"Fuels and the Environment"
Fuels and the Environment Estimated grade Parent signature Student signature Teacher By signing above both parent and student acknowledge that they were able to access the resources and understand the importance of the work being the students own work. You should try to put any text into your own words and not just copy and paste chunks from the internet or from online textbooks. If you are unsure about how to complete this work please see your Science teacher as soon as possible and not the day or week before the home Learning Project is due in. 1 1 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 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 Types of Fuels used Task 2 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. http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/crudeoil/hydrocarbonsrev1.shtml Task 3 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. http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev4.shtml http://www.gcse.com/energy/fossil_fuels.htm www.kerboodle.co.uk AQA chemistry textbook See last page on how to access this resource. Pollution type How it is formed Effects on the environment (one sentence only) Task 4 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) http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev5.shtml http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev6.shtml http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev7.shtml www.kerboodle.co.uk Global Warming Acid Rain Global Dimming Task 5 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 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 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 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 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 advantages and disadvantages of using Hydrogen as a fuel in cars can you think of; list them below in the table. Advantages Disadvantages 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.co.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. Marking Ladder for Fuels and the Environment HLP Grade G Can list some examples of fuels used in Power stations and Cars and what is air pollution Grade F Can state what complete and incomplete combustion is using Grade E Can state that acid rain, Global Warming and Global dimming are caused by air pollution Grade D Can identify the advantages and disadvantages of Biofuels Grade C Can explain how Acid rain and Global warming occurs and their effects Grade C Can explain how Global dimming occurs and its effects Grade C Can describe using a word equation that for fermentation to occur yeast, a suitable carbohydrate source are needed together with a suitable temperature and that the products are Carbon dioxide, Ethanol plus some energy. Grade B Can write a fully balanced symbol equation for the complete combustion of Hydrogen and for all other equations where possible (Incomplete and complete combustion, Fermentation, Grade A Can explain how a catalytic converter works using a labelled diagram and the relevant symbol equations. Grade A* Can complete all of the above tasks using text in their own words where possible in an independent manner, all specialist terms are spelt correctly and the quality of the English is excellent. Answers are well explained and diagrams are used in an excellent way to enhance understanding. If you are unsure of any of these terms ask your Science teacher. Your Science teacher should explain these to you when this project is set.
