UNIT 11 SOURCES OF ENERGY PART A: READING A.OBJECTIVES: Aims : - Helping students to understand the importance of saving energy and using alternative sources of energy. - Helping students to use the words related to the sources of energy through reading and writing. Vocabulary : fossil fuels, alternative, nuclear energy, geothermal heat/energy, solar power/panel, potential, to release, to create, exhausted, limited, plentiful, infinite Teaching Aids: pictures of sources of energy; projector (if available); textbook B.PROCEDURE: T Contents T & Ss’activities I). WARM UP: (5 MINUTES) Al the pictures should show different kinds of producing energy, such as wind power, solar energy, hydroelectric plant, etc. Write the words of different sources of energy on the board and ask students to match the words with the right pictures. Teacher may use the pictures in the Unit 11 Textbook page 124, or provides some mores pictures on cardboard or by projector. Students look at the pictures on the board Check the results and correct them if necessa(or in their books) and try to distainguish the sources of energy. II). PRE-READING: (10 minutes) - What do we need energy for? - What kind of energy is the most popular in Vietnam? 1.Vocabulary: fossil fuels(n) : nhien liêụ hoá thạch alternative (a): thay th ê nuclear energy (n) : n ăng l ư ơng nguy ên t ư geothermal heat/energy(n) : h ơi nong đ ịa nhi êt solar power/panel(n): Tam thu năng l ư ơng m ăt trơì potential (n) Tiem n ăng to release (v) th ải ra to create(v) : t ạo ra Exchange with their partners and match the words given with the right pictures. Ss Listen to the teacher's comments and repeat the words. Teacher explains some important words using pictures or giving meaning (some words need to be described in Vietnamese, especially to students of lower-level classes). Teacher ask these questions and has students exhausted(a) c ạn ki ẹt limited,(v) plentiful(a) infinite(v) Suggested answers: - We need energy to light and warm our houses, run automobiles and other machines, operate factories, and so on. - The most popular kind of energy in Vietnam is from oil. We also use power produced by hydroelectric plants. III). WHILE READING: (25 MINUTES) 1.Task 1:The words in the box all appear in the passage .Fill in the work in groups before giving their answers: Students get to understand these words: fossil fuels; alternative; solar panel; dam; nuclear; available; potential; limited; unlimited Students copy the words in their notebooks after the teacher's corection on the board. Students work in groups discussing the teacher's questions. Teacher has students blank with a suitable word( Use dictionary when necessary) Suggested answers: 1. released 2. alternative 3. energy 4. limited 5. exhausted 2.Task 2: Scan the passage and write down the advatages and disadvantages of each altenative source of energy Suggested answers: Sources Advantages Disadvant. listen to the recording of the passage two times, then read it in silence. (Teacher should go round to check and give help where necessary.) Students discuss Task 1 with their partners. Teacher has students work in pairs and complete Task 1 (pp. 125 - 126, Textbook). Teacher has students work in pairs studying the table in Task 2 (pp. 126, Textbook) and then discussing the advantages Nuclear unlimited dangerous Solar Plentiful and infinite, clean Not strong enough at present Water clean expensive Wind Clean, safe not always available Geothermal Clean Not available *Task 3: Answer the questions: 1. How many sources of energy are mentioned in the passage? What are they? 2. In your opinion, which one is the most potential? Why? Suggested answers: 1.These sources of energy are and Students listen to the recording and then read the text in silence. Students discuss the table with their partners and try to find the answers to Task 2. Students reread the text and group work to find the answers. Teacher has students read the passage again then ask mentioned in the passage: fossil fuels, nuclear, geothermal, solar, water, and wind power. 2. In my opinion, solar energy is the most potential because it is clean, safe and not expensive, and people can get it almost everywhere on earth. (There can be different answers to this questions.) IV). POST-READING: (5 minutes) Teacher has students work in pairs and complete the summary of the text on pages 126&127 in Textbook. Suggested answer: 1. energy 2. one 3. fuels 4. limited them to work in groups in order to work out the answers to theses questions: Students reread the text and group work to find the answers. 5. alternative 6. sources 7. unlimited 8. environment Homework: Teacher has students write a short paragraph to express their own choice of the alternative source of energy including some reasons for their choice. Students read the summary and discuss the completion with their partners. .
