2. **Feather Game:**
- Give each child a feather.
- Ask them to blow gently on the feather to see how it moves with the air.
3. **Plastic Bag Parachute:**
- Hold a plastic bag, lift it up and then let it go.

---
**Activity 3: Interactive Discussion (5 minutes):**
1. **Question and Answer Session:**
- Ask the children where they think they can find air (in the classroom, outside, etc.).
- Discuss how important air is for breathing and for plants and animals.
2. **Funny Faces:**
- Encourage the children to take deep breaths and then blow out making funny sounds.

**Conclusion (5 minutes):**
1. **Recap:**
- Summarize the main points: Air is everywhere, we can feel it but not see it, and air helps things move and float.
2. **Goodbye Song:**
- Sing a short, cheerful goodbye song to wrap up the lesson.
3. **Homework (Optional):**
- Ask the children to find examples of air at home and share with the class the next day (e.g., blowing on a tissue paper).
---
**Assessment:**
- Observe children's participation in activities.
- Ask simple questions to check their understanding (e.g., "Can you feel the air?", "What happened to the balloon when we let it go?").

**Note for Teachers:**
- Ensure all activities are done in a safe manner.
- Be ready to guide and assist children during activities to keep them engaged and excited.
- Be patient and use positive reinforcement to encourage participation.
