OCR A Level Geography Exploring Oceans: CLIMATE CHANGE IS CHANGING THE OCEANS

Designed specifically for OCR A Level Geography, this engaging, fully resourced lesson explores how climate change is transforming the ocean system through a combination of clear teaching, retrieval, enquiry and exam-focused application. Students investigate ocean acidification, coral bleaching, sea-level rise and declining Arctic sea ice, applying their understanding to memorable named examples including the Great Barrier Reef, the Maldives and the Arctic. Interactive activities include process sequencing, impact chains, ecosystem-service classification, the Arctic albedo feedback loop, stakeholder challenges, concept mapping and evaluative decision-making, helping students connect physical processes to their environmental, social, economic and geopolitical consequences. The lesson builds towards higher-level OCR geographical thinking, requiring students to compare vulnerability, use place-specific evidence and reach supported judgements. A dedicated student worksheet/revision resource is included, making this suitable as both a complete taught lesson and a valuable revision resource.
