**Lesson Plan: Basic Tech for Junior Secondary 2**
**Topic: Metalwork Machines**
**Duration:** 60 minutes
### **Objective:**
By the end of the lesson, students will be able to:
1. Identify different types of metalwork machines.
2. Understand the basic functions of each metalwork machine.
3. Demonstrate the basic safety protocols for operating metalwork machines.
### **Materials Needed:**
- Whiteboard and markers
- Projector and computer
- Metalwork machine images/videos (Lathe, Milling Machine, Drill Press, Grinding Machine)
- Safety gear (goggles, gloves, etc.)
- Handouts with summary notes
- Sample metal pieces
### **Lesson Plan Outline:**
#### **Introduction (10 minutes)**
1. **Welcome and Attendance (2 minutes):**
- Greet the students and take attendance.
2. **Review Previous Lesson (3 minutes):**
- Briefly discuss what was covered in the last lesson to establish continuity.
3. **Introduction to Today's Topic (5 minutes):**
- Explain the importance of metalwork machines in various industries.
- Present the learning objectives for the lesson.
#### **Instructional Input (20 minutes)**
1. **Types of Metalwork Machines (10 minutes):**
- **Lathe Machine:**
- Describe its functions (turning, facing, cutting, etc.).
- Show an image/video of the lathe machine in operation.
- **Milling Machine:**
- Explain its uses (milling, drilling, planning, etc.).
- Display an image/video.
- **Drill Press:**
- Outline its purpose (drilling holes in metal).
- Show an image/video.
- **Grinding Machine:**
- Describe its main uses (sharpening, grinding, and polishing).
- Present an image/video.
2. **Basic Operation of Each Machine (10 minutes):**
- Discuss the basic steps to operate each machine:
- Lathe: Mounting the workpiece, setting the tool, and making the cut.
- Milling Machine: Securing the workpiece, choosing the appropriate cutter, and feeding the workpiece.
- Drill Press: Securing the workpiece, selecting the drill bit, and drilling the holes.
- Grinding Machine: Mounting the workpiece, choosing the grinding wheel, and performing the grind.
#### **Guided Practice (15 minutes)**
1. **Safety Protocols (5 minutes):**
- Emphasize the importance of safety.
- Demonstrate how to wear and use safety gear (goggles, gloves, etc.).
- Discuss specific safety measures for each machine (e.g., keeping hands clear of moving parts, using guards, etc.).
2. **Hands-on Demonstration (10 minutes):**
- If possible, take students to a workshop and demonstrate the basic operation of each machine.
- Allow a few students to try operating the machines under strict supervision.
#### **Independent Practice/Application (10 minutes)**
- Divide students into small groups.
- Provide each group with a handout summarizing the key points of the lesson.
- Ask each group to identify the machine shown on a picture and describe its function and safety protocols.
#### **Conclusion (5 minutes)**
1. **Review Key Points:**
- Recap the different types of metalwork machines and their functions.
- Reinforce the importance of safety.
2. **Assign Homework:**
- Ask students to write a short paragraph on the importance of one of the metalwork machines discussed in class.
3. **Q&A Session:**
- Open the floor for any questions or clarifications.
#### **Assessment:**
- Observations during practice sessions.
- Participation in group activities.
- Homework assignment.
### **Follow-Up:**
- **Next Lesson Preview:**
- Announce the next topic will be on "Advanced Techniques in Metalworking."
- Encourage students to read ahead in their textbooks on this topic.
- **Feedback:**
- Collect feedback from students about the lesson to improve future instruction.
