Urban Systems & Infrastructure
📋 What it is
A city is a giant system of connected networks — roads, water, power, food — all keeping it alive.
🗣️ Coach says
A city is one of the biggest human-made systems. It runs on interconnected NETWORKS: roads and transit (movement), pipes (water), wires (power), cables (data), and supply chains (food). Each depends on the others — a power cut can stop water pumps and traffic lights. Cities live or fail as whole systems.
🧠 Memory hook
City = connected networks (roads, water, power, data, food) that depend on each other. Live/fail as one system.

What did the cause say to the effect?
"I didn't mean to push your buttons — but it was a chain reaction!"
😲 Whoa!
A big city must have food constantly flowing in — most cities have only a few days’ worth of food at any moment, kept stocked by a vast, invisible supply-chain system.
✅ Quick check: Why can a single power cut cause many problems across a city?
Say your answer out loud first — then reveal.
City networks are interconnected — losing power can stop water pumps, traffic lights, and more, rippling outward.
Urban networks are interdependent systems.
