Finite Resources & Recycling
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

“Finite resources are used faster than natural processes replace them. Recycling can reduce some extraction and waste, but also uses energy and depends on material and system.”

- Step 1. Identify the main material in each object.
- Step 2. Research or infer whether its source is finite or renewable.
- Step 3. Map extraction, manufacture, use, and disposal or recovery.
- Step 4. Rank a realistic reduce, reuse, or recycle action and justify the choice.
- Quick check. Use a new product. Success means your child identifies a resource, distinguishes reduce/reuse/recycle, and avoids claiming recycling has zero impact.
Worked example. An aluminum can begins with mined bauxite. Reusing a container can avoid a new item; recycling aluminum recovers material but still requires collection and processing.
Optional challenge. Evaluate a trade-off where a reusable option requires more material initially and identify what additional data is needed.
What to notice. Save a photo of one life-cycle map, or a short note recording the chosen action and trade-off.

Check understanding
- 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
“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?”
