Activities & model answers

Activity 1 — Components of infrastructure

Key
Hard (economic): motorway, shipping port, electricity grid, mobile network, water treatment plant. Soft (social): public hospital, high school, emergency services. Accept sensible additions (e.g. hard: airport/gas pipeline; soft: library/aged-care).

Activity 2 — Compare US vs China

Key
USA: challenge = ageing/renewal & maintenance backlog; example = bridges/roads/water mains; source = ASCE Infrastructure Report Card ("C-" range, 2021); risk = safety, funding gap. China: challenge = rapid new-build expansion; example = Belt and Road Initiative + world's largest high-speed rail network; risk = environmental impact, debt sustainability for partners. Sentence: a mature economy must renew an existing network; a fast-growing economy must build new capacity at speed.

Activity 3 — Two metros

Key
Shanghai: one of the world's longest metro systems, opened 1993, built for rapid urbanisation. Sydney: Australia's first fully automated (driverless) metro, North West line opened 2019, extended under the harbour/CBD. Interchange: a station where two or more lines meet, letting passengers transfer between routes — it multiplies the journeys the network can serve without new track, making the whole system far more useful (network effect).

Activity 4 — Evaluate sustainable infrastructure

Model
Agrees that sustainability matters (Sydney Metro's automation/high frequency shifts trips off roads; smart/automated ports cut emissions and waste through efficiency and renewable energy). A strong answer also weighs the other side — size/capacity still matters where demand is growing — and concludes that the best infrastructure integrates both scale and sustainability/resilience.

Activity 5 — Key concepts

Indicative
Interconnection = networks physically link places & people to services; Scale = infrastructure runs local (a metro line) to global (Belt and Road corridors); Change = industrial-age build → digital-age smart systems, and ageing → renewal; Sustainability = green materials, clean energy, resilience, reducing emissions.

Key questioning (with answers)

Differentiation

  • Support: pre-sorted word bank for Activity 1; sentence starters for the evaluation.
  • Extension: research a third example (e.g. a specific BRI port, or a smart port such as Rotterdam) and evaluate its sustainability; critique the reliability of BRI/HSR figures.
  • EAL/D: visual glossary (infrastructure, hard/soft, network, interchange, automated, sustainability).

Assessment & homework

  • Exit ticket: one component of infrastructure + one difference between ageing and expanding patterns.
  • Homework: the Activity 4 evaluation, written up; read 7.4 (Patterns of Economic Activity).

Useful resources

Teaching note — verify the numbers. BRI spending totals and high-speed-rail route lengths are frequently revised and politically contested; teach them with relative language ("one of the largest", "the world's largest HSR network") and attribute any specific figure. The ASCE grade cited is the 2021 Report Card ("C-" range) — check for a newer edition before quoting. Figures on the study page are illustrative schematics — use official network maps (Sydney Metro / Shanghai Metro) for real detail.

🎦 Teaching-presentation — answer & discussion guide

Model points for the reflection, research & essay tasks in 7.3 Infrastructure's teaching deck (_teaching.html). Not exhaustive — students should reason & use evidence.

Reflect — is big infrastructure the best use of public money?
Research — Sydney Metro

Look for: correct open/building/planned lines; a real benefit (travel time, capacity) + criticism (cost, disruption); housing/urban-shape effects near stations.

Essay — infrastructure pattern & change

Reward: the ageing-vs-expanding contrast; a case study (Shanghai/Sydney); effects on economy & where people live; interconnection + change.
