### **Lesson Outline:**
**Introduction (10 minutes):**
1. **Greeting and Attendance:**
- Start with a warm welcome and take attendance.
2. **Introduction to Magnetism:**
- Briefly explain what magnetism is.
- Interactive Q&A: Ask students for examples of where they've seen or used magnets.
---
**Body (40 minutes):**
1. **Explanation (10 minutes):**
- **Types of Magnets:**
- Describe permanent and temporary magnets.
- Show examples of bar and horseshoe magnets.
- **Magnetic Fields and Poles:**
- Explain with diagrams the concept of magnetic fields.
- Discuss the North and South poles of a magnet.
2. **Demonstration (10 minutes):**
- **Magnetic Attraction and Repulsion:**
- Show how like poles repel and unlike poles attract.
- Use a compass to demonstrate the magnetic field around a bar magnet.
- **Iron Filings Experiment:**
- Place a magnet under a sheet of paper and sprinkle iron filings on top to visualize the magnetic field lines.
3. **Group Activity (10 minutes):**
- **Simple Magnetic Experiments:**
- Divide students into small groups. Provide each group with a variety of objects (metal and non-metal).
- Ask students to test which objects are attracted to the magnets.
- Record observations on the provided worksheet.
4. **Application Discussion (10 minutes):**
- Discuss real-life applications of magnets: in electronics, medicine (MRI scanners), industrial lifting, etc.
- Engage students in thinking about where else magnets are useful and why magnetism is important in technology.
---
**Conclusion (10 minutes):**
1. **Review Key Points:**
- Recap the definition of magnetism, types of magnets, and magnetic fields.
2. **Q&A Session:**
- Address any remaining questions from the students.
- Clarify any misunderstandings.
3. **Assignment:**
- Homework: Write a short paragraph on one technological application of magnets, explaining its importance.
- Optional: Create a simple magnet-based game or contraption and bring it to the next class to demonstrate.
4. **Wrap-Up and Closing:**
- Thank students for their participation.
- Give a preview of the next lesson topic.

### **Assessment:**
- **Formative Assessment:**
- Observe student participation and engagement during the activities.
- Check worksheets for accuracy and completeness.
- **Summative Assessment:**
- Review the written homework assignment for understanding and application of magnetism concepts.
---
### **Differentiation:**
- **For Advanced Students:**
- Challenge them to research and present on more complex applications of magnetism (like magnetic levitation in trains).
- **For Struggling Students:**
- Provide additional visual aids and simplified explanations.
- Offer one-on-one guidance during group activities.
---
### **Reflection:**
- At the end of the lesson, take notes on what went well and what can be improved for future lessons.
- Adjust instructional strategies based on student feedback and performance.
