Unit 6 Lesson 1 What Are Some Natural Resources?

Where it comes from?

Nature or man-made?

Natural Resources

• A natural resource is something that comes from nature that people can use.

• The air you breathe and the soil that crops grow in are natural resources.

• Other natural resources are used to make products you may use.

How Do We Use It?

• Everything we use comes from nature somehow, including food, water, electricity, and gasoline.

• Books, shelves, desks, toys—they’re all made from Earth materials.

• Even glass computer screens are made from sand.

Natural Resources

• A renewable resource is something in nature that can be replaced easily.

• Trees are a renewable resource. Paper and pencils are made from trees.

• We can plant more trees to make more paper and pencils.

How Do We Use It?

Going, Going, Gone

• Not all natural resources are renewable.

• Some natural resources will eventually be used up and gone.

• A nonrenewable resource is a natural resource that can be used up.

Going, Going, Gone

• Oil, coal, and natural gas are nonrenewable resources we use to produce different kinds of energy, including electricity.

• They are fossil fuels―fuels that form over many years from the remains of once-living organisms.

The Effects of Pollution

• Pollution is harmful substances in the environment.

• Smoke in the air is pollution.

• So are chemicals in water and garbage on land.

The types of Pollution

• What causes pollution? Pollution often results from people using natural resources.

• Burning fossil fuels, such as gasoline in cars and coal for energy, can cause air pollution.

• Land pollution is caused when people don’t put trash where it belongs.

• When chemicals and wastes run into water, they cause water pollution.

Going, Going, Gone

• How can we make sure these resources don’t disappear too quickly? We have to conserve them.

• Conservation is saving resources by using them wisely.

• What are some ways that you can use nonrenewable resources wisely? You can start by turning off lights when you don’t need them.

Reduce, Reuse, Recycle

• People need natural resources to survive, but we have to use them responsibly. You can help by remembering the “3 Rs”: reduce, reuse, and recycle.

• When you reuse something, you use it again.

• You can take a reusable bag to the grocery store.

• And you can use a refillable water bottle.

• When you recycle something, it is made into a new product.

• Glass, aluminum cans, paper, plastic bottles, and yard waste can all be recycled.

• Even the oil from cars can be recycled!

• What are some things you do or can do to help recycle?
