Lesson
2. Look at the illustration. What kind of energy does it use? What problem does it solve? 107 In order for students to define audience and purpose, ask them to work in groups and analyze the picture. Then ask them what they think about what it shows, the problem, and the solution. You might need to clarify that it uses air (wind) and not heat for it to work. 3. Work in small groups. Look at the list of materials. How have they been used in the illustration? Write key words in your notebook. This step will help prepare students for Activity 4. Get them to focus on how all the things are related and what their function is; e.g.: The paper cup is lifted because the card blades turn. The pencil is held on the table with card and tape. Monitor and use guiding questions to help students; e.g.: What does the string do? What is it tied to? 4. Read some of the steps to solve the problem. Use the verbs in the box to write 4 notes more. You could draw students’ attention to the 2 steps shown. Read them aloud together. Check understanding. Explain how the verbs are used in imperative to give the instructions and that they are followed by the nouns. Then do number three together with the students. If you think they are ready, let them do numbers 4, 5, and 6 on they own. Check as a class. Differentiated Instruction For this activity you can use the Open-Ended Question strategy to guide students with questions like: Which part do you think we should make first? What is the next step?

Achievement Write instructions. Teaching Guidelines • Define audience and purpose. • Analyze which and how many steps are needed to solve chosen problem. • Write sentences that describe steps and reflect how steps are connected. • Use their repertoire of words and expressions to write steps. • Write steps and a draft. Development What problem can you solve at home? Write on the board: What problem can you solve at home? Ask students to share ideas in pairs. Regroup pairs so that they form groups of four and share their ideas again. 1. Tell your group some steps to solve the energy problem in the world. You can start by eliciting different types of energy and fuel we use in our daily lives: oil, gas, electricity, coal, wood, solar, wind. Then ask students what the problems are of these. You could ask them which ones are cleaner, and which ones we have more of in the world.
