教教 案案 教学基本信息 课题Unit 8 Green Living(8) - Viewing Workshop 学科English学段：高中年级高一 教材书名：普通高中教科书英语必修第三册 出版社：北京师范大学出版社 出版日期：2019 年 8 月 教学目标及教学重点、难点 By the end of the lesson, students will be able to: 1.extract detailed information about solar energy from the video; 2.talk about how solar energy changes into other forms of energy and how solar energy causes matter on Earth to change into other forms. 重点： Students watch the video about solar energy and extract detailed information. 难点： The video might be difficult to some students to understand. 教学过程(表格描述) 教学环节主要教学活动设置意图 Step 1 Lead-in T shows Ss the picture of an interesting new product found online and asks Ss to guess what it is and then explains it - a solar charger which can charge mobile phone with solar energy T asks Ss to find what is in common after showing other products in daily life: a solar water heater, streetlights, and a calculator. T explains that all these products use sunlight as power. Arouse students interest Lead students to observe and compare Lead to the topic of todays class Step 2 Activate and share T asks Ss questions and discusses: 1. What is solar energy? 2. What do we use solar energy for? 3. What forms of energy can solar energy change into? Activate background knowledge Step 3 View and learn T leads Ss to watch the short video for the first time and decide which of the following topics are motioned: A. the definition of solar energy B. some products using solar energy C. solar energy can change into different forms T explains some keywords mentioned in the video with pictures: 1. solar panel 2. magnifying glass T leads Ss to watch the video again and complete the information. 1. Solar energy is energy that ___________ and it is View to get the general idea Prepare students with necessary vocabulary View to get detailed information what makes you feel _______ in summer. 2. Solar energy is what causes solar panels to turn sunlight into ________. 3. Solar energy is what sets a piece of paper _________ under a magnifying glass. 4. We see solar energy as _______ and we feel solar energy as ______. T leads students to pay attention to what solar energy can do to wind and plants, explains some keywords mentioned in the video with pictures: 1. grind grain 2. windmill 3. pump water 4. sailboat T leads Ss to watch part of the video again and choose the correct information to complete the diagram. Prepare students with necessary vocabulary View to get detailed information Step 4 Consolidate the information T leads Ss to look at the information we just have learned and introduces using mind maps to organize the idea. T asks Ss to try to organize what we just learned using a mind map. T shares a mind map and leads student to explain how solar energy changes into other forms using the mind map. Organize the information Consolidate the information and practice speaking Step 5 View and learn T leads Ss to watch the last part of the video and complete the flow chart. T explains some keywords mentioned in the video with pictures and explanations: 1. melt 2. liquid 3. vapour 4. sleet 5. hail T leads Ss to read the keywords in sentences together. View to get detailed information Learn the language Step 6 Consolidate the information T shows Ss a picture and asks students to mark how solar energy causes matter on Earth to change on the picture. T shows Ss one possible way of the water cycle and try to explain the process with the picture. Consolidate the information and practice speaking Step 7 Summary T gives a brief summary of what we have learned: What forms of energy can solar energy change to; How solar energy causes matters on Earth to change into other forms. Summarize the whole class Step 8 Extra information T shares some data from the annual report from the United Nations Environment Program (UNEP) published in 2019, telling Ss that solar and wind power have been gradually increasing to become a bigger source of energy over the whole world. China ranks top on the capacity of using clean power, and China is leading the trade to build more facilities for using solar and wind power. Provide more information about solar energy HomeworkTry to explain the information about solar energy we have learned today using the mind map and the picture; Search online to find ways we can use solar energy and share it with your classmates. Consolidate and use what we have learned必修三 Unit 8 Green Living (8) 高一年级 英语 Viewing Workshop Solar energy charger using power from an engine or a machine to do a particular kind of work 机械的；机械驱动的 mechanical energy Wind has mechanical energy which is the energy of moving objects. Check the answers gives the cow energy _________ energy Check the answers gives the cow energy chemical energy Summary Mind mapping an effective way A mind map (or mind-map) is a diagram used to represent and organize words and ideas linked to each other. It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, and decision making. What makes a mind map so effective? It allows us to use both sides of our brains at once. The left side of the brain controls logic, analytics, and details. It is very structured and organized. The right side is creative, imaginative, and likes to think freely. When someone says “think outside the box”, what they really mean is to move away from the left side of your brain for a while and allow your brains right side to daydream, explore, and think about the “bigger picture.” An example Try to use a mind map to reorganize the ideas we have learned about: What forms of energy can solar energy change into? One possible way Solar energy can be seen as can be felt as causes solar panels to turn sunlight into causes wind to form helps plants and animals to make light heat electricity mechanical energy chemical energy My version My version My version My version Explain how solar energy changes into other forms using your mind map Watch the rest part of the video and complete the flow chart melt If something solid melts or if heat melts it, it becomes liquid. vapour a mass of very small drops of a liquid which float in the air Watch it again and check your answers Check the answers Check the answers icewater water Check the answers airclouds Earth Check the answers ice water water airclouds Earth sleet half-frozen rain that falls when it is very cold 冻雨 雨夹雪 hail frozen raindrops which fall as hard balls of ice Read the sentences together Solar energy can melt ice and change it to liquid water. Energy from the Sun causes liquid water to change into water vapour that becomes part of the air which eventually turns into clouds. Read the sentences together When the clouds get heavy, water falls back to Earth as rain, sleet, hail, or snow. Solar energy lights and heats the Earth and provides energy for all living things. Practice ice water water airclouds Earth flow chartpicture Use simple markings to show how solar energy causes matter on Earth to change and then explain your markings solar energy ice liquid water liquid waterliquid water water vapour cloud rain snow water water cyclecycle Summary Solar energy a source of clean energy / renewable energy The annual report from the United Nations Environment Program (UNEP) 19 June 2019 Homework Explain what we have learned about solar energy using the mind map and the picture.
