### Lesson Plan: Properties of Materials - Metals
#### Class: Junior Secondary 1
#### Subject: Basic Tech
#### Topic: Properties of Materials - Metals
#### Duration: 60 minutes
**OBJECTIVES:**
By the end of this lesson, students should be able to:
1. Identify different types of metals.
2. Understand the physical and chemical properties of metals.
3. Recognize the uses of metals based on their properties.
**MATERIALS NEEDED:**
- Samples of different metals (aluminum, iron, copper, etc.)
- Magnet
- Charts or images showcasing different metals
- PowerPoint presentation (optional)
- Worksheets
- Notebook or Paper and Pens for students
**LESSON OUTLINE:**
1. **Introduction (10 minutes):**
- Greet the students and briefly introduce the topic, emphasizing its importance in everyday life.
- State the objectives of the lesson clearly.
2. **Teacher Input/Direct Instruction (15 minutes):**
- Discuss different types of metals commonly encountered (e.g., iron, aluminum, copper, gold, silver).
- Use visual aids like charts or a PowerPoint presentation to show images and uses of these metals.
- Explain the physical properties of metals (e.g., luster, malleability, ductility, conductivity, density).
- Define and provide examples of chemical properties of metals (e.g., reactivity with acids, corrosion, oxidation).
3. **Demonstration and Interactive Activity (10 minutes):**
- Show actual samples of metals and pass them around the class.
- Conduct a simple experiment with a magnet to demonstrate the magnetic properties of iron and other ferromagnetic metals.
- Discuss observations and relate them back to the properties explained earlier.
4. **Guided Practice (10 minutes):**
- Divide students into small groups and give each group a worksheet containing questions about the properties and uses of metals.
- Walk around the classroom, providing assistance and answering questions as needed.
5. **Discussion and Q&A (10 minutes):**
- Review the answers from the group worksheets together.
- Encourage students to ask questions and clarify any doubts.
- Discuss the significance of different properties of metals in real-life applications.
6. **Conclusion and Recap (5 minutes):**
- Summarize the key points of the lesson.
- Reinforce the importance of understanding the properties of metals in technology and industry.
7. **Assignment (Optional):**
- Assign students to write a short paragraph or create a poster about a metal of their choice, describing its properties and everyday uses.
**ASSESSMENT:**
- Participation in class discussions and activities.
- Accuracy and completeness of the group worksheet.
- Homework assignment (if given).
**REFLECTION:**
- Take a few minutes after the class to reflect on the lesson’s effectiveness.
- Note any areas where students seemed particularly engaged or confused, and consider adjustments for future lessons.
By following this lesson plan, students will gain a foundational understanding of metals, their properties, and practical uses, which is crucial for their knowledge in Basic Technology.
