The fossil fuels that we use to produce electricity and drive our cars have some big disadvantages. This means that in the future we will need to
search for ways of reducing the effects of fossil fuels on the environment, and search for new sources of energy to make electricity and to enable
us to drive our cars.
Task 1 Use of Fossil Fuels
Fossil fuels are burnt to provide energy.
In the table below write down the names of the types of fuels used to power our Power stations and Cars (Remember, electricity is not a type of
fuel, water is also not a type of fuel)
Power stations
Cars and lorries

Why do we use fossil fuels for energy http://www.youtube.com/watch?v=FbMo3ZsXZv4
Task 2 Burning fossil fuels
When we use fossil fuels we have to burn them to produce the energy. This is called combustion.
Write a word equation for the combustion of a hydrocarbon fuel, you may also wish to write a symbol equation if you can. Identify reactants and
products.
There are two types of combustion, complete and incomplete. Write word and or symbol equations labelling reactants and products to show the
difference between complete and incomplete combustion.

Task 3 Pollution from fossil fuels
When fossil fuels are burnt they produce some substances which increase pollution of the air. What do we mean by air pollution? (hint gases)
Find out the types of substances produced from burning fossil fuels, adding some extra information on how they are produced and the effects
on the environment and living organisms. You can use the resources below if you wish.

Pollution type
How it is formed
Effects on the environment (one sentence only)
Task 4 The effects of burning Fossil fuels
Three major effects of pollution from fossil fuels are Global Warming, Global Dimming and Acid Rain. Using the reference below or your own
research find out what causes each type of pollution and how it causes the effect. (You may write in the space below but you will need to draw
at least one diagram to show your understanding, complete a poster or PowerPoint, but the printout of a poster or PowerPoint must be
attached when you hand it in)

Global Dimming
Task 5 Fossil fuels in the Future
In the future we will need to clean up our act and reduce the effects of burning fossil fuels. Catalytic converters are fitted to cars to reduce
pollution produced by cars.
Using the Kerboodle resource or your own research.
http://www.bbc.co.uk/schools/gcsebitesize/science/21c/air_quality/improving_air_qualityrev3.shtml
http://www.bbc.co.uk/schools/gcsebitesize/science/add_edexcel/chemical_reactions/ratesrev4.shtml
Describe how a catalytic converter helps to reduce emissions in cars, a diagram that is labelled, or writing and chemical equations may help you
achieve higher marks.
Look at the article below
What is your opinion, who do you agree with and why?
Task 6 Biofuels
Biofuels are fuels made from plant or animal products. Biodiesel is made from plants. You can sometimes even use cooking oil from fast food
restaurants to fuel our cars. Biogas is another important fuel made from animal waste (poo!). Read the next information sheet.
Summarise the diagram above in no more than 3-4 sentences
Look at the sheet, can you highlight the pros/advantages of biofuels by ticking them, and highlight the cons/disadvantages of the others by
putting a cross on them.
Can you think of any more that you could add to this list, write them down below
Task 7 Biofuels by Fermentation
Ethanol can also be used as a biofuels; this is made by fermenting sugar. Can you describe and explain what fermentation is using a word
equation and how it is used to produce ethanol, a symbol equation would achieve higher marks. Identify all reactants and products
Task 8 Fuels of the future/alternative fuels
Hydrogen gas has interested Scientists as a fuel for the future. It burns with a clean flame as it contains no carbon
Hydrogen + Oxygen
Water
Can you write a balanced symbol equation for the reaction above, what are the advantages and disadvantages of using Hydrogen as a fuel.
What advantages and disadvantages of using Hydrogen as a fuel in cars can you think of; list them below in the table.
Advantages
Disadvantages
You cannot submit this via USB or email, you will need to print it out and hand this in to your teacher.
How to access the Kerboodle resource
This is an extra resource on top of their normal lessons and students are not disadvantaged by not being able to access this resource at home. If
you do not have access at home your child can easily gain access in school in one of the many ICT rooms. To access the resource your child will
need his/her normal computer access password, this is the one they use to log onto the school computer network.
The website address is http://live.kerboodle.com/secondary/common/Login.aspx, you will be then presented with the following login box, or
just type Kerboodle into a search engine it should take you to the link.
Your child will then need to enter their username and password into the boxes together with the
organisation code which is 1653. Their password is set to PASSWORD at the moment and they will
need to login and change it to prevent unauthorised access. They should be then able to login. If
they are unable to login, they should contact the ICT technicians who will be able to troubleshoot
the problem. Science teachers cannot solve this problem.
Once onto the site you will be presented with the following screen.
If they then click on Kerboodle books/my bookshelf, they can select the Science textbook for online viewing. If they wish to look at other
resources for the course they then should click on the Science course in the “my courses” area.
To change the password from password to one of your child’s choice you will need to click on your account. This needs to be done as soon as
you log on for the first time to prevent unauthorised access.
Once you are on the bookshelf. You should then click on the chemistry textbook which is illustrated to the left
of this text.
You will then get the following view. Then click on the
crude oil and fuels heading and it will take you to the
page as shown below
Use the arrows at the bottom of the screen to navigate
through the relevant pages.
Use the Tools to increase the size of the view etc they are
located on the right hand side.
This resource can also be accessed through the Science dept website (www.plantsbrookscience.org.uk) , the link to the kerboodle site is on the
KS4 resources page. The website also contains useful information about courses in the 6th form which your child may be interested in studying in
the future.
