Overview

This hub brings together study notes for TASC Environmental Science Level 3, the Tasmanian pre-tertiary (Year 12) course in which learners develop investigative, analytical and communication skills and apply them to ecology and contemporary environmental issues. The course explores the nature of ecological systems, how human societies depend on and impact ecosystems, how ecosystems change both naturally and through human activity, and the principles used to manage environments sustainably.

The notes are organised into four modules that follow the structure of the course:

  • Ecological Processes covers ecosystem structure, biodiversity, energy flow, nutrient cycling and population and community dynamics.
  • Human Dependence and Impact on Ecosystems covers ecosystem services, resource use, pollution and waste management.
  • Local and Global Changes to Ecosystems covers climate change and the enhanced greenhouse effect, and biodiversity loss and introduced species.
  • Principles for Ecologically Sustainable Management covers sustainability and conservation strategies, and environmental monitoring and fieldwork.

Throughout, the notes use real Tasmanian and Australian examples so you can support your answers with specific, credible evidence.

Assessment

Environmental Science is assessed through a combination of internal school-based assessment and an external TASC examination, and a satisfactory result contributes to the Tasmanian Certificate of Education and the ATAR.

Internal assessment is conducted by your school across the course. It includes practical investigations in which you document a hypothesis, method, results and conclusions, and critically evaluate sources of error and the limitations of your design. A mandatory extended Case Study requires you to apply course knowledge to data you have collected yourself. Internal assessment covers criteria spanning scientific skills, knowledge of ecosystems, and understanding of the relationship between ecosystems and human society.

External assessment is set and supervised by TASC. Designated criteria are assessed in the external examination, and these ratings are combined with your internal ratings to determine the final award. Some criteria are assessed both internally and externally.

Please confirm the exact criteria, the number of internal and external ratings, and their weightings against the current TASC course document, because these details are updated when the course is re-accredited.

Common questions about Environmental Science

Is TASC Environmental Science Level 3 an ATAR subject?
Yes. Environmental Science is a TASC accredited Level 3 pre-tertiary course worth 15 credit points, and a satisfactory result can contribute to your Tasmanian Certificate of Education and your ATAR. Please confirm current credit points and rules on the TASC website, as accreditation periods are updated over time.
How is the course assessed?
The course uses both internal school-based assessment and an external TASC examination. The final award is determined from a set of ratings, with most coming from internal assessment and the remainder from external assessment, and several criteria are assessed both internally and externally. Confirm the exact number and weighting of criteria on the current TASC course document.
What is the mandatory Case Study?
The course includes a mandatory extended Case Study in which you apply course knowledge to data you have collected yourself. You document a hypothesis, method, results and conclusions, and critically evaluate sources of error and the limitations of your design. It is central to the practical investigation criteria.
What are the main topics in the course?
The course is built around the nature of ecological systems, how we depend on and impact ecosystems, how ecosystems change locally and globally, and the principles of ecologically sustainable management. These map to our four study modules on this hub.
What Tasmanian examples should I know?
Strong local examples include giant kelp forest collapse and the long-spined sea urchin, Devil Facial Tumour Disease, the strengthening East Australian Current, the Tasmanian Wilderness World Heritage Area, and salmon aquaculture. Using specific local cases lifts the quality of your answers.
How should I prepare for the external examination?
Practise explaining mechanisms clearly, distinguishing easily confused terms, and evaluating management strategies rather than just describing them. Learn a small set of detailed Tasmanian examples you can adapt to many questions, and rehearse interpreting data, food webs and graphs under timed conditions.
