**Lesson Plan Outline:**
1. **Introduction (10 minutes)**
- Greet the students and introduce the day's topics.
- Explain the importance of learning about air, computers, and safety.
2. **Topic 1: Air (Wind) (25 minutes)**
- **Engage:** Ask students if they have ever felt the wind and what they think it is.
- **Explain:**
- Air is all around us even though we can't see it.
- Wind is moving air. It can be strong or gentle.
- **Explore:**
- Demonstration: Use a fan or blow on a piece of paper to show how air moves objects.
- Activity: Students take turns waving their hands in front of their faces to feel the air move.
- **Evaluate:** Ask students to describe what they learned about wind and how it moves objects.
3. **Topic 2: Classification of Computers by Generation (25 minutes)**
- **Engage:** Show pictures of old and new computers to pique interest.
- **Explain:**
- First Generation: Vacuum tubes (1940s-1950s).
- Second Generation: Transistors (1950s-1960s).
- Third Generation: Integrated Circuits (1960s-1970s).
- Fourth Generation: Microprocessors (1970s-present).
- **Explore:**
- Show brief videos or images of each generation of computers.
- Discuss how computers have evolved to become faster and smaller.
- **Evaluate:** Ask students to draw pictures of the "old" and "new" computers they saw.
4. **Topic 3: Safety Education (20 minutes)**
- **Engage:** Start a discussion: "What do you do to stay safe at home or school?"
- **Explain:**
- Define safety and explain why it's important.
- Basic safety measures: not touching hot objects, looking both ways before crossing the road, not talking to strangers.
- **Explore:**
- Role-play different safety scenarios (crossing the road, kitchen safety, stranger danger).
- **Evaluate:** Ask students to list three safety rules they should follow at home and in school.
5. **Review and Conclusion (10 minutes)**
- Recap the three topics covered: Air (Wind), the generation of computers, and safety education.
- Discuss any questions or confusion students might have.
- Provide praise and encouragement for their participation and understanding.
6. **Homework Assignment**
- Draw a picture of something that moves because of wind (like a kite or a sailboat).
- Write a sentence describing a safety rule at home or school.
**Materials Needed:**
- Fan or paper for wind demonstration.
- Pictures/videos of old and new computers.
- Paper and crayons for drawing activities.
- Props for role-playing safety scenarios.
**Assessment:**
- Participation in discussions and activities.
- Drawings and explanations about wind.
- Identification and differentiation of computer generations.
- Demonstrating understanding of safety rules through role-play.
**Notes:**
- Be mindful of each student’s participation; encourage shy students gently.
- Adjust the pace of the lesson based on student understanding and engagement.
**Reflection:**
- At the end of the lesson, reflect on what worked well and what could be improved for future lessons.
- Take note of any students who may need additional support or further challenges.
