• READ
• A natural resource is anything which we take to
  use from the natural environment.
• fish, trees, wheat, oil, water, cotton, iron ore,
  gold etc. etc.
• When a natural resource is taken from the
  environment it is called a raw material e.g. the
  rock that iron ore is found in, a tree cut down
  in a forest, a fish caught in the ocean
• Before we can use many natural resources, they
  usually have to be extracted from the
  environment, processed in a factory, then
  transported to where we want to use it.
• What we need and want are called the demand. The
  natural resources are called the supply.

This kind of fishing is called trawling
Wheat farming
Producing Hydro-electric power
Drilling for oil
Logging

What are raw materials?

• COPY THE INFORMATION INTO YOUR ORGANIZER
• Definition
• When a natural resource is taken from the
  environment it is called a raw material.
• Examples
• -rock that contains iron (iron ore) taken from a
  mine

What are demand and supply?

• COPY THE INFORMATION INTO YOUR ORGANIZER
• If people need something, it is called the
  demand.
• Example There is a huge demand these days for
  micro chips/semi-conductors for modern
  technology.
• Finding and using natural resources to meet the
  demand is called the supply.
• Example Semiconductors are made from silicon. It
  is a common mineral found in sand. It is mined
  to meet the demand.

What is processing of raw materials?

• Most raw materials have to be changed before we
  can use them. This is called processing. Raw
  materials are processed to create products
  that we can use.
• COPY THE DEFINITION
• Processing changing a natural resource (raw
  material) so we can use it.
• Copy the chart on page 203 into your organizer to
  give examples of natural resources (raw
  materials), processing, and products.

An oil refinery
Fuels we get from oil
Be aware Oil also gives other products
