Lesson Plan for Senior Secondary 1 - Auto Mechanical - Braking System Iii

# Senior Secondary 1 Auto Mechanical Lesson Plan: Braking System III ## Lesson Overview **Grade Level:** Senior Secondary 1 **Subject:** Auto Mechanical **Topic:** Braking System III **Duration:** 80 minutes ### Objectives By the end of this lesson, students will be able to: 1. Explain the different types of modern braking systems. 2. Identify the components of an Anti-lock Braking System (ABS). 3. Describe the working principles of an ABS. 4. Understand the maintenance and troubleshooting of modern braking systems. ### Materials Required - Whiteboard and markers - Projector and computer - Diagrams and models of braking systems - ABS demonstration kit - Handouts on braking systems - Tools for practical demonstration (spanners, jacks, etc.) ### Lesson Structure #### Introduction (10 minutes) 1. **Welcome and Attendance:** Briefly take attendance and welcome students. 2. **Recap:** Quickly revisit the previous lessons on basic braking systems. - **Question:** "Who can tell us what we learned about traditional braking systems?" 3. **Objective Introduction:** Briefly outline what students will learn in today's lesson. #### Instructional Input (20 minutes) 1. **Types of Modern Braking Systems:** Explain different modern braking systems such as disc brakes, drum brakes, and ABS. 2. **Diagram Explanation:** Use projections of diagrams to clarify the components and working of ABS. - **Key Components:** Present the ABS module, wheel speed sensors, electronic control unit (ECU), and hydraulic valves. #### Demonstration (20 minutes) 1. **ABS Demo Kit:** Show the actual working of an ABS system with the demo kit. 2. **Hands-On Display:** Allow students to inspect the components of the demo kit. - **Explaining Function:** Describe how the sensors detect skidding/stopping and how the ECU processes this information to modulate brake pressure. #### Practice Activity (15 minutes) 1. **Group Activity:** Divide students into small groups and distribute handouts with different scenarios of ABS failures. - **Troubleshooting Exercises:** Ask them to diagnose the problems and identify possible solutions. - **Supervision and Guidance:** Walk around to assist where needed. #### Discussion and Q&A (10 minutes) 1. **Review Troubleshooting:** Discuss the scenarios and solutions as a class. 2. **Questions:** Open the floor for any questions about the day's lesson. - **Prompt Discussion:** "How do you think ABS improves vehicle safety? Can you think of any limitations?" #### Conclusion (5 minutes) 1. **Summary:** Summarize key points learned in the lesson about ABS and other modern braking systems. 2. **Homework Assignment:** Assign a reflective essay on the importance of braking system technology in modern vehicles. 3. **Next Class Preview:** Briefly mention what the next class will cover to keep students interested. - **Topic Teaser:** "Next class, we'll explore electronic stability control systems and how they work in conjunction with ABS." ### Assessment - **Formative:** Observe student participation during the group activity and demonstration. - **Summative:** Review student performance on the troubleshooting exercises and the submitted reflective essays. ### Teacher's Reflection - **After Lesson Review:** Reflect on what went well and what could be improved for future lessons. Assess whether the students met the learning objectives and adjust as needed. ### Additional Notes - **Safety Precautions:** Emphasize the importance of safety while handling tools and demo kits. - **Cultural Relevance:** Make sure examples are appropriate and relatable to students’ experiences and environments.
