Active learning ideas
This topic examines the physical and biological toll of extracting Earth's resources. Students analyze how large-scale operations like open-cut mining, fracking, and dredging can lead to habitat fragmentation, soil erosion, and the contamination of water systems. In the Australian context, this often involves studying the impact of mining on the Great Barrier Reef catchments or the effects of coal seam gas extraction on the Great Artesian Basin.
Activity 01
Students use trays of soil mixed with 'sulfide minerals' (represented by safe substitutes) and water to observe how acidity changes. They test various 'remediation' materials like lime to see which best neutralizes the runoff.
How does open-cut mining alter local ecosystems?
Activity 02
Set up a courtroom scenario where a company wants to expand a mine into a high-biodiversity area. Students take roles as ecologists, lawyers, traditional owners, and miners to argue the environmental costs versus economic benefits.
What are the impacts of resource extraction on groundwater?
Activity 03
Display satellite images of various Australian mine sites (e.g., Ranger Uranium Mine, Kalgoorlie Super Pit). Students circulate and use sticky notes to identify visible environmental impacts like tailings dams, vegetation clearing, and road networks.
How can we measure biodiversity loss in mining regions?
A few notes on teaching this unit
Watch Out for These Misconceptions
Environmental damage from mining is only at the surface.
Mining often affects deep aquifers and can cause long-term chemical changes (like acid mine drainage) that persist for centuries. Hands-on modeling of groundwater flow helps students visualize how underground contamination spreads far beyond the mine site.
Once a mine is closed, the environment immediately returns to normal.
Ecosystem recovery can take decades or centuries, and some changes are permanent. Peer discussion of 'legacy mines' helps students understand that environmental consequences often outlast the economic life of the project.
Methods used in this brief
Waste Management and Pollution
Students investigate the generation, treatment, and disposal of industrial and domestic waste. The topic covers the movement of pollutants through the atmosphere, biosphere, and hydrosphere.
8 methodologies
Sustainable Management and Rehabilitation
This topic focuses on the strategies used to rehabilitate degraded landscapes and promote sustainable resource use. Students evaluate the success of various environmental restoration projects.
