Lesson Plan: Auto Mechanical - Wheels and Tires II
Senior Secondary 1
Duration: 90 minutes
**Objective:**
By the end of the lesson, students will:
1. Understand the different types of wheels and tires.
2. Recognize the components and structure of wheels and tires.
3. Comprehend the importance of tire maintenance and safety.
4. Perform basic tire inspection and maintenance procedures.
**Materials Needed:**
- Whiteboard and markers
- Projector and computer
- Sample wheels and tires
- Tire pressure gauge
- Tread depth gauge
- Video clips on tire manufacturing and maintenance
- Worksheets and handouts
**Lesson Outline:**
**1. Introduction (10 minutes)**
- Greet students and take attendance.
- Briefly recap the previous lesson on Wheels and Tires I.
- Introduce the topic: Wheels and Tires II.
- Outline the objectives for the lesson.
**2. Types of Wheels and Tires (20 minutes)**
- Explain the different types of wheels: steel, alloy, and wire-spoked.
- Discuss the different types of tires: summer, winter, all-season, and performance tires.
- Show images and physical samples of different wheel and tire types.
- Use video clips to illustrate how different tires are manufactured.
**3. Components and Structure of Wheels and Tires (20 minutes)**
- Describe the key components of a wheel: rim, hub, spokes, and wheel disk.
- Explain the anatomy of a tire: tread, sidewall, beads, belts, and ply.
- Discuss the importance of tire treads and their patterns.
- Use diagrams and physical examples to highlight components.
**4. Importance of Tire Maintenance and Safety (15 minutes)**
- Discuss the importance of maintaining correct tire pressure.
- Explain the impact of tire wear and the significance of tread depth.
- Emphasize the importance of regular tire rotation and wheel alignment.
- Highlight the dangers of driving on under-inflated, over-inflated, or worn-out tires.
**5. Practical Demonstration: Tire Inspection and Maintenance (20 minutes)**
- Demonstrate how to use a tire pressure gauge to check tire pressure.
- Show students how to measure tire tread depth with a tread depth gauge.
- Perform a visual inspection of a tire to identify potential issues (e.g., cracks, bulges, embedded objects).
- Allow students to practice these procedures under supervision.
**6. Q&A and Closure (5 minutes)**
- Open the floor for questions and clarifications.
- Summarize the key points of the lesson.
- Assign homework: Have students write a brief report on the importance of tire maintenance and share their findings in the next class.
- Provide a preview of the next lesson: Advanced Tire Technology.
**Assessment:**
- Observe student participation and engagement during the lesson and practical demonstration.
- Review the students' homework reports on tire maintenance.
**Homework/Extension:**
- Students will research and write a brief report (1-2 pages) on the importance of tire maintenance. They should include tips for keeping tires in good condition and explain the potential consequences of neglecting tire maintenance. These reports will be shared in the next class.
**Reflection:**
- After the lesson, reflect on what went well and what could be improved for future lessons.
- Consider student feedback and any challenges faced during the lesson.
