2. Sewing machine manuals
3. Spools of thread
4. Bobbins
5. Sewing machine needles
6. Fabric scraps
7. Small scissors or thread clippers
8. Safety pins
**Introduction (10 minutes):**
1. Greet students and briefly review the previous class on basic sewing machine knowledge.
2. Explain the importance of mastering the sewing machine in textile and clothing projects.
3. Introduce today’s objectives and outline the lesson structure.
**Lesson Structure:**
**Part 1: Identifying Machine Parts (15 minutes)**
1. Distribute sewing machine manuals to students.
2. Demonstrate by pointing out each part of the sewing machine: spool pin, bobbin winder, needle, presser foot, stitch selector, handwheel, foot pedal, etc.
3. Allow students to come forward in groups to identify parts on an actual machine.
**Activity:**
- Divide students into small groups and provide each group with a printed diagram of a sewing machine.
- Have students label each part on the diagram and discuss their functions.
**Part 2: Threading the Machine and Winding the Bobbin (15 minutes)**
1. Demonstrate how to thread the sewing machine, including threading the upper thread and winding and inserting the bobbin.
2. Emphasize the importance of following the manual instructions and ensure that the thread moves smoothly without tangles.
**Activity:**
- Allow students to practice threading the sewing machine and winding the bobbin. Move around to assist and correct as needed.
**Part 3: Basic Machine Maintenance (10 minutes)**
1. Explain the significance of regular machine maintenance to avoid malfunctions and prolong the machine’s life.
2. Demonstrate basic maintenance steps: cleaning the machine, oiling moving parts, changing the needle, checking tension.
**Activity:**
- In groups, have students perform a simple maintenance check on their sewing machines under supervision.
**Part 4: Safe Operation of the Sewing Machine (10 minutes)**
1. Review safety considerations: proper seating, using the foot pedal, keeping fingers away from the needle, unplugging the machine when not in use.
2. Demonstrate simple sewing exercises: straight stitch and basic backstitch.
**Activity:**
- Allow students to practice sewing straight lines and curves on fabric scraps, focusing on maintaining control and following safety protocols.
**Conclusion (5 minutes):**
1. Recap the key points of the lesson: parts of the sewing machine, threading, maintenance, and safe operation.
2. Answer any remaining questions.
3. Assign homework: Have students research different types of sewing machines (mechanical, electronic, computerized) and write a short summary of their features and differences.
**Assessment:**
- Observe student participation during activities.
- Check accuracy and completeness of labeled diagrams.
- Evaluate students’ ability to thread and maintain the sewing machine.
- Monitor safe and efficient operation of the sewing machine during practice sessions.
By the end of this lesson, students should be more confident in handling and operating a sewing machine, an essential skill in clothing and textile production.
