👩‍🏫 Teacher’s Guide

Objective
Read a geographic dataset, including its variables, units, and assumptions.

Vocabulary
network, capacity, bottleneck

Suggested time
30-40 minutes, with optional practice across the week.

Teaching Notes

• Ask students to identify units and assumptions before calculating. Require a written explanation that separates observations, calculations, and conclusions.
• Introduce the study resource before assigning questions. Students can answer using this lesson without opening the source book.
• Use questions 1-4 for guided practice and the remaining questions for independent practice or discussion. Open responses may use different wording if the evidence supports them.
• Check the activity against its stated constraints and the answer bank. Revisit a missed concept before adding a new one.

🧒 Student Worksheet

Concept and Helping Material

Places exchange goods because resources, production, and demand differ. A transport network consists of places connected by routes. Cost per shipment and capacity per day answer different questions. A closed connection can interrupt an entire route. The fictional routes below each connect Farm to Port by a different way. Begin by identifying the variables, units, and stated assumptions. Locate each fact before making comparisons.

Study Resource

Vocabulary and Definition

• - a set of places connected by routes
• - the maximum amount a system can handle in a stated period
• - a part of a network that limits total movement

Hands-On Experiment or Activities

What You Need: Paper, pencil, and a calculator for checking arithmetic.

What You Do:

1. Draw a three-route network between Farm and Port. Plan delivery of 25 shipments, then close one route and revise the plan.
2. Share your result. Ask a partner to check the evidence and challenge one assumption.
3. Revise one part of your work after checking it against the lesson evidence.

Think and Talk: What evidence supports one choice in your work?

Reflection

• Which idea can you explain now?
• What would you still need to learn about a real place?

Teacher Check

Check accurate use of the study resource, correct vocabulary or units, and a reason supported by evidence. For open activities, accept more than one result when it follows the instructions. The companion CSV contains the same numbered Q&A bank shown above.
