Lesson Plan for Junior Secondary 3 - Basic Tech - Basic Electronics Ii

## Lesson Plan: Basic Tech for Junior Secondary 3 ### Topic: Basic Electronics II #### Duration: 60 minutes ### Objectives: By the end of this lesson, students will be able to: 1. Understand and identify basic electronic components. 2. Explain the functions of basic electronic components. 3. Assemble a simple electronic circuit using basic components. 4. Understand safety precautions when working with electronics. ### Materials Needed: - Whiteboard and markers - Projector and laptop (for PowerPoint presentation) - Basic electronic components (resistors, capacitors, diodes, LEDs, transistors, batteries) - Simple circuit kits or breadboards - Multimeters - Safety glasses and gloves ### Procedure: #### Introduction (10 minutes) 1. **Greeting and Attendance** (2 mins) - Greet students and take attendance. 2. **Review of Previous Lesson** (3 mins) - Briefly review Basic Electronics I, focusing on what was learned about electricity, circuits, and conductivity. 3. **Introduction to Today's Topic** (5 mins) - Introduce the day's topic: Basic Electronics II. - Explain the importance of understanding basic electronic components for future studies and potential careers in technology and engineering. #### Instruction (30 minutes) 1. **Presentation on Basic Electronic Components** (15 mins) - Use a PowerPoint presentation to explain the following components: - **Resistors:** Define their purpose (to limit current) and show examples. - **Capacitors:** Explain their function (to store and release electrical energy) and show examples. - **Diodes:** Clarify their role (to allow current to flow in one direction only) and show examples. - **LEDs:** Define Light Emitting Diodes and their use in indicating power supply. - **Transistors:** Explain their role in amplification and switching. - Show real-life examples and explain how each component is represented in circuit diagrams. 2. **Hands-On Activity: Assembling a Basic Circuit** (15 mins) - **Demonstration:** - Gather students around a table to watch the assembly of a simple circuit (e.g., a blinking LED circuit). - Explain each step while constructing it. - **Guided Practice:** - Distribute circuit kits or breadboards and components to students. - Guide them step-by-step to assemble a basic LED circuit. - Ensure each student understands the connection and function of each component. #### Practice/Assessment (15 minutes) 1. **Safety Precautions** (5 mins) - Discuss safety rules for working with electronics, stressing the importance of wearing safety glasses, checking for correct voltage, and ensuring proper handling of components. 2. **Assessing Understanding: Quiz** (10 mins) - Conduct a short quiz with questions like: - What is the function of a resistor? - How does a capacitor work? - What is the purpose of a diode in a circuit? - How do you identify the positive and negative terminals of an LED? #### Conclusion (5 minutes) 1. **Summary** (3 mins) - Summarize the key points discussed. - Reiterate the importance of each component and how they work together in a circuit. 2. **Q&A Session** (2 mins) - Answer any remaining questions from students. 3. **Preview of Next Lesson** (1 min) - Provide a brief overview of what will be covered in the next lesson (e.g., more complex circuits, introduction to integrated circuits). #### Homework - Assign a short research project: Have students find a simple electronic circuit online and bring the printout to the next class. They should be prepared to explain the purpose of the circuit and the components it includes. ### Additional Notes: - Ensure that all students are actively participating and provide assistance when needed. - Monitor students for proper use of equipment and adherence to safety guidelines. - Adapt the pace of the lesson based on student understanding and engagement. ### Evaluation: - Participation during the hands-on activity. - Performance on the quiz. - Quality and understanding demonstrated in the homework assignment. By following this lesson plan, students will gain a fundamental understanding of basic electronic components, their functions, and safe handling practices.
