KS3 Geography — Human Impacts on Earth's Systems — Extension Pack

🌎 Stretch high achievers further with four ready-to-use enrichment activities on human impacts on Earth's systems — no preparation required. Earth has four interconnected physical systems — the atmosphere, hydrosphere, geosphere, and biosphere — and human activity, particularly population growth and industrialisation, has placed all four under significant pressure, and these tasks push students to apply that thinking, for KS3 students aged 11–14.

📦 What's included:

Vocabulary Matching (15 terms) — covering all key geographical terms from atmosphere to ecosystem

Challenge Quiz (25 marks) — harder multiple choice and true/false questions, a short answer on interconnected systems, and a data interpretation task using tropical land-use change data

Aral Sea Case Study (20 marks) — how river diversion and over-extraction of the hydrosphere triggered consequences across all four physical systems

Teach It Back task — students write an explanatory guide for a younger audience, assessed with a five-criterion rubric

Full answer keys and marking guidance included for all four activities.
