Is this main source of energy limited ? How many sources of energy you know and what are they ? Which one you think has the most potential ? why ? * Correcting the mistakes , giving remarks and marking Answer keys Our major sources of energy is fossil fuels (oil , coal , natural gas) Yes, it is Because our demand is increasing very quickly and fossil fuels will be exhausted within a relative short time Lop11.com (2) The sources of energy mentioned in the text are: fossil fuels, nuclear energy, geothermal heat, solar energy, wind power, water power I think solar energy is the most potential energy of all the alternative sources of energy Presentation of the new materials SPECIFIC STAGES TIME 8ms 5ms TEACHER'S ACTIVITIES Warmer: Game: Right or wrong chair * Asking the students to work in two groups Five students from each group stand in two lines * Putting two chairs in front of the class Sticking the word: limited or unlimited on each chair * Saying out some sources of energy randomly (oil , wind power , natural gas , nuclear power , solar energy , coal , water power) * Asking the students to listen and decide which energy is limited and which is unlimited * Students take turns running to the right chair to sit down The group that has more points will win the game * Checking the students’ understanding of the instruction Expected answers: Limited Unlimited Oil Wind power Coal Natural gas Nuclear power Solar energy Water power Lead in: * Asking the students : Who can tell me again about the advantages and disadvantages of these sources of energy ? * Emphasizing on the students’ answers and introducing the new lesson * Writing the lesson down Unit 11 : SOURCES OF ENERGY Period 68 : SPEAKING Pre speaking: Activity 1: Pre-teach vocabulary * Introducing the new words to the students renewable [ri'nju:əbl] (a) có thể hồi phục lại (that is replaced STUDENTS' ACTIVITIES THE CONTENT OF THE LESSON * Working in two groups Five students from each group stand in two lines * Listening and deciding which energy is limited and which is unlimited * Taking turns running to the right chair to sit down Unit 11 : SOURCES OF ENERGY Period 68 : SPEAKING * Answering the questions * Writing the lesson down * Students write down the new words Lop11.com New words: renewable [ri'nju:əbl] (a) có thể hồi phục lại # nonrenewable reactor [ri:'æktə] (n) lò (3) TIME TEACHER'S ACTIVITIES STUDENTS' ACTIVITIES phản ứng a nuclear reactor : lò phản ứng hạt nhân naturally) # non-renewable (explanation) reactor [ri:'æktə] (n) lò phản ứng radiation [,reidi'ei∫n] : a nuclear reactor : lò phản ứng hạt nhân (translation) phóng xạ hydroelectricity [,haidrouilek'trisiti] thủy điện radiation [,reidi'ei∫n] : phóng xạ (example) hydroelectricity[,haidrouilek'trisiti] thủy điện (using the power of water to produce electricity) (picture) 5ms 5ms * Asking the students to read the words after the teacher in chorus Activity 2: Task 1: (p.127) * Asking the students to work in pairs to look at Task and decide the source of energy advantage or disadvantage * Going around the class and giving help if necessary * Calling some students to read out the statements Answer keys: D D D A D A D While speaking: Activity 1: Repetition Task 2: (p.128) * Providing students with the model on the handout on B/B so that students can make conversations about the sources of energy like this Model: A: I think / believe that wind power can be alternative sources of energy B: Why you think / believe so ? A: Because our major sources of energy are running out while the wind is abundant and unlimited B: I know it is also clean and safe to the environment However, it is not available when there is no wind * Asking the students to practice the model in pairs simultaneously * Going around the class and giving help if necessary * Calling some pairs to the front of the class to act out the conversation Activity 2: Substitution THE CONTENT OF THE LESSON * Reading the words after the teacher in chorus * Working in pairs to look at Task and deciding the source of energy advantage or disadvantage * Some students read out the statements Task (Page 127) Decide the source of energy advantage or disadvantage Answer keys: D D D A D A D * Writing down the model Task 2: (p.128) Talk about the advantages and disadvantages of using each alternative source of energy * Practicing the model in pairs simultaneously * Some pairs go to the front of the class to act out the conversation Lop11.com (4) TIME 10 ms 1m TEACHER'S ACTIVITIES Task 2: (p.128) * Asking the students to work in pairs to act out their conversations with sources of energy such as oil , wind power , natural gas , nuclear power , solar energy , coal , water power * Going around the class and giving help if necessary * Calling some pairs to the front of the class to act out the conversation Post speaking Task : (Page 128) Group discussion * Asking the students to work in pairs to talk about the way how to save the present source of energy * Giving the students some suggested ideas: + Try to reduce the amount of water bill or electricity bill by cutting power such as lights, conditioner when necessary + Don’t cook with electricity + Mare sure that there are no cracks in the pipes … Suggested speech: Who can imagine our life without electricity ? Nowadays we use electricity in many fields in our daily life so if there were no electricity, our life would be very , very difficult I think it’s time we saved electricity For example, we can save water by using water less ; we cut down light bulbs in the house if unnecessary HOMEWORK: * Asking the students to write down the homework + Prepare LISTENING + Write a composition to talk about the alternative source of energy that you think is the most feasible one for our country STUDENTS' ACTIVITIES THE CONTENT OF THE LESSON * Working in pairs , acting out their conversations with sources of energy such as oil , wind power , natural gas , nuclear power , solar energy , coal , water power * Some pairs act out the conversation * Working in pairs to talk about the way how to save the present source of energy * Some pairs go in front of the class to act out Task : Page 128 Talk about the way how to save the present source of energy * Writing down the homework HOMEWORK: + Prepare LISTENING + Write a composition to talk about the alternative source of energy that you think is the most feasible one for our country Self-evaluation: ……………………………………………………………………………………………………………………………………………………………………………………………………………………………… ……………………………………………………………………………………………………………………………………………………………………………………………………………………………… ……………………………………………………………………………………………………………………………………………………………………………………………………………………………… ……………………………………………………………………………………………………………………………………………………………………………………………………………………………… ……………………………………………………………………………………………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………………………………………………………………………………………… Lop11.com (5)
