Part 1: The Hook and Mission Briefing (15 Minutes)

The Hook: The Global Lunchbox

Educator Prompt: Imagine you are packing a simple sandwich for lunch. The wheat for the bread came from Canada, the meat was processed by an American company but raised in Brazil, and the tomatoes were grown in Mexico. If there was a major storm in Canada that wiped out the wheat harvest, what would happen to your sandwich? What happens to the bakeries in America? This is the core of global interdependence.

Learning Objectives (Our Mission Goals)

By the end of this lesson, you will be able to:

1. Define and provide examples of global economic interdependence.
2. Map the journey of a product through a complex supply chain.
3. Identify the role of Transnational Corporations (TNCs) in connecting and controlling global supply chains.

Success Criteria

You know you have succeeded when you can:

• Accurately trace a common household item back to at least three different countries or regions.
• Explain what would happen to that product’s availability if a major economic disruption occurred in one of those three places.

Part 2: Defining the Players and the Chain (I Do) (20 Minutes)

I Do: The Core Concepts

1. Global Economic Interdependence

Definition: This simply means that countries rely on each other to produce and consume goods and services. No country can produce everything it needs efficiently.

• Why does it matter? Think of the global economy as a complex machine made of millions of gears. If one gear (a country or resource) breaks, the whole machine slows down or stops.
• Example: The US relies on China for cheap manufacturing; China relies on the US for a massive consumer market. They are dependent on each other for their economies to thrive.

2. The Supply Chain: From Dirt to Doorstep

The supply chain is the entire system of organizations, people, activities, information, and resources involved in moving a product or service from supplier to customer.

1. Raw Materials: Where does the basic stuff come from? (E.g., rubber from Malaysia, cotton from India, lithium from Chile).
2. Manufacturing/Processing: Where is the raw material turned into the final product? (Often countries with lower labor costs, like Vietnam, China, or Mexico).
3. Distribution/Logistics: How does it move? (Huge container ships, massive warehouses managed by companies like Amazon or FedEx).
4. Retail/Consumer: Where do you buy it? (Your local store or online shop).

3. Transnational Corporations (TNCs)

Definition: These are huge companies that operate and coordinate production across many countries. They are the directors of the global economic play.

• Example: Nike doesn't own cotton farms or shoe factories; they design the shoes in the US, contract factories in Vietnam, source rubber from Thailand, and sell them globally.
• TNC Impact: They often decide where jobs go, what prices are charged, and how fast products move, making them incredibly powerful global actors.

Formative Check-In (Quick Q&A)

Question for Heidi: If a TNC that manufactures smartphones decides to move its main factory from Thailand to Indonesia, what are the immediate economic effects in both Thailand and Indonesia?

(Expected Answer: Thailand loses jobs/economic activity; Indonesia gains jobs/economic activity. This shows interdependence and the power of TNCs.)

Part 3: Mapping the Supply Chain (We Do & You Do)

We Do: The Global Coffee Bean (Guided Practice) (20 Minutes)

Let’s trace a common product together: a cup of coffee.

1. Educator Modeling: I will start with a typical coffee company (like Starbucks, a TNC). Where do they get their beans? (Brazil, Colombia, Vietnam).
2. Step 1: Raw Materials: Coffee beans grown in Brazil. (Plot Brazil on the map).
3. Step 2: Processing: Beans are exported to Europe (maybe Germany or Italy) for roasting and packaging. (Plot Europe).
4. Step 3: Logistics: The roasted beans are shipped via container ship to the US port of Seattle.
5. Step 4: Retail: Sold to us in the local coffee shop.
6. Discussion: What if a drought hits Brazil? The entire global coffee supply chain is disrupted, proving interdependence.

You Do: Supply Chain Detective (Independent Application) (45 Minutes)

Now it is your turn to become a global detective. Choose the physical item you gathered earlier (T-shirt, phone charger, etc.).

Activity: The Global Journey Map

Instructions: Use the internet to find out where your chosen product came from. Look for:

1. The Company (TNC): Who owns the brand? Where is their headquarters located?
2. The Manufacturing Location: Look on the label (or charger sticker/box) for "Made in..." (This is usually the final assembly point).
3. Raw Materials Origin: This takes research. If it’s a T-shirt, where is most of the world's cotton grown? (Often China, India, US). If it's electronics, where do the metals come from?
4. Logistics Path: Trace the path from the manufacturing country to your location. Which oceans/continents did it cross?

Structured Output (Required for Success Criteria)

In your notebook, organize your findings for your chosen item:

• Product: _____________________
• TNC Headquarters: _____________________ (Country: _____)
• Manufacturing/Assembly Country: _____________________
• Raw Material Origin Country 1: _____________________
• Raw Material Origin Country 2: _____________________
• Interdependence Analysis: Describe a potential disaster (political strike, natural disaster, economic collapse) in one of your listed countries and explain how it would affect the final product getting to you.

Part 4: Conclusion, Recap, and Reflection (15 Minutes)

Learner Presentation (Summative Assessment)

Heidi will present her "Global Journey Map" to the educator/group, detailing the supply chain of her chosen product and explaining the interdependence analysis.

Key Takeaways Recap

Educator Prompt: In one or two sentences, explain the power of TNCs and why their decisions affect entire countries.

Summary Points:

• Interdependence means we are all economically linked like threads in a giant tapestry.
• The supply chain has many hidden steps managed by complex logistics.
• Transnational Corporations (TNCs) are the chief organizers of this global exchange, moving production and jobs wherever it is most profitable.

Next Steps and Reflection

Discussion Question: Knowing how dependent the world is on these long, complex supply chains, do you think it is a good idea for a country to rely on others for critical goods (like medicine or food)? Why or why not?

Differentiation and Adaptability

Scaffolding (For learners needing support)

• Product Choice: If research proves too difficult, provide a simple product with clearly marked origins, like an apple or a pencil.
• Guided Research: Provide specific search terms (e.g., "where is cotton grown," "largest rubber producers").
• Visual Aid: Require drawing a physical path on a printed world map rather than just listing countries.

Extension (For advanced learners)

• Cost Analysis: Research the estimated labor cost vs. raw material cost vs. retail price for their chosen item. What percentage of the final price goes to the TNC?
• Ethical Impact: Investigate the labor standards or environmental impact (e.g., carbon footprint) associated with the longest leg of their product’s journey. How does global interdependence complicate global responsibility?

Context Adaptability

• Homeschool/Individual: The "Supply Chain Detective" can be a deep research project culminating in a written report or video presentation.
• Classroom: Groups can investigate different products (e.g., Group A traces a phone, Group B traces a snack food) and then combine their findings to create a shared "Global Market Board" demonstrating collective interdependence.
• Training/Workplace: Focus the research on a specific company/industry (e.g., tracing a microchip used in IT equipment) and analyze the geo-political risks associated with reliance on single-source suppliers.
