Research activity 1: Renewable energy The pictures on page 37 show ways to generate energy in an environmentally friendly form. a) Work in groups of three or four. Research forms of renewable energy and deal with the following points: • How do they work? • What are their advantages and disadvantages? • What about the costs? • How far are they developed? b) Give a short presentation and tell your class more about your findings. Research activity 2: Are they avoidable? Every activity that uses energy sends carbon dioxide into the atmosphere, which traps heat and light from the Sun in the Earth’s atmosphere and hence increases the temperature. a) In groups, collect and compare examples of how people use energy in the course of a typical day. Differentiate between appliances that need electricity and activities that burn fuel, petrol or coal. b) Have a look at the energy-related activities listed below and find out if and why they increase or decrease carbon dioxide emissions. Extend the list with your own examples. • recycling aluminium cans • planting shade trees around houses • turning on the air condition • leaving windows open in the winter • leaving the TV running when nobody is watching • burning leaves in the garden • keeping car tires inflated • going to school by bus • using electric cars • … c) Examine your lists and discuss: • Which of these are necessities to organise important aspects in life? • Which of these are luxuries, things that enhance life but are not necessary? d) Discuss what you can do: • Which items are necessities in the lives of yourself and your family? • Which items would you be willing or able to give up to help improve the situation? Research activity 3: What could be done a) Find out about one of the following points: • a product or an idea that helps consumers to lower their carbon footprint • a local project to protect or improve the environment in the area where you live • interesting new research on some environmental issue b) Prepare a presentation in which you report about your findings. Follow this structure: • Topic sentence: What is the topic of your presentation? What is the main idea? • Supporting sentences: They explain the main points of the topic sentence, and they provide examples that help the listener to understand the main aspects of the topic. • Conclusive sentence: What are the results? What are the conclusions/the consequences? A conclusive sentence sums up the main points of your presentation. 1 Tip • Do not write your presentation/speech but prepare it with prompt cards so that you can talk about the topic freely. If you use such cards you can also rearrange the parts if necessary. • Use words that you are comfortable with. • Make sure you have an interesting beginning and an ending that takes up the same idea as the introduction. • Look into the audience. • Speak loudly and clearly. • Speak slowly. • Make short pauses to draw attention to what you have said. • Concentrate on the final sentence.
