Unit 4 Life on Mars Welcome to the unit 教学设计 I. Teaching Objectives 1. Knowledge Objectives Students will be able to name space - related items (air tank, computer, dried food, etc.) correctly by matching pictures with terms. Students will understand the dialogue about living on Mars, mastering vocabulary like “gravity,” “special boots,” “dried food.” 2. Ability Objectives Improve speaking skills through discussing what to take to space and what living on Mars would be like. Enhance vocabulary application by using space - related terms in conversations. 3. Affective Objectives Inspire interest in space exploration and living on other planets. Encourage collaborative learning through pair discussions about Mars life. II. Language Knowledge 1. Key Words & Phrases Space - related items: air tank, computer, dried food, power pack, sleeping bag, space helmet, special boots, tent. Mars - living related: “less gravity,” “wear special boots,” “eat dried food,” “no pollution.” 2. Key Sentences “What should he take with him? Write the name of the item under each picture.” “What would it be like to live on Mars? There’s less gravity on Mars. We’d probably need to wear special boots.” 3. Key and Challenging Points Key Points: Correctly name space items and understand the dialogue about Mars life. Challenging Points: Using the new vocabulary naturally in conversations about Mars living conditions. III. Teaching Procedures (Total Duration: 45 Minutes) Step 1 Pre - activity (8 Minutes) Show a short video clip about space travel or Mars exploration. Ask students: “What do you know about Mars? What do you think people need to take if they travel to space?” Introduce the task: “Today, we’ll learn about space - related items and discuss what living on Mars might be like. Let’s start by naming the items for space travel!” Step 2 Picture - Term Matching (12 Minutes) Activity 1: Naming Space Items (8 Minutes) Students look at the pictures in Activity A and match them with the correct space - related terms (air tank, computer, etc.). Walk around to help with pronunciation and vocabulary understanding. For example, explain that an “air tank” provides oxygen in space. After students finish, check the answers together. Ask students to say the words aloud to practice pronunciation. Activity 2: Quick Vocabulary Review (4 Minutes) Do a quick drill: Show the pictures again randomly and have students say the corresponding terms. This helps reinforce memory. Step 3 Mars Life Dialogue (15 Minutes) Activity 1: Understanding the Dialogue (8 Minutes) Present the dialogue in Activity B. Read it with students first. Explain key vocabulary like “gravity” (the force that pulls things down) and “dried food” (food with most water removed). Ask students to identify the main points about living on Mars from the dialogue, such as “less gravity,” “need special boots,” “eat dried food,” “no pollution.” Activity 2: Pair Discussion (7 Minutes) Students work in pairs to practice the dialogue. Then, ask them to make their own conversations about living on Mars, using the model. For example, they can add more ideas like “How would we move around with less gravity?” or “What other problems might we face on Mars?” Walk around to listen and give feedback on vocabulary use and conversation flow. Step 4 Summary & Homework (10 Minutes) Summary (5 Minutes) Recap the space - related items and the main points about living on Mars from the dialogue. Emphasize the key vocabulary and how to use them in discussions about space. Homework (5 Minutes) Writing: Draw a picture of your ideal space travel gear and write a short description (at least 3 sentences) using the space - related terms. Reflection: Think about one more thing people might need to live on Mars that wasn’t mentioned in the dialogue and be ready to share it in the next class. IV. Assessment of Teaching Effectiveness Check the picture - term matching answers for accuracy in naming space items. Evaluate the pair dialogues for correct use of Mars - living vocabulary and meaningful conversations. Observe students’ participation in all activities to ensure understanding and engagement. V. Design Purpose Pre - activity: Activate students’ interest in space and build background knowledge. Picture - term matching: Help students learn and remember space - related vocabulary through visual - auditory practice. Mars life dialogue: Improve speaking skills and understanding of Mars living conditions, encouraging creative thinking. VI.
