Natural Resources
What Are Natural Resources?
Natural resources are materials that exist in nature without us making them.
Sunlight, trees, rivers, and minerals are all examples.
We turn these raw materials into food, homes, clothes, and tools.
Renewable and Non‑renewable Resources
Renewable Resources grow back quickly or never run out.
- Sunlight powers solar panels.
- Trees can be planted again to become forests.
Non‑renewable Resources take millions of years to form and can run out.
- Coal, oil, and natural gas were created deep underground.
- Metals such as copper and gold are limited in the Earth’s crust.
Fun Fact: The Sun gives more energy in one hour than the whole world uses in a year!
Using and Protecting Resources
We clean water for drinking, grow food, and make electricity from rivers.
Wood becomes houses, paper, and furniture.
Mined minerals become phones, cars, and computers.
We can protect resources by:
- Turning off taps while brushing teeth.
- Planting a tree to replace one that was cut.
- Recycling metal cans so less mining is needed.
- Using solar or wind power instead of burning coal, which releases carbon dioxide and warms the planet.
Mini Experiment: Simple Water Filter
Materials: two clean plastic bottles, sand, small stones, cotton balls, coffee filter.
Steps:
- Cut the tops off the bottles and place a coffee filter inside each.
- Add cotton, then stones, then sand in layers.
- Pour dirty water slowly through the filter into a clear cup.
- Watch the water become clearer.
What you learn: Sand and stones act like natural riverbeds, cleaning water.
Quick Quiz

- A) Forest loss b) Mining needs c) Ocean waves
- True or False: All trees are non‑renewable because they die.
Every object you use started as a natural resource.
Explore your backyard, notice the resources around you, and remember that small actions keep Earth healthy for future explorers!
