Week 14: Solving Problems Across Borders
When the Whole World Needs to Work Together
Some problems don't care about borders.
Air pollution from one country drifts into another. A disease outbreak in one region can reach every continent within weeks. Ocean plastic from one coast washes up on another.
These are global challenges — problems so big that no single country can solve them alone.
This week, you'll explore why these problems require cooperation, how the world organizes to address them, and what role ordinary citizens play in global solutions.
The big idea:
Some problems are getting worse every year and no single country can stop them alone. Pollution, disease, poverty, and conflict cross every border — and they will keep growing unless countries work together to address them.
- You do not need to teach every bullet on the page. Use the learning goal and one or two activities for the session you are teaching today.
- If time is short, teach one guided session well and leave the rest for later. The lessons are designed to stretch across the week.
- The independent session works best after the learner has already explored the main idea with you once.
Teacher Preparation
- Choose 2-3 global challenges to discuss (climate change, ocean pollution, pandemic preparedness, clean water access, refugee protection).
- Bookmark the United Nations Sustainable Development Goals for Kids page.
- Prepare a world map (physical or digital).
- Prepare materials for the Global Challenge Team activity.
- Prepare a visual timer for sessions.
Global problems can feel overwhelming. The goal is not to make the student anxious — it's to show them that cooperation works and that solutions exist. Focus on stories of progress alongside the challenges.
Guided Session 1
Problems Without Borders
Learning Goal
By the end of this session, the student can:
- identify global challenges that require international cooperation
- analyze why these problems cannot be solved by a single country
- compare global cooperation to the community cooperation studied earlier in the course
Activities
1. The Border Test (8 minutes)
Ask:
"Does pollution stop at a country's border? Does a virus check your passport before it infects you?"
The answer is no. Some problems are inherently borderless.
Brainstorm a list together:
| Global Challenge | Why It Crosses Borders |
|---|---|
| Air pollution / climate change | Air moves everywhere; emissions from one country warm the whole planet |
| Ocean plastic | Currents carry trash across oceans |
| Pandemics | Travelers carry diseases between countries |
| Refugees | People flee one country to find safety in another |
| Overfishing | Fish swim across borders; one country's overfishing affects everyone |
| Cybersecurity | The internet connects every country |
"None of these problems can be solved by one country acting alone. They all require teamwork."
2. The Flashback (5 minutes)
Connect this to what the student already knows:
"Remember Week 2 — the Island Challenge? When everyone on the island only looked out for themselves, things fell apart. The same is true for countries. The same cooperation skills you've been learning all semester apply at the global level too."
You can also reference the Social Contract (Week 4) and how local government pools resources through taxes (Weeks 10–11) — these parallels reinforce that the cooperation principles students have learned scale all the way from neighborhoods to the entire planet.
3. Examples of Global Cooperation Working (10 minutes)
Share real examples of progress:
The ozone layer: In 1987, countries signed the Montreal Protocol to ban chemicals that were destroying the ozone layer. It worked — the ozone layer is healing.
Smallpox: Through a coordinated global vaccination campaign led by the WHO, smallpox was completely eradicated in 1980. It's the only human disease ever wiped out.
The International Space Station: 15 countries worked together to build a laboratory in space. Astronauts from different nations live and work there together.
"These examples prove that when countries cooperate, they can solve problems that seemed impossible."
Reflection Questions
- "Why is it harder to solve a global problem than a local one?"
- "Which global challenge do you think is the most urgent right now? Why?"
- "What would you say to someone who says 'my country should just worry about itself'?"
Guided Session 2
Building Global Solutions
Learning Goal
By the end of this session, the student can:
- evaluate different approaches to solving a global problem
- design a basic international cooperation plan
- justify why compromise and shared sacrifice are necessary for global solutions
Activities
1. The United Nations Sustainable Development Goals (10 minutes)
Introduce the SDGs:
"In 2015, all 193 countries in the United Nations agreed on 17 goals to make the world better by 2030. These are called the Sustainable Development Goals."
Share a few:
| Goal | What It Means |
|---|---|
| No Poverty | End extreme poverty everywhere |
| Zero Hunger | Make sure everyone has enough food |
| Quality Education | Give every child access to school |
| Clean Water | Provide clean water and sanitation for all |
| Climate Action | Take urgent action to fight climate change |
| Life Below Water | Protect the oceans |
| Peace and Justice | Build fair institutions and promote peace |
"These are goals that every country agreed to work toward together. No one country can achieve them alone."
Ask:
"Which goal do you think is the most important? Which one surprises you?"

2. Global Challenge Team (12 minutes)
Pick one global challenge and design a basic cooperation plan.
Choose a challenge: (or let the student pick)
- Ocean plastic pollution
- Access to clean drinking water
- Protecting endangered animals
Work through these questions together:
- What is the problem? (Describe it clearly)
- Why can't one country solve it alone? (What makes it global?)
- What would countries need to agree on? (Rules, funding, targets)
- Who would lead the effort? (An existing organization? A new one?)
- What would each country need to do? (Reduce plastic? Share water technology? Create protected areas?)
- How would you know if it's working? (How would you measure progress?)
Write up the plan on a single sheet. This is what international negotiators actually do — just with more detail and many more people.
3. The Free Rider Problem (8 minutes)
Present a tricky concept:
"What if 190 countries agree to reduce pollution, but 3 countries refuse? Those 3 countries benefit from everyone else's efforts without doing any of the work. This is called the free rider problem."
Connect it to the island:
"Remember the island community? What if one person on your island refused to follow the rules but still benefited from the safety, shared food, and clean water that everyone else worked to maintain? That's a free rider — and it's just as frustrating at the global scale."
Ask:
"Is this fair? What should the other countries do?"
Discuss options:
- Apply pressure through diplomacy
- Impose trade sanctions
- Offer help (maybe those countries lack resources to participate)
- Lead by example and hope they follow
"There's no perfect answer. This is one of the hardest challenges in international cooperation."
Reflection Questions
- "Why is it important that every country participate in solving global problems, not just rich or powerful countries?"
- "What happens if countries agree to a goal but don't actually follow through?"
- "How can ordinary citizens — even kids — contribute to solving global challenges?"
Independent Session
Propose a Global Solution
Instruction
Pick a global challenge and write a one-page proposal for how the world should solve it.
Choose from this list (or pick your own):
- Reducing ocean plastic pollution
- Making sure every child in the world can go to school
- Protecting an endangered species
- Preparing for the next pandemic
- Providing clean drinking water to everyone
Your proposal should answer:
- What is the problem? (2-3 sentences)
- Why does it require international cooperation? (Why can't one country fix it alone?)
- What is your proposed solution? (Be specific — who does what?)
- What would countries need to agree to? (What are the rules?)
- How would you measure success? (How do you know if it's working?)
- What's the biggest obstacle? (What might prevent countries from cooperating?)
- Your closing argument: Why should the world prioritize this?
Write clearly and persuasively. Imagine you are presenting this proposal to the United Nations General Assembly.
Connection to the final project: In Weeks 15-18, you'll do something similar — but for your own community. Think of this as practice.
Skills Reinforced
- identifying global challenges that cross national borders
- analyzing why international cooperation is necessary
- designing structured solutions with clear roles and accountability
- persuasive communication about complex issues
Setup
- computer or paper for writing
- access to the internet for research
- the Sustainable Development Goals list (link above)
- visual timer
- United Nations (UN) — An international organization where nearly every country in the world is a member. It was created to promote peace, cooperation, and human rights.
- Climate change — Long-term shifts in temperatures and weather patterns around the world, largely caused by burning fossil fuels. It's a global problem because emissions from any country affect the whole planet.
- Sustainable development — Meeting the needs of people today without ruining things for future generations. The UN's Sustainable Development Goals are a plan for doing this.
- Border — The official line between two countries. Some problems — like pollution, disease, and climate change — don't stop at borders.
- Cooperation — Working together toward a shared goal. International cooperation means countries agreeing to act together on problems that affect everyone.
- Global — Something that involves or affects the whole world, not just one country or region.
Some problems are so big that no single country can fix them alone — things like pollution, disease, and climate change don't stop at borders. That's why countries work together through organizations like the United Nations. When countries cooperate, amazing things can happen — like healing the ozone layer and wiping out diseases. You can be part of the solution too, even as a kid!
Check for Understanding
- Name two global challenges that cannot be solved by one country acting alone. Why not?
- What are the Sustainable Development Goals, and why did countries agree to them?
- What is the "free rider problem" in international cooperation? Why is it such a challenge?
- How can ordinary citizens — including kids — contribute to solving global problems?
Core vs. Stretch
- Core: Identify global challenges that cross borders, explain why international cooperation is necessary, and discuss the Sustainable Development Goals. Complete the Global Challenge Team activity.
- Stretch: Write a full one-page proposal for a global solution (independent session), research a specific international agreement (like the Montreal Protocol), or connect a global issue to something happening in your own community.
Adapting for Different Ages
- Focus on one or two global challenges that are easiest to visualize: ocean plastic and clean water work well because kids can picture them.
- For the SDGs, pick just 3–4 goals and ask which one they think is most important. Don't try to cover all 17.
- Keep the Global Challenge Team activity short: pick one problem and answer just the first three questions (What is it? Why can't one country fix it? What would countries need to agree on?).
- Skip the free rider concept, or introduce it very simply through the island analogy: "What if one islander refused to help clean up but still used the clean beach?"
- Cover the full Global Challenge Team activity with all six questions, and challenge the learner to propose specific, measurable targets ("reduce ocean plastic by 50% in 10 years" rather than "reduce plastic").
- Dive deeper into the free rider problem and discuss real-world parallels: "Why might a country choose not to sign a climate agreement?"
- For the independent session, push toward the full one-page proposal and require at least one cited source.
- Ask: "The Montreal Protocol worked — the ozone layer is healing. Why do you think climate change has been harder to solve than the ozone problem?"
Discussion Norms for This Week
Global problems can trigger strong feelings — especially climate change, poverty, and conflict. Before starting:
- Hope and honesty together. It's OK to say "this is a serious problem" AND "people are making progress." Both can be true.
- Stick to what we can learn. Focus on understanding systems and cooperation, not on assigning blame to specific countries.
- Feelings are data too. If a topic makes you worried or angry, that's worth noticing — but channel it into "What could people do about this?" rather than despair.
- "I don't know" is fine. These are problems that experts spend careers on. Not having all the answers is honest.
🔍 Civic Inquiry Spotlight: Does Cooperation Actually Work?
You might hear someone say: "International agreements never work — countries just ignore them."
Let's check that claim:
| Claim | What Actually Happened |
|---|---|
| "The ozone treaty didn't work" | The Montreal Protocol (1987) was signed by 197 countries. The ozone hole is measurably shrinking. Scientists expect full recovery by ~2066. |
| "Countries never cooperate on disease" | The World Health Organization coordinated the eradication of smallpox (1980) — a disease that killed ~300 million people in the 20th century alone. |
| "Nobody follows climate agreements" | Mixed — some countries exceeded targets, some fell short. The Paris Agreement (2015) created a framework, but enforcement is voluntary. Progress is real but uneven. |
The takeaway: International cooperation doesn't always work perfectly — but the claim that it never works is not supported by evidence. The harder question is: Under what conditions does cooperation succeed, and what makes it fail?
Try this: When you hear a big claim about whether global cooperation works or doesn't, ask:
- Which agreement? (Get specific)
- What was the goal, and what actually happened? (Check the evidence)
- Is the person comparing it to perfection — or to what would have happened without the agreement?
Offline Option
If internet access is not available, the facilitator can verbally describe 3-4 of the UN Sustainable Development Goals (No Poverty, Clean Water, Climate Action, Quality Education) and have the learner discuss or write about them. Print the SDG list ahead of time if possible, or simply describe the goals in conversation. The Global Challenge Team activity and the free rider discussion are already fully hands-on and need no technology. For the independent session, the learner can write their global solution proposal on paper based on what they learned during the guided sessions.
Local Adaptation Note
Global issues might feel far away, but they connect to your community in real ways.
- "Are there any global issues that affect your local area — weather, trade, pollution?"
- Climate change shows up locally as changing weather patterns, stronger storms, droughts, or flooding. Ask the learner if they've noticed any changes.
- If your community relies on imports (food, fuel, manufactured goods), talk about how international trade affects local prices and availability.
- Look for local organizations or school programs that work on global issues — recycling programs, food drives for international aid, or cultural exchange events.
- Global issues can feel overwhelming. Balance urgency with agency. Progress is real (ozone recovery, smallpox eradication, the ISS). Focus on what people CAN do.
- Avoid doom and gloom. Build informed citizens, not anxious ones. If a learner seems worried, redirect: "What's one thing you could do about that?"
- The free rider problem can frustrate kids with a strong sense of fairness. Use that energy — ask them to brainstorm solutions, just like international negotiators do.
- This wraps up Unit 4. Look back at the arc: local government (Weeks 10–12) to the global stage (Weeks 13–14). The same cooperation principles scale from neighborhoods to the planet.
