Course description

This college preparatory IB science studies environmental systems and societies (ES&S). Students will be provided with a coherent perspective of the interrelationships between environmental systems and societies; one that enables them to adopt an informed personal response to the wide range of pressing environmental issues that they will inevitably come to face.

The teaching approach is such that students are allowed to evaluate the scientific; ethical and socio-political aspects of issues.

Students will be able to study this course successfully with no specific previous knowledge of science or geography. However; as the course aims to foster an international perspective; awareness of local and global environmental concerns and an understanding of the scientific methods; a course that shares these aims would be good preparation.

During the course; students will study eight different topics. An important aspect of the ES&S course is hands-on work in the laboratory and/or out in the field.
