Lesson: Global Ripples & Interdependence
Duration
45 MIN
Learning Objectives
Identify the components of a global supply chain for everyday products.
Analyze how a localized natural disaster (tectonic events) can disrupt global trade.
Define and explain the concept of economic interdependence.
Key Vocabulary
Supply Chain: The network of people and companies involved in creating and distributing a product.
Interdependence: Mutual reliance between countries for goods, resources, and services.
Disruption: An event that interrupts the normal progress or activity of a process.
Ripple Effect: A situation where one event causes a series of other events to happen elsewhere.

Lesson Procedure
0-5 min
Warm-up: The Classroom Treasure Hunt
Ask students to find 3 items in the room (or on their person) and check the "Made In" labels. Have them list these on their worksheet. Discuss: Why don't we make everything right here in our town?
5-15 min
Video Analysis: Economic Impact
Watch the video segment from 8:30 to 9:17 . This section specifically discusses global supply chains and port damage. Use Slide 4 to facilitate note-taking on the worksheet regarding price increases and shortages.
15-40 min
Activity: Supply Chain Detectives
Group students (3-4). Distribute one Product Blueprint and one Disaster Scenario Card per group.
Students map the supply chain on their worksheet.
They must identify where the "break" in the chain occurs based on their scenario card.
They must brainstorm two specific consequences for a consumer in a different country.
40-45 min
Closure: The Interdependence Debrief
Lead a discussion using Slide 7. Ask: "If you could choose to make your country 100% independent (no imports), would you? Why or why not?" Connect back to the fertile soil and ocean resources mentioned in the video (5:19-6:02).
Teaching Tips & Differentiation
Differentiation
Scaffolding:
For students needing extra support, provide the "Smartphone" blueprint as it has the most clearly defined components. Pre-highlight the location on a world map.
Extension:
Challenge fast-finishers to research a "social ripple effect" from the video (9:18-9:41), such as how migration or refugees might impact a supply chain long-term.
Pro-Tips
Visual Aid:
Project a large Google Earth map during the activity so groups can "fly" to the locations listed on their blueprint cards.
The "Why":
Emphasize the video quote at 08:30: "Natural disasters in one part of the world can have global impacts." This is the core takeaway.
Expected Connections (Cheat Sheet)
Smartphone + Taiwan EQ
Disruption: Microchips. Effect: Phone prices skyrocket in USA; new releases delayed 6+ months.
Sneaker + Indonesia Tsunami
Disruption: Manufacturing & Ports. Effect: Major shortages in shoe stores; specialized athletic gear unavailable.
Chocolate + Brazil Flood
Disruption: Sugar harvest. Effect: Candy bar sizes might shrink ("shrinkflation") or prices increase at gas stations.

Connection: Land to Lab
Tectonic Event
An earthquake or tsunami occurs due to plate movement.
Economic Ripple
Ports are damaged. Factories shut down. Trade stops.
"Natural disasters in one part of the world can have global impacts."

1. What happened to the ports and bridges?
2. How did this affect the price of goods?
Key Concepts
Supply Chain
The complex network of people, companies, and transportation needed to get a product from raw materials to the consumer.
Interdependence
When countries rely on each other for resources and goods. If one country struggles, others feel the effect.
Supply Chain Detective

Map the broken link in the chain.
4
Predict the Ripple Effect.
Case Goal:
"Explain exactly how a natural disaster thousands of miles away changes your life today."
Final Thought
"If you could choose to make your country 100% independent (no imports), would you? Why or why not?"

Disaster Scenario:
Investigation Step 1: Map the Chain
Look at your Blueprint. Write down the 5 main stops for your product.
RAW MATERIALS
PARTS / COMPONENTS
ASSEMBLY / FACTORY
SHIPPING / PORT
RETAIL / CONSUMER
Investigation Step 2: Identify the "Break"
Based on your Scenario Card, which link in the chain above is broken? Explain why.
Investigation Step 3: Predict the Ripple Effect
If this chain breaks, how does it affect a teenager in a different country (like the USA)? List two specific effects.
