           C1.22 Crude Oil
• Describe this image using 4 quality
  sentences:
     C1.23 Crude oil fractions
• Rewrite this headline so it reads as a
  sentence:

 ‘Blast at Bangkok oil refinery triggers huge
 blaze’
          C1.24 Combustion
Convert these six sentences into as few sentences as
possible without losing any information – aim for three!

When hydrocarbons fuels burn, they react with oxygen
and release heat energy. They also produce light
energy. This is an oxidation reaction called combustion.
You can carry out experiments to detect the products of
a combustion reaction. One of the products of a
combustion reaction is carbon dioxide. Water is also
produced.
C1.25 Incomplete combustion
Into which paragraph in the following text would you put this
sentence: ‘Car exhausts are also a common source of carbon
monoxide.’ Why?

      Carbon monoxide is a product of incomplete combustion of
natural or petroleum gas. Inhaling the gas reduces the blood's ability
to carry oxygen, leaving the body's organs and cells starved of
oxygen.
      Common sources of carbon monoxide in the home include
faulty central heating systems, gas appliances and fires. Blocked
flues and chimneys mean the gas can't escape and is inhaled by the
unsuspecting individual.
      In the UK, about 50 people die each year in their homes from
accidental carbon monoxide poisoning.
           C1.26 Acid rain
• Describe what is happening in this
  diagram using 5 sentences:
         C1.27 Climate change
Put these sentences in the correct order:

• These gases include carbon dioxide, emitted by fossil
  fuel burning and deforestation, and methane, released
  from rice paddies and landfill sites.
• The greenhouse effect is the natural process by which
  the atmosphere traps some of the Sun's energy,
  warming the Earth enough to support life.
• Most mainstream scientists believe a human-driven
  increase in "greenhouse gases" is increasing the effect
  artificially.
                     C1.28 Biofuels
    Label the following statements as either ‘advantages’ or
    ‘disadvantages’

•   Biodiesel can be used in any diesel vehicle and it reduces the
    number of vibrations, smoke and noise produced.
•   They are non-toxic.
•   Biofuel may raise the price of certain foods, which are also used for
    biofuel such as corn.
•   Biofuel development and production is still heavily dependent on Oil.
•   As other plants are replaced, soil erosion will grow.
•   They are renewable.
•   A lot of water is used to water the plants, especially in dry climates.
•   Deforestation in South America and South Eastern Asia causes loss
    of habitat for animals and for indigenous people living there. There
    can be a reduction in fossil fuel use.
•   Biofuel operations help rural development.
•   Biodiesel is biodegradable.

         C1.29 Choosing Fuels
  Convert these six sentences into as few sentences
  as possible without losing any information – aim for
  three!

• Most of the fuels we use cause some pollution. Natural
  gas (which is mainly methane), petrol, kerosene and
  diesel oil (obtained from cruse oil) are all non-renewable
  fossil fuels. They all produce carbon dioxide and water
  when they burn completely. If incomplete combustion
  occurs, any of these fuels can produce carbon monoxide
  and soot. Some fuels contain impurities such as sulfur.
  Sulfur forms sulfur dioxide when it burns.
      C1.30 Investigating fuels
• Look at the text on page 177. Pick out the
  sentence starters that make this a well written
  evaluation.

  lesson. Use these words:

       C1.33 Polymerisation
• Write these key words and tick off the
  ones you are sure you know the meaning
  of:
• Flexible, cheap, insulator, shatterproof,
  tough, slippery, resistant, corrosion
• Extension – write one alternative word for
  each one. Use a thesaurus if you need to.
