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: one clean plastic bottle pre-cut by an adult, sand, small stones, cotton balls, a coffee filter, a clear cup, and water mixed with a spoonful of clean soil.
Steps:

1. Ask an adult to prepare the cut bottle. Place a coffee filter inside it and set it securely over the cup.
2. Add cotton, then stones, then sand in layers.
3. Slowly pour the soil-and-water mixture through the filter.
4. Compare how the water looks before and after. Never drink the filtered water. It may still contain microorganisms or dissolved pollution that you cannot see. Wash your hands and ask an adult to discard the materials.

What you learn: The layers can trap some visible particles. Real drinking-water treatment uses several controlled steps to remove particles and harmful contaminants.

Quick Quiz

1. Which resource never runs out?
   • A) Coal b) Sunlight c) Gold
2. Recycling metal helps reduce:
   • A) Forest loss b) Mining needs c) Ocean waves
3. True or False: All trees are non‑renewable because they die.

Answers: 1. B) Sunlight. 2. B) Mining needs. 3. False—forests can be renewable when regrowth and ecosystem health are protected, but they can still be depleted or damaged.

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!
