### Lesson Structure:
#### 1. Introduction (10 minutes)
- Greet the students and explain the day's topics.
- Briefly introduce each topic to generate interest (floating objects, types of computers, and first aid).
#### 2. Science Session: Water - Objects that Float in Water (20 minutes)
- **Explain (5 minutes):** Introduce the concept of floating and sinking. Discuss why some objects float while others sink.
- **Demonstration (5 minutes):** Show objects and ask students to guess if they will float or sink. Place each object in the water to test predictions.
- **Activity (10 minutes):** Allow students to handle and test the objects themselves in small groups.
#### 3. Technology Session: Classification of Computers Based on Purpose (20 minutes)
- **Explain (10 minutes):** Discuss different types of computers (desktop, laptop, tablet, smartphone) and their purposes (e.g., work, communication, entertainment).
- **Visual Aids (5 minutes):** Show images or actual devices and explain their uses.
- **Activity (5 minutes):** Worksheet activity where students match pictures of computers to their uses.
#### 4. Health Session: First Aid (20 minutes)
- **Explain (5 minutes):** Introduce the concept of first aid. Discuss why it is important to know basic first aid.
- **Demonstration (10 minutes):** Show simple first aid practices such as cleaning a cut and applying a bandage.
- **Activity (5 minutes):** Allow students to practice applying bandages on a partner or a dummy.
#### 5. Recap and Review (10 minutes)
- Review the concepts learned in each session.
- Ask students questions to reinforce learning:
- Why do some objects float and some sink?
- Can you name a type of computer and its use?
- Why is first aid important?
#### 6. Closing (10 minutes)
- Summarize the key points from today's lesson.
- Answer any remaining questions.
- Assign a small homework activity, e.g., finding two more objects that float or identifying another type of computer at home.

### Additional Notes:
- Ensure to keep the class interactive by asking questions and encouraging participation.
- Safety comes first, especially during the first aid session. Supervise students closely during practical activities.
- Use simple language and examples suitable for Primary 2 students.
