Objective: 1. Knowledge: by the end of the lesson, Ss will be able to understand the passage, identify the main idea, and guess the meaning in context and express own ideas about sources of energy. 2. Skill: reading, writing, speaking II. Teaching aids: textbook, projector III. Method: communicative approach IV. Procedure: Content Activities I. Stabilization:(1 min) II. Check- up (3 mins): Combine these sentences, using preposition+ relative pronoun 1. The little girl has gone. I borrowed this pen from her. 2. The authorities gathered those villagers. They explained to them the importance of forests. 3. The ladder began to slip. I was standing on it III. Warm- up: ( 5 min) Matching the picture with the word 1. oil 2. solar energy 3. gas 4.wind power 5. electricity IV. Pre- reading( 10 mins) * Vocabulary: ( 7 mins) - Fossil fuel ['fɔsl fjuəl](n): nhiên liệu hóa thạch  example and picture: oil, coal, gas…. - Reserve [ri'zə:v](n): nguồn nguyên liệu (translation) - Alternative[ɔ:l'tə:nətiv](adj): thay thế ( translation) Eg: Some alternative sources of energy are nuclear energy, water - T checks up the old lesson ( language focus) * Key answer: 1. The little girl from whom I borrowed this pen has gone. 2. The authorities gathered those villagers to whom they explained the importance of forests. 3. The ladder on which I was standing began to slip. -T shows some pictures and asks Ss to match the picture with a suitable word. - Ss answer. - T leads in the new lesson: “ to understand our energy, today we are going to learn more about sources of energy”. - T teaches some new words. - T reads first. - Ss repeat in chorally and individually. power, wind power… - Geothermal heat [,dʒi:ou'θə:məl hi:t](n): địa nhiệt picture and explanation( energy comes from deep inside the earth) - Windmill ['winmil](n): cối xay gió(picture) - Sailboat ['seilbout](n): thuyền buồm( picture) - Unfortunately [ʌn'fɔ:t∫ənitli](adv): không may mắn( translation) Eg: Unfortunately, if the wind doesn’t blow, there is no wind energy. - Dam [dæm](n): đập ngăn nước( picture) - (to) release [ri'li:s] (v) = to be free: giải phóng, Eg: the sun releases large amounts of energy everyday. - Solar panel ['soulə 'pænl](n): tấm thu năng lượng mặt trời(picture) - Infinite (adj) = plentiful, abundant: dồi dào, phong phú, vô tận. Eg: Solar energy is infinite * Before you read: (3 mins) 1. What source of energy does each picture refer to?  It refers to wind energy, solar energy and water power. 2. What do you need energy for?  We need energy to live, cook, work, light, heat and cool the house and run the machines. V. While- reading( 20 mins) Task1:( 5 mins) Fill each blank with a suitable word. * Key answer: 1. released 3. energy 5. exhausted 2. alternative 4. limited Task 2: (10 mins) Table completion: clean and unlimited dangerous possible during the day time unlimited plentiful, clean, infinite and safe available no wind no wind energy expensive possible in some cases clean and unlimited Sources of energy Advantage(s) Disadvantage(s) Nuclear power Solar energy Water power Wind power Geothermal heat * Key answer: Sources of energy Advantage(s) Disadvantage(s) - T asks Ss to look at the pictures and answer some questions. - Ss answer. - T asks Ss to do the task1 individually. - T calls on some Ss to answer. - T gives feedback if necessary. - T divides the whole class into 2 groups: group A and group B. - Ss read the passage carefully. - Group A does advantage(s) and group B does disadvantage(s) of each alternative source of energy. - Ss base on the information in the text and cues - T has each group answer Nuclear power unlimited dangerous Solar energy Plentiful, clean, infinite and safe possible during the day time Water power Clean and unlimited Expensive Wind power Clean and unlimited No wind no wind energy Geothermal heat available possible in some places Task 3: Questions- answers: ( 5 mins) 1. What is our major source of energy? 2. Is this major source limited? Why? 3. How many sources of energy are mentioned in the text, and which one do you think has the most potential? * Key answers: 1. Our major source of energy is fossil fuels 2. Yes, it is. Because our demand is increasing very quickly and fossil fuels will be exhausted within a relative short time. 3. There are 6 sources of energy mentioned in the text. And I think solar power is the most potential. VI. Post- reading: ( 5 mins) Fill each blank with a suitable word Key answer: 1. energy 3. fuels 5. alternative 7. unlimited 2. one 4. limited 6. sources 8. environment VII. Home work( 1 min) - learn the new words by heart - translate the text into Vietnamese. - prepare for the next part - T gives feedback if necessary. - T asks Ss to work in pairs and answer some questions. - T calls on some Ss to write their answer on the board. - T corrects. - T asks Ss to do the task 4 in pairs. - T calls on some Ss to answer. - T corrects if necessary. 1.
