---
### Lesson Structure:
#### Introduction (10 minutes)
1. **Greeting and Warm-Up**
- Greet the students and take attendance.
- Start with a quick ice-breaker question related to the day's topics, e.g., "Can you name one thing we use air for?"
2. **Objective Overview**
- Briefly explain what topics will be covered during the lesson and what students are expected to learn.

#### Part 1: Air II (15 minutes)
1. **Discussion and Demonstration**
- Begin by asking students what they know about air.
- Demonstrate by blowing up a balloon to show that air is invisible yet essential. Discuss how air is made up of gases such as oxygen, nitrogen, and carbon dioxide.
2. **Activity**
- Distribute paper fans to the students and ask them to feel the air they make when they wave the fans.
- Ask them to imagine how life would be different without air.
3. **Questions and Answers**
- Engage students with questions, such as "What is air used for by humans and animals?" and "Can you see air?"

#### Part 2: Classification of Computers Based on Purpose (15 minutes)
1. **Introduction to Computers**
- Show images of different types of computers (e.g., personal computers, workstations, laptops, tablets) and explain their use.
2. **Explanation**
- **Personal Computers**: Used by individuals for tasks like homework, games, and internet browsing.
- **Workstations**: More powerful than personal computers, used for professional work like graphic design or scientific calculations.
- **Servers**: Computers that provide data to other computers, typically used in businesses.
3. **Interactive Activity**
- Ask students to name any computers they have seen and discuss their purposes.
- Create a simple matching game where students match images of computers with their purposes.

#### Part 3: First Aid (15 minutes)
1. **Explanation**
- Start by explaining what first aid is and why it is important.
- Show a basic first aid kit and identify common items (e.g., bandages, antiseptic wipes).
2. **Demonstration**
- Demonstrate how to apply a bandage and how to use antiseptic wipes on a minor cut.
3. **Role-Playing Activity**
- Divide students into small groups and give them scenarios to act out, such as treating a scraped knee or a minor burn.
- Guide them on how to properly apply first aid in those situations.

#### Conclusion and Review (5 minutes)
1. **Summary**
- Recap the main points of the lesson: what air is, different types of computers based on their purpose, and basic first aid procedures.
2. **Questions and Answers**
- Take any remaining questions from the students.
- Give a short quiz or verbal review to assess understanding.
3. **Homework Assignment**
- Ask students to draw or find pictures of different types of computers and label them.
- Encourage students to share a first aid story with their family and practice basic first aid at home under supervision.
---
#### Assessment:
- Evaluate the students based on their participation in activities and discussions.
- Check the accuracy and completeness of their matching game and drawings for homework.
- Observe their role-playing activities to assess understanding of first aid procedures.
---
#### Reflection:
- Take notes on what went well and what could be improved for future lessons.
- Ask students and possibly parents for feedback to tailor future lessons better.
