ENSC 200 is not available for challenge.
ENSC 200 is a junior-level three-credit science course that provides an introduction to the basic scientific principles students need in order to understand environmental processes. It introduces students to the physical, chemical and biological components of the environment and uses a systems approach to provide an understanding of the interconnections of environmental systems. Data from a range of science disciplines are used to gain an understanding of the cycles that are vital to sustaining the earth’s ecosystems. The course also provides students with an understanding of causes, effects, and controls of a selection of environmental problems. Specific environmental problems are examined in order to illustrate the scientific approach to such problems. The course provides students with basic techniques and terminology to examine scientific issues with respect to the environment.

To receive credit for ENSC 200, you must achieve a course composite grade of at least “D” (50 percent), and a grade of at least 50 percent on the final examination. The weighting of the composite grade is as follows:
|Journal Article Evaluation||10%|
The final examination for this course must be taken online with an AU-approved exam invigilator at an approved invigilation centre. It is your responsibility to ensure your chosen invigilation centre can accommodate online exams. For a list of invigilators who can accommodate online exams, visit the Exam Invigilation Network.
