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

Week 1

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

Week 2

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

Week 3

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

Week 4

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

Week 5

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

Week 6

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

Week 7

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

Week 8

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
