Unit 1: How are Earth’s dynamic systems interconnected to support life?
In this unit students examine the processes and interactions occurring within and between Earth’s four interrelated systems – the atmosphere, biosphere, hydrosphere, and lithosphere. They focus on how ecosystem functioning can influence many local, regional, and global environmental conditions such as plant productivity, soil fertility, water quality and air quality. Students explore how changes that have taken place throughout geological and recent history are fundamental to predicting the likely impact of future changes. They consider a variety of influencing factors in achieving a solutions-focused approach to responsible management of challenges related to natural and human-induced environmental change.
Unit 2: What affects Earth’s capacity to sustain life?
In this unit students consider pollution as well as food and water security as complex and systemic environmental challenges facing current and future generations. They examine the characteristics, impacts, assessment, and management of a range of pollutants that are emitted or discharged into Earth’s air, soil, water and biological systems, and explore factors that limit and enable the sustainable supply of adequate and affordable food and water.
