    10. Thursday, 15 September 2011 10 Plenary The names of 5 fuels What energy type is in fuels? What do machines all do?

    11. Thursday, 15 September 2011 11 Lesson 2:Energy Resourcesand Energy Transfer What are fuels and why are they useful?

    12. Thursday, 15 September 2011 12 Objectives and outcomes To gain a good knowledge of the fuels we use. To understand how we release the energy in fuels. Learn about energy types and transfer. Know that energy can be converted from one type to another. Know that energy transfers cause some energy to be wasted.

    13. Thursday, 15 September 2011 13 Fuels

    14. Thursday, 15 September 2011 14 What is a fuel?

    15. Thursday, 15 September 2011 15 Links

    16. Thursday, 15 September 2011 16 What fuels do these use?

    17. Thursday, 15 September 2011 17 Machines

    18. Thursday, 15 September 2011 18 Power Station: A huge machine

    19. Thursday, 15 September 2011 19 Fuel For A Power Station

    20. Thursday, 15 September 2011 20 Other power stations use…

    21. Thursday, 15 September 2011 21 The power station converts the chemical fuel energy into…

    22. Thursday, 15 September 2011 22 Energy out…

    23. Thursday, 15 September 2011 23 Steam Engine

    24. Thursday, 15 September 2011 24 Steam Locomotive

    25. Thursday, 15 September 2011 25 Energy transfer

    26. Thursday, 15 September 2011 26 Energy transfer

    27. Thursday, 15 September 2011 27 Getting the brain in action… Name one energy source we use at home that is not a fuel. What type of energy is in fuels? What happens to energy in a machine? Power stations convert the energy in fuel into electrical energy. Why do we get less energy out than we put in?

    28. Thursday, 15 September 2011 28 Checking your learning

    29. Thursday, 15 September 2011 29 Lesson 3 The safe use of a Bunsen Burner and preparing for an investigation.

    30. Thursday, 15 September 2011 30 Equipment Bunsen burners: 16 Matches Study guides Rubber bands for hair Exercise books Study guides Diary Writing & drawing equipment Homework

    31. Thursday, 15 September 2011 31 Objectives and outcomes Learn how to set up and use a Bunsen Burner safely. Learn how and why Bunsen Burners can make different flames. Confidently use a Bunsen Burner. Know how to be absolutely safe. Know how to change the heat output. Know about the energy transfer. Be able to draw a scientific diagram.

    32. Thursday, 15 September 2011 32 The safe use of a Bunsen burner Draw an accurate scientific diagram of a Bunsen burner. Annotate it to explain the functions of its parts.

    33. Thursday, 15 September 2011 33 RISK! THIS IS A DANGEROUS ACTIVITY! LISTEN to safety instructions. FOLLOW safety instructions.

    34. Thursday, 15 September 2011 34 Using the Bunsen: A quick check of your knowledge and skills.

    35. Thursday, 15 September 2011 35 Homework task 2 Devise an imaginative cartoon strip or flow chart to explain the safe setting up and use of a Bunsen burner. You might like to include some of the consequences of improper use. Why is this device called the ‘Bunsen’ burner? Write a short paragraph to describe who Bunsen was and what he did for science. (own words please)

    36. Thursday, 15 September 2011 36 How will the apparatus be set up?

    37. Thursday, 15 September 2011 37 Preparing for an investigation. Why does the Bunsen burner have a valve at its base? What fuel does the Bunsen burner use? What gas from the air is used when the burner is alight? Explain why different valve positions produce flames of different temperatures. Why is it essential to have the valve closed when the Bunsen is first lit? Why do you think different Bunsen burners may have different energy outputs? What effect will the Bunsen flame have on the temperature of the water in the beaker? Why is the thermometer not touching the base of the beaker? How will you support the thermometer safely? How can you use this apparatus to compare different Bunsen flames? How can you check your results for accuracy?

    38. Thursday, 15 September 2011 38 Plenary I can set up and use a Bunsen Burner safely. I know how and why Bunsen Burners can make different flames. I can use a Bunsen burner confidently . I know how to be absolutely safe. I know how to change the heat output. I know about the energy transfer. I can draw a scientific diagram.

    39. Thursday, 15 September 2011 39 Lesson 4 Comparing the energy output from different Bunsen flames

    40. Thursday, 15 September 2011 40 Equipment Bunsen burners 16+ Tripods with gauzes Matches Thermometers 16+ Measuring cylinders Goggles Results tables Rubber bands for hair 250 cm³ glass beakers Retort stands & clamps Calculators Timers Homework Exercise book Study guide Drawing & writing equipment Calculator Mini whiteboard, pen & eraser.

    41. Thursday, 15 September 2011 41 Objectives & outcomes Learn how to measure how much energy transfers. Know how to work out heat energy transfer. A set of accurate results. A written conclusion.

    42. Thursday, 15 September 2011 42 Planning Instructions Discuss and devise a fair test to compare the energy output of Bunsen flames (valve closed, valve slightly open, valve half-open and valve full open). Think your test through, then investigate. (No written work yet.) When you are certain that your results are accurate, analyse and conclude. (Book work: It’s your results and conclusion I need to see.)

    43. Thursday, 15 September 2011 43 Measurement of Energy Energy is measured in terms of the work it can do. 1 Joule of energy is required to move an object 1 metre using a force of 1 Newton In other words…. It takes 1 Joule to lift 1 Newton 1 metre ~   Energy and temperature rise It takes 4200 Joules of energy to raise 1kg of water through 1°C Or Energy = 4.2 x volume of water (cm³) x temperature rise (°C)

    44. Thursday, 15 September 2011 44 Using Excel

    45. Thursday, 15 September 2011 45 Analysis Discuss your results as a group. Work in pairs using a mini whiteboard to devise a conclusion. CLASS DISCUSSION ABOUT CONCLUSIONS (draft on screen) Redraft you conclusion in you exercise book. (Finish for homework)

    46. Thursday, 15 September 2011 46 Lesson 5 Do different fuels contain different amounts of Energy?

    47. Thursday, 15 September 2011 47 Equipment For demonstration only… Burning dishes Fuels to burn: Fire lighter Meths & cotton wool Wooden spills Sawdust Matches Thermometer Timer

    48. Thursday, 15 September 2011 48 Objectives To learn about the energy in different fuels. To revise how to calculate how much useful energy is released from different fuels. To learn about sustainable and non-sustainable fuels. To write a conclusion to an appropriate level.

    49. Thursday, 15 September 2011 49 Check your learning Self-evaluation

    50. Thursday, 15 September 2011 50 Do different fuels contain different amounts of Energy? You have seen a demonstration of different fuels burning.   Use the results from this demonstration to discuss what you saw.   Which of the fuels in the demonstration are derived from sustainable sources and which are not. All the fuels needed a little energy input before they started to burn. Did some fuels need more input than others? Which fuels released the most energy? How do you know? Was the test completely fair? Why?

    51. Thursday, 15 September 2011 51 Conclusion Check self evaluation Write a clear conclusion based on your observations and your scientific understanding.

    52. Thursday, 15 September 2011 52 Lesson 6 Energy converters
