Why might people want to live there in the future?” Introduce the task: “Today, we’ll explore a scientist’s vision of life on Mars by 2100—learn challenges, daily life, and new vocabulary!” Step 2 While - reading (18 Minutes) Activity 1: Skim for Main Ideas (7 Minutes) Students read the article quickly to identify: Problem on Earth: Overcrowded, polluted. Mars Solution: Build a better world; details about travel, survival, gravity, daily life. Walk around to clarify: “What’s the main reason people might move to Mars?” (Earth’s problems). Activity 2: Scan for Vocabulary & Details (11 Minutes) Vocabulary Matching (B1): Students match words (crowded, rapid, etc.) to meanings. Discuss answers, emphasizing context (e.g., “crowded” → Earth’s population issue). Comprehension Questions (B3): Students answer Simon’s questions (e.g., “Why move to Mars? How long to fly?”).
