It refers to wind energy, solar energy and water power What you need energy for? We need energy to live, cook, work, light, heat and cool the house and run the machines - T asks Ss to look at the pictures and answer some questions - Ss answer V While- reading( 20 mins) Task1:( mins) Fill each blank with a suitable word * Key answer: released energy exhausted alternative 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 Nuclear power Solar energy Water power Wind power Geothermal heat Advantage(s) Disadvantage(s) Lop11.com - T asks Ss to the task1 individually - T calls on some Ss to answer - T gives feedback if necessary - T divides the whole class into 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 (3) * Key answer: Sources of energy Nuclear power Solar energy Water power Wind power Advantage(s) Disadvantage(s) unlimited Plentiful, clean, infinite and safe Clean and unlimited Clean and unlimited available dangerous possible during the day time Expensive No wind no wind energy possible in some places Geothermal heat Task 3: Questions- answers: ( mins) What is our major source of energy? Is this major source limited? Why? How many sources of energy are mentioned in the text, and which one you think has the most potential? * Key answers: Our major source of energy is fossil fuels Yes, it is Because our demand is increasing very quickly and fossil fuels will be exhausted within a relative short time There are sources of energy mentioned in the text And I think solar power is the most potential VI Post- reading: ( mins) Fill each blank with a suitable word Key answer: energy fuels alternative unlimited one limited sources environment VII Home work( min) - learn the new words by heart - translate the text into Vietnamese - prepare for the next part Picture of warm- up: oil: - T gives feedback if necessary 2.solar energy: Lop11.com - 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 the task in pairs - T calls on some Ss to answer - T corrects if necessary (4) gas: 4.wind power electricity: Pictures of vocabulary: Fossil fuel: Windmill: sailboat geothermal heat dam solar panel Đà Nẵng, ngày 03/02/2010 BCD.TTSP GVHD SVTT Đặng Thị Hương Lop11.com (5)
