IB Environmental Systems and Societies HL - Questionbank

Topic 4 All - Water

These new IB ESS Case Studies have been designed for you to apply your knowledge and understanding of Environmental Systems & Societies in challenging Paper 1-style contexts. Each Case Study provides you with a range of materials about a country or region and a set of questions of varying levels of difficulty. A complete markscheme identifies the ESS concepts and terminology required to achieve the marks and a sample answer allows you to see how this could be compiled into a good response. The Case Studies are organised into themes taken from the Environmental Systems and Societies HL concepts: three themes focusing on nature and four on humans. All the Case Studies are written in a Paper 1-style; our team of experienced IB ESS teachers and examiners have created both full-length and shorter examples as well as three levels of difficulty to suit a range of revision needs.

Original Paper 1-style case studies designed to enhance your skills in analysing data. With varying lengths, difficulty levels, and themes, you can select the ideal practice material for Paper 1 at any point in your ESS course.

Develop your understanding in IB ESS HL using custom-built flashcards, perfect for quick study sessions on desktop or mobile app.
