Resource Management and Sustainability

This topic challenges students to act as modern geoscientists, weighing the complex environmental and societal trade-offs of our resource consumption.

• Socio-Scientific Issues
• 60 min · Small Groups

Fracking Proposal Debate

Students are divided into groups representing different stakeholders (e.g., energy company, local residents, environmental group, government) to debate a fictional proposal for a new shale gas extraction site in the UK. Each group researches and presents their arguments, focusing on geological, economic, and environmental evidence.

Evaluate the environmental impacts associated with the extraction of fossil fuels, such as acid mine drainage or oil spills.

Facilitation Tip

Provide role-play cards with key arguments to help students get started and stay in character.

What to look for

Write an essay evaluating the statement: 'The transition to renewable energy will create a new set of geological resource challenges that may be just as significant as those associated with fossil fuels.'

Activity 02

• Socio-Scientific Issues
• 90 min · Pairs

Lifecycle Assessment Poster

In pairs, students choose a common object (e.g., a smartphone, an aluminium can) and create a poster illustrating its lifecycle. They must research and present the geological resources required, the energy used in extraction and manufacture, and the possibilities for recycling or disposal.

Justify the importance of recycling metals in the context of resource sustainability and the circular economy.

Facilitation Tip

Encourage students to use quantitative data where possible to compare the environmental footprints of different stages.

What to look for

Students complete a concept map linking key terms such as 'circular economy', 'recycling', 'resource depletion', and 'sustainable management', explaining the connections between them.

• 45 min · Individual

UK Geothermal Hotspot Mapping

Using geological maps and data from the British Geological Survey (BGS), students identify areas in the UK with the highest potential for geothermal energy. They must justify their choices based on the presence of suitable rock types (e.g., granite batholiths) and high geothermal gradients.

Explain the geological principles behind geothermal energy as a renewable resource.

Facilitation Tip

Provide a simplified key for the geological maps to help students focus on the most relevant features.

What to look for

Students use a 'traffic light' system to rate their confidence in explaining the geological principles behind three different energy sources: coal, geothermal, and hydroelectric power.

A few notes on teaching this unit

Begin by grounding the concepts in familiar UK examples, such as the legacy of coal mining or the rise of offshore wind farms. Use case studies to move from local impacts to global supply chains. Encourage debate and critical thinking, emphasising that there are rarely simple 'right' or 'wrong' answers in resource management.

Upon completion, students will be able to critically evaluate the sustainability of different resource pathways and justify the role of geology in a green economy.

Watch Out for These Misconceptions

• Renewable energy has no environmental impact or connection to geology.

  All energy sources have an environmental footprint. Renewable technologies like wind turbines and solar panels require vast quantities of mined materials (e.g., rare earth elements, copper, silicon), and geothermal and hydroelectric power are directly dependent on specific geological conditions.

• Recycling completely solves the problem of resource depletion.

  Recycling is crucial for sustainability and significantly reduces the need for primary extraction, but it is not a perfect solution. The process itself requires energy, and not all materials can be recycled indefinitely without a loss of quality. It slows depletion, but does not eliminate it.

• Once a mine is closed, its environmental impact stops.

  The environmental legacy of a mine can last for centuries. Issues like acid mine drainage, where water reacts with sulfide minerals in waste rock, can pollute water sources long after mining operations have ceased, requiring ongoing management.
