VCE Environmental Science study guide
VCE Environmental Science · Work through your exam, one topic at a time.
VCE Environmental Science is a Victorian Certificate of Education study accredited by the Victorian Curriculum and Assessment Authority for an accreditation period beginning in 2022. It is designed for senior secondary students in Victoria who want to understand how natural and human systems interact, and it runs across Units 1 to 4. The study design, updated in February 2022, sets out the areas of study, outcomes and assessment requirements for all four units. Assessment differs by unit: Units 1 and 2 use school-based assessment, while Units 3 and 4 include external assessment, supported by published examination specifications, past examinations and reports. The VCE Environmental Science study guide has 4 sections and about 1,124 words.
01Unit 1: How Are Ecosystems Connected?
Unit 1 examines ecosystems as systems of interacting components driven by energy flow and nutrient cycling. You must be able to distinguish biotic (living) from abiotic (non-living) factors, describe producers, consumers, decomposers and detritivores , and construct and interpret food chains, food webs and trophic levels .
327 words, about 2 min02Unit 2: How Does the Earth Support Life?
Unit 2 focuses on Earth's spheres and the processes that make the planet habitable. You must understand the atmosphere (composition, layers, greenhouse effect), hydrosphere (water cycle, ocean currents, salinity), lithosphere (rock types, soil formation, plate tectonics) and biosphere , and how they interact.
284 words, about 1 min03Unit 3: How Do Ecological Systems Change?
Unit 3 investigates change in ecosystems over time and in response to disturbance. You must understand succession (primary and secondary), climax communities , resilience and resistance , and population dynamics including exponential and logistic growth, carrying capacity, and factors affecting population size (density-dependent and density-independent).
255 words, about 1 min04Unit 4: How Can We Live Sustainably?
Unit 4 applies ecological understanding to human use of resources and sustainability. You must understand renewable and non-renewable resources , energy sources and their environmental impacts, waste management (reduce, reuse, recycle, recovery, disposal), pollution (air, water, soil, including eutrophication and acid deposition), and sustainable development .
