This lesson helps students understand why development is uneven across the world. Through map analysis, case‑study snapshots and guided discussion, pupils explore the key physical and human factors that influence how quickly countries develop. They learn to link climate, resources, conflict, education and healthcare to real‑world development patterns, building the foundations for deeper geographical explanation.

By the end of this lesson, students will be able to:

Identify key factors that affect development

Explain how physical factors (climate, resources) influence development

Explain how human factors (education, healthcare, conflict) influence development

Analyse why development varies between countries

This ready‑to‑teach PPT and worksheet set strengthens geographical reasoning, supports comparative thinking and prepares students for later lessons on inequality and development strategies.
