Lead - in (5 minutes) Activity: Play a short video about "Earth Hour" on the screen. The video shows the scenes of people all over the world turning off lights at the same time, and the beautiful starry sky without light pollution. Teacher's Instruction: "Dear students, look at the video carefully. Can you guess what this activity is What do you think people are trying to do by turning off the lights " Students' Activities: Watch the video attentively and think about the questions. Then, some students may raise their hands to answer. For example, they may say, "This activity is about saving electricity" or "People are trying to protect the environment." Design Intent: The vivid video can directly attract students' attention and arouse their interest in the topic. By asking questions, it stimulates students' thinking and curiosity, laying a good foundation for the following teaching.
Knowledge Presentation (10 minutes) Activity: Show some pictures on the PPT. The pictures include the logo of the World Wide Fund for Nature (WWF), some energy - saving devices like energy - saving lamps, and scenes of environmental pollution. Divide students into pairs to discuss the following questions: "What do these pictures have to do with energy conservation and environmental protection " "Do you know any global environmental protection activities " Teacher's Instruction: Walk around the classroom, listen to students' discussions, and give necessary guidance. For example, if students have difficulty expressing their ideas, the teacher can provide some key words like "save energy", "protect the environment", etc. Students' Activities: In pairs, students start to discuss the questions. They may point at the pictures and say, "The logo of WWF is related to environmental protection. They do a lot of work to protect wild animals and the environment." Or "Energy - saving lamps can help us save electricity, which is a way of energy conservation." Design Intent: The picture - based discussion can activate students' prior knowledge and help them associate the familiar elements with the new topic "Earth Hour". Pair - work can also improve students' communicative ability and cooperation ability.
Practice (15 minutes) Skimming (3 minutes) Activity: Ask students to quickly read the passage about "Earth Hour" and choose the main idea from several options on the handout. The options are: A. The origin of "Earth Hour". B. The significance of "Earth Hour". C. What "Earth Hour" is and how it develops. Teacher's Instruction: "Now, students, please read the passage quickly. Don't worry about the details. Just try to get the general idea and choose the correct option." Students' Activities: Read the passage rapidly and mark their choices. Design Intent: Skimming trains students' ability to grasp the overall meaning of the text, which is an important reading skill. Scanning (5 minutes) Activity: Present a series of questions on the blackboard, such as "When is 'Earth Hour' held every year ", "Which organization launched 'Earth Hour' ", "In which city did 'Earth Hour' start ". Let students scan the text to find the answers. Teacher's Instruction: "Read the questions carefully first, and then look for the answers in the text as quickly as possible. Pay attention to the key words in the questions." Students' Activities: Read the questions, scan the text, and write down the answers. Design Intent: Scanning helps students locate specific information accurately, improving their reading speed and information - seeking ability. Detailed Reading (7 minutes) Activity: Let students read the passage again carefully. Divide them into groups of four. Each group is assigned to analyze one part of the passage (the concept, origin and development, or suggestions for participation of "Earth Hour"). Then, each group needs to summarize the main content of their assigned part and fill in a form on the handout. The form includes columns like "Main Idea", "Key Information", and "New Words and Phrases". Teacher's Instruction: "Read the passage in detail this time. Work with your group members. Each group focuses on one part. Analyze it carefully and complete the form. If you have any questions, raise your hands." Students' Activities: Read the passage carefully, discuss with group members, and fill in the form. For example, for the part about the origin and development, they may write in the form: "Main Idea - The start and spread of 'Earth Hour'; Key Information - Launched by WWF in Sydney in 2007, and then spread to many countries including China; New Words and Phrases - launch, spread". Design Intent: Detailed reading enables students to understand the text comprehensively. Group work can cultivate students' cooperation ability, and filling in the form helps students organize and summarize information.
Production (10 minutes) Activity 1: Group Discussion (5 minutes) Activity: Show some pictures on the PPT, such as people having a candle - light dinner during "Earth Hour", children drawing pictures in the dark, and families playing board games without electricity. Divide students into groups of five. Let them discuss the following questions: "How can you participate in 'Earth Hour' What activities can you do during this hour How can your actions contribute to environmental protection " Teacher's Instruction: "Look at the pictures. Discuss with your group members. Each of you should share your ideas. Try to use the words and expressions we learned today." Students' Activities: In groups, students start to discuss. They may say, "We can turn off all the lights and electrical appliances at home. Then we can sit outside and enjoy the stars." Or "We can organize a story - telling activity in the dark with our friends. This can not only save electricity but also strengthen our relationship." Design Intent: The discussion based on pictures can make students think about practical actions they can take in "Earth Hour", which helps them internalize the knowledge and connect it with real life. Group discussion also improves students' oral communication ability. Activity 2: Debate (5 minutes) Activity: Divide the class into two big groups. One group supports the view that "Earth Hour is very meaningful and effective in protecting the environment", and the other group holds the opposite view. Each group has 2 minutes to prepare their arguments. Then, start the debate. Teacher's Instruction: "Now, let's have a debate. The two groups have different views. Prepare your arguments. Remember to use reasons and examples to support your views. Start!" Students' Activities: The supporting group may say, "During 'Earth Hour', a large amount of electricity is saved, which reduces the use of fossil fuels and thus cuts down carbon emissions. This is directly beneficial to the environment." The opposing group may argue, "One hour of turning off lights has little impact on the overall energy consumption. It is more of a symbolic activity rather than an effective measure to solve environmental problems." Design Intent: The debate can stimulate students' critical thinking. They need to analyze the issue from different perspectives, find evidence to support their views, and refute the opposite views, which greatly improves their logical thinking and language expression ability.
Summary and Homework (5 minutes) Summary (2 minutes) Activity: Invite a few students to summarize what they have learned in this class, including the knowledge about "Earth Hour", new words and expressions, and the importance of environmental protection. Then, the teacher makes a supplementary summary. Teacher's Instruction: "Who would like to share what you have learned today Let's review together." Students' Activities: Some students may stand up and say, "We learned about the origin, time, and significance of 'Earth Hour'. We also learned new words like'switch off' and 'energy conservation'." Design Intent: The summary can help students review and consolidate the knowledge they have learned in class, and also improve their generalization ability. Homework (3 minutes) Activity: Ask students to find more information about "Earth Hour" or other environmental protection activities on the Internet or in books, and share it with the class next time. Require students to make a poster about "Earth Hour" at home. The poster should include pictures, key information about "Earth Hour", and their own suggestions for environmental protection. Teacher's Instruction: "For homework, you need to do two things. First, find more information about environmental protection activities. Second, make a beautiful poster about 'Earth Hour'. I'm looking forward to seeing your works next class." Design Intent: The first homework task can expand students' knowledge and broaden their horizons. The second task, making a poster, can further enhance students' understanding of "Earth Hour" and their creativity, as well as their ability to integrate knowledge and art.
