Global Supply Chains and Production

Active learning works for this topic because students need to move beyond abstract ideas about global systems and see how digital connections shape real-world networks. Hands-on activities help students grasp the physical and human geography behind technology they use daily, making invisible infrastructures visible.

Activity 01

• Gallery Walk
• 40 min · Pairs

Gallery Walk: The Digital Divide

Display maps showing global internet speeds, smartphone ownership, and undersea cable networks. Students move in pairs to identify which regions are 'disconnected' and brainstorm the consequences for a student living there.

Analyze the complex stages involved in the global supply chain of a common product.

Facilitation Tip

During the Gallery Walk, position yourself near the digital divide maps and listen for students to notice patterns in access rather than just stating general facts.

What to look for

Provide students with a common product, like a t-shirt or a pair of sneakers. Ask them to list three distinct stages of its global supply chain and identify one potential ethical concern at each stage.

Activity 02

• Formal Debate
• 50 min · Whole Class

Formal Debate: Social Media and Place

Students debate whether social media makes us more connected to the world or if it creates a 'distorted' view of reality. They must use examples of how travel influencers or news trends shape our perception of distant countries.

Explain how geopolitical events can disrupt global supply chains.

Facilitation Tip

For the Structured Debate, assign roles clearly and remind students to ground arguments in evidence from their app-mapping work.

What to look for

Pose the question: 'If a major earthquake occurred in a key manufacturing region like Taiwan, how might this event impact the availability and price of electronics in Australia?' Facilitate a class discussion on the ripple effects through the supply chain.

Activity 03

• Inquiry Circle
• 45 min · Small Groups

Inquiry Circle: App Mapping

In small groups, students trace the 'geography' of a popular app (e.g., TikTok or Instagram). Where is the company based? Where are the servers? Where are the most users? They present their findings as a digital map.

Evaluate the ethical implications of global production practices on labor and environment.

Facilitation Tip

When students complete the App Mapping activity, circulate to ask probing questions like, 'What surprised you about the data costs in different countries?' to deepen their analysis.

What to look for

Show a short video clip depicting a specific stage of a supply chain (e.g., a coffee plantation, a shipping port, a factory). Ask students to write down the product being handled, the location shown, and one challenge faced at that stage.

A few notes on teaching this unit

Experienced teachers approach this topic by grounding abstract concepts in tangible examples. Begin with a product students know well, like a smartphone or sneaker, and unpack its journey step-by-step. Avoid simply lecturing about global networks; instead, use jigsaw discussions so students teach each other about different parts of the supply chain. Research suggests that students retain more when they physically map connections and debate real-world trade-offs.

Students will recognize that digital connections depend on physical infrastructure and human decisions. They will analyze how technology links places and people, and explain why access is uneven across the globe. Discussions and mapping tasks will show their growing ability to connect concepts to real-world examples.

Watch Out for These Misconceptions

• During Gallery Walk: The Digital Divide, students may think the internet is everywhere and ignore evidence showing gaps in access.

  During the Gallery Walk, point students to the undersea cable maps and data about rural internet speeds. Ask them to compare urban and rural areas and explain why access differs.

• During Collaborative Investigation: App Mapping, students may assume that all apps work the same way globally.

  During the App Mapping activity, ask students to compare app performance and data costs across countries. Use this to highlight how infrastructure and policy shape digital experiences.
