Lesson Plan for Junior Secondary 1 - Basic Tech - Properties Of Material - Metals

### 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.
