Year 12 ACT Environmental Science practice questions

This public preview page identifies the planned Year 12 ACT Environmental Science demo route and links it to curriculum coverage while the reviewed sample question set is being completed.

Sample-question focus

The planned public sample is for Year 12 ACT Environmental Science practice and will open after the demo questions are reviewed.

Skills covered

Practice Earth systems, pollution, biodiversity, sustainability, food and water security, climate change, energy use, and scientific inquiry.

Exercise and test mode

The route is public now; the exercise and test preview will become available after the curated question set is ready.

Curriculum link

Compare this demo with the ACT Year 11-12 Earth and Environmental Science curriculum page to scan related topics, subtopics, and pathway coverage.

Sample ACT BSSS Year 12 Environmental Science questions

These sample questions are visible on the page before login. They show ACT BSSS Year 12 Environmental Science biodiversity change, climate evidence, carbon budgets, energy transitions, risk models, and environmental decisions with diagrams, graphs, transects, and decision tables before opening the demo.

ACT BSSS Year 12 Environmental Science Biodiversity monitoring hard biodiversity-index table

1. A biodiversity table shows reserve north has index 0.63 and reserve south has index 0.58. Which reserve is slightly more diverse by this measure?

ACT 12 reserve biodiversity index north south 0.63
Choices
  • Reserve north
  • Reserve south
  • Both are zero
  • The lower index is always more diverse
Explanation:

The north index is greater than the south index, so it is slightly more diverse by this measure.

ACT BSSS Year 12 Environmental Science Climate data hard climate-trend graph

2. A rainfall-anomaly graph shows more years below average in the last decade than the first decade. Which conclusion is best supported?

ACT 12 rainfall anomaly trend first decade last decade dry years
Choices
  • Dry years became more frequent in the record.
  • Rainfall was above average every year.
  • The graph shows only pH.
  • No climate evidence is shown.
Explanation:

The graph shows a greater number of below-average rainfall years later in the record.

ACT BSSS Year 12 Environmental Science Carbon accounting hard carbon-budget diagram

3. A carbon-budget diagram shows 48 t CO2-e from transport and 18 t CO2-e avoided by active travel. What net transport emission remains?

ACT 12 active travel carbon budget 48 18 net
Choices
  • 30 t CO2-e
  • 66 t CO2-e
  • 18 t CO2-e
  • 48 t CO2-e
Explanation:

Subtract avoided emissions from transport emissions: 48 - 18 = 30 t CO2-e.

ACT BSSS Year 12 Environmental Science Energy systems hard energy-flow model

4. An energy-flow diagram shows a building using 240 MWh/year before retrofits and 180 MWh/year after retrofits. What saving is shown?

ACT 12 building retrofit energy flow 240 180 saving
Choices
  • 60 MWh/year
  • 420 MWh/year
  • 180 MWh/year
  • 25 MWh/year
Explanation:

The saving is 240 - 180 = 60 MWh/year.

ACT BSSS Year 12 Environmental Science Water management hard water-quality graph

5. A water-quality graph shows phosphate falling from 0.18 mg/L to 0.06 mg/L after wetland restoration. Which interpretation is supported?

ACT 12 wetland phosphate graph before after PO4
Choices
  • Phosphate concentration decreased.
  • Phosphate tripled.
  • The water became more polluted by phosphate.
  • The graph measures only temperature.
Explanation:

The plotted concentration after restoration is lower than before restoration.

ACT BSSS Year 12 Environmental Science Decision-making hard sustainability matrix

6. A climate adaptation matrix scores shade trees higher for heat reduction and habitat, but lower for water use than shade sails. What issue should be weighed?

ACT 12 heat adaptation decision matrix heat habitat water
Choices
  • Benefits and water demand trade off.
  • Only cost matters.
  • Trees have no environmental effect.
  • Both options have identical scores.
Explanation:

The matrix shows shade trees improve some criteria while using more water, so the trade-off must be considered.

For parents comparing ACT BSSS Year 12 Environmental Science support

ACT BSSS Year 12 Environmental Science practice should help students connect systems thinking to visible evidence: biodiversity change, climate evidence, carbon budgets, energy transitions, risk models, and environmental decisions. These examples preview that visual reasoning before the no-login Environmental Science demo.
