**Lesson Plan: Classification of Metals**
**Class:** Junior Secondary 1
**Subject:** Basic Tech
**Topic:** Classification of Metals
**Duration:** 45 Minutes
**Objective:**
By the end of the lesson, students will be able to:
1. Understand the basic classification of metals.
2. Differentiate between ferrous and non-ferrous metals.
3. Identify common examples of ferrous and non-ferrous metals.
4. Describe some properties and uses of different metals.
**Materials Needed:**
1. Whiteboard and markers
2. Projector and laptop for presentation (if available)
3. Samples of metals (steel, copper, aluminum, etc.)
4. Handouts or worksheets on classification of metals
5. Textbook or reference book
**Lesson Outline:**
1. **Introduction (5 minutes)**
- Greet the students and take attendance.
- Briefly review the previous lesson on basic materials in technology.
- Introduce the day’s topic: Classification of Metals.
2. **Presentation (15 minutes)**
- **Definition of Metal:**
- Metal is a substance that typically has a shiny appearance, is a good conductor of heat and electricity, and can be hammered or cast into a shape.
- **Classification of Metals:**
- **Ferrous Metals:** Metals that contain iron.
- Examples: Steel, cast iron, wrought iron.
- Properties: Magnetic, prone to rusting, high tensile strength.
- Uses: Construction, tools, machinery.
- **Non-Ferrous Metals:** Metals that do not contain iron.
- Examples: Aluminum, copper, brass, lead, zinc.
- Properties: Non-magnetic, more resistant to corrosion, lighter than ferrous metals.
- Uses: Electrical wiring, beverages cans, aircraft bodies.
- Show samples of both ferrous and non-ferrous metals, if available.
- Project a classification chart for easier understanding.
3. **Activity (10 minutes)**
- Distribute handouts or worksheets on the classification of metals.
- Group Activity: Divide class into small groups and ask each group to discuss one specific example of either ferrous or non-ferrous metal, noting its properties and common uses.
- Each group will present their findings to the class.
4. **Discussion (10 minutes)**
- Ask students to compare and contrast ferrous and non-ferrous metals.
- Answer any questions students might have about the properties and uses of the metals.
5. **Conclusion (5 minutes)**
- Summarize the key points:
- The main types of metals: ferrous and non-ferrous.
- Examples, properties, and uses of each type.
- Emphasize the importance of knowing how to classify metals in technology and everyday life.
6. **Assessment:**
- Quick Quiz: Ask three questions related to the topic.
- Example: Name two ferrous metals.
- Example: What properties are common in non-ferrous metals?
- Example: Which type of metal is more resistant to rust?
- Collect worksheets for grading.
7. **Assignment:**
- Assign students to write a short essay or paragraph on one non-ferrous metal and its applications in everyday life. The essay should be submitted in the next class.
**Extension Activity:**
- For students interested in exploring further, suggest researching the recycling process of ferrous and non-ferrous metals and how it benefits the environment.
**Notes:**
- Ensure interactive participation throughout the lesson.
- Provide real-world examples to make the topic more relatable.
- Adapt materials and activities to suit the available resources and the student’s learning pace.
