their community to work with others to make our planet more equal, fair, and sustainable.

What are the Sustainable Development Goals (SDGs)?

They are a collection of 17 interlinked global goals designed to be a 'blueprint to achieve a better and more sustainable future for all,' established by the United Nations in 2015.

How can technology help with sustainability?

Technology can provide clean energy (like solar and wind), improve food production (like vertical farming), and help us track and reduce our impact on the environment through data and GIS.

How can active learning help students prepare for the future?

Active learning strategies like 'The Global Citizen Project' turn students from passive learners into active problem-solvers. By having to research, design, and propose real-world solutions, they develop the critical thinking and collaboration skills they will need as the leaders of tomorrow. This approach makes geography not just a subject to study, but a tool for building a better world.
