AP Environmental Science course aim is to nurture students with scientific principles, concepts, and methodologies that are required to understand the interrelationships of the natural world, to analyse and evaluate environmental problems i.e.natural and human-made, to evaluate the risks associated with these problems and to find the various alternative solutions for resolving them and for the preservation.

Environmental science is interdisciplinary; it focuses on different variety of topics from different areas of study, Still there are several major unifying constructs and themes, that includes many topics being included in the study of environmental science. Following themes that are given below, will provide a basic foundation for the structure of the AP Environmental Science course.

  • Science is a process.
  • Science is a process of learning more about the world.
  • Science frequently changes the way we understand the world, hence it is dynamic and not static.
  • Energy conversions underlie all ecological processes.
  • The Energy cannot be created or formed; it must come from somewhere.
  • As energy flows through systems, at each step more of it becomes unusable.
  • The Earth is one interconnected system.
  • Natural systems change over time and space.
  • Biogeochemical systems differ in ability to recover from disturbances.
  • Humans alter the natural systems.
  • Humans have had an impact on the environment for millions of years.
  • Technology and population growth have enabled humans to increase their rate and scale on the environment.
  • Environmental problems have both cultural and social context.
  • Understanding the role of cultural, social and economic factors is vital to the development of solutions.
  • Human survival depends on developing practices that will achieve sustainable systems.
  • A rational combination of conservation and development is required.
  • Common resources and their management is essential.

The following course will focus on the topics quoted below:
