Finite Resources & Recycling
有限资源与回收利用
Description
Explain that many raw materials (metals, fossil fuels, minerals) are finite resources, describe the environmental costs of extraction, and evaluate the benefits of recycling and the circular economy
Mastery Evidence
- Identifies examples of finite natural resources and explains why they are finite
- Describes the environmental impact of mining and fossil fuel extraction
- Explains why recycling metals saves energy compared to extraction from ores
- Discusses trade-offs between the cost of recycling and the benefit of resource conservation
Assessment Prompt
If your child was deciding whether to recycle an aluminium drinks can or throw it away, could they explain what goes into making new aluminium from scratch — and why recycling it uses much less energy?
