SACE Stage 2 Earth and Environmental Science study plan
SACE Stage 2 Earth and Environmental Science · Give each week a clear focus.
8 weeks · About 6 hours per week
Earth systems and their interactions & Inquiry skills: investigations, data analysis, and evaluation of conclusions
Construct a labelled systems diagram showing flows of energy and matter between the geosphere, atmosphere, hydrosphere and biosphere, and annotate at least six feedback loops as positive or negative
Distinguish between open, closed and isolated systems and classify four Earth subsystems using evidence from the diagram
Explain how a change in one sphere propagates to at least two others, using two worked examples with cause-and-effect chains of three or more steps
Identify the independent, dependent and controlled variables in three short described investigations, and state one improvement to each design
Your checkpoint
A one-page annotated systems diagram plus a 300-word written explanation of two cross-sphere feedback examples, self-marked against a checklist of the six required diagram features
Earth systems and their interactions & Inquiry skills: investigations, data analysis, and evaluation of conclusions
Describe the rock cycle and the carbon cycle, naming at least two reservoirs and two fluxes for each with approximate relative sizes
Interpret a provided table of carbon reservoir sizes and calculate the percentage of carbon held in each reservoir
Explain how plate tectonic processes link the geosphere to the atmosphere and hydrosphere over geological timescales
Evaluate a simple hypothesis about a sphere interaction by stating what data would confirm or refute it
Your checkpoint
A completed carbon-cycle data worksheet with percentage calculations shown and a 150-word evaluation of one hypothesis, checked against the worked answers
Earth's resources & Earth systems and their interactions
Classify at least eight Earth resources as renewable or non-renewable and justify each classification with a criterion
Describe the formation processes of three energy resources (for example coal, natural gas and geothermal) and link each to a sphere interaction
Compare the formation timescale of a fossil fuel with its consumption timescale and express the ratio as an order of magnitude
Construct a table comparing three energy resources on availability, extraction impact and greenhouse gas emissions per unit of energy
Your checkpoint
A resource comparison table covering three energy resources and eight classified resources, with a 200-word justification of the renewable/non-renewable boundary cases
Earth's resources & Inquiry skills: investigations, data analysis, and evaluation of conclusions
Interpret graphs of global or national resource production and consumption and describe two trends with supporting numerical evidence
Calculate a simple reserve-to-production ratio and explain two limitations of that indicator
Evaluate the environmental impacts of one extraction method using at least three criteria and a weighted decision matrix
Identify two sources of uncertainty in resource data and explain how each would affect a conclusion
Your checkpoint
A 400-word resource case study with an embedded graph interpretation, a reserve-to-production calculation, and a weighted decision matrix ranking two extraction options
Climate change & Earth systems and their interactions
Distinguish between the greenhouse effect, enhanced greenhouse effect and global warming, and explain each in terms of energy balance
Identify at least four natural and four anthropogenic drivers of climate change and rank them by estimated contribution with justification
Interpret a temperature anomaly graph and describe the trend, variability and a chosen baseline period
Explain two climate feedbacks (for example ice-albedo and water vapour) and state the direction of each
Your checkpoint
A 350-word annotated climate-driver summary including a ranked table of drivers and a written interpretation of a described temperature anomaly dataset
Climate change & Inquiry skills: investigations, data analysis, and evaluation of conclusions
Analyse a described set of regional climate projection data and state two likely impacts on water resources and two on agriculture
Evaluate the reliability of a climate projection by discussing resolution, model agreement and emissions-scenario assumptions
Distinguish between mitigation and adaptation and propose two strategies of each for a named region
Assess a media climate claim against the underlying data description and identify any misrepresentation
Your checkpoint
A 450-word climate impact and response report that analyses the described projection data, proposes two mitigation and two adaptation strategies, and evaluates one media claim
Inquiry skills: investigations, data analysis, and evaluation of conclusions & Earth's resources & Climate change
Design a full investigation on a resource or climate question, specifying aim, hypothesis, variables, sampling strategy, replication and risk controls
Select appropriate graphing and statistical techniques for three described datasets and justify each choice
Evaluate three described conclusions for validity, identifying confounding variables, sampling bias or overgeneralisation in each
Construct a structured evaluation of your own investigation design listing two strengths and two limitations
Your checkpoint
A complete investigation plan of 500 words with variable table, sampling plan and a separate evaluation section, self-assessed against a provided inquiry-skills rubric
Inquiry skills: investigations, data analysis, and evaluation of conclusions & Earth systems and their interactions & Earth's resources & Climate change
Synthesise content from all four domains into three integrated practice responses under timed conditions
Analyse unfamiliar data presented in a table or graph and produce a structured interpretation within ten minutes
Evaluate your own practice responses against mark-style criteria and list three recurring weaknesses
Revise the three weakest concepts identified in earlier weeks and demonstrate improvement with a short re-test
Your checkpoint
Three timed practice responses marked against criteria, plus a one-page error log listing three recurring weaknesses and the specific revision actions taken
Milestones
Week 2: Can draw the carbon cycle from memory, label two reservoirs and two fluxes, and explain one cross-sphere feedback without notes
Week 4: Scores at least 80% on a self-marked resource classification and reserve-calculation set, and correctly interprets a production trend graph
Week 6: Can explain two climate feedbacks, rank four drivers by contribution, and evaluate one projection's reliability in writing
Week 8: Completes three timed integrated responses and shows measurable improvement on the three weaknesses logged in the error log
