Lesson Plan for Junior Secondary 3 - Basic Tech - Simple Electrical Wiring I

### Lesson Plan: Simple Electrical Wiring **Grade Level:** Junior Secondary 3 **Subject:** Basic Tech **Lesson Duration:** 90 minutes **Topic:** Simple Electrical Wiring **Lesson Objectives:** By the end of the lesson, students should be able to: 1. Understand the basic components involved in simple electrical wiring. 2. Identify and describe the function of each component in an electrical circuit. 3. Safely wire a basic electrical circuit involving a switch, a light bulb, and a power source. 4. Demonstrate an understanding of basic safety precautions when handling electrical circuits. **Materials Needed:** - Breadboard (optional) - Batteries (AA or 9V) - Light bulbs (low voltage, appropriate for the battery) - Light bulb holders - Switches - Connecting wires - Wire strippers - Insulated gloves - Safety goggles - Diagram handouts of basic electrical circuits - Whiteboard and markers - Computer and projector (for presentations) **Lesson Outline:** **Introduction (15 minutes):** 1. **Greeting and Attendance (2-3 minutes):** - Teacher takes attendance and greets students. 2. **Engage (5 minutes):** - Start with a brief discussion about where students see electrical wiring in daily life (e.g., home lighting, electronics). 3. **Objective Introduction (5 minutes):** - Outline the day's objectives and activities. 4. **Brief Safety Talk (2 minutes):** - Emphasize the importance of safety when dealing with electrical components. **Direct Instruction (30 minutes):** 1. **Basic Concepts and Components (15 minutes):** - Use a projector to display diagrams of a simple electrical circuit. - Explain the basic components: power source (battery), conductor (wires), load (light bulb), and control mechanism (switch). - Discuss the function of each component. 2. **Demonstrate Wiring a Simple Circuit (15 minutes):** - Demonstrate how to wire a simple circuit: connect the battery, light bulb, and switch. - Show proper handling and connection techniques. - Highlight the importance of connecting wires to the correct terminals and ensuring good contact. **Guided Practice (25 minutes):** 1. **Hands-On Activity (15 minutes):** - Divide students into small groups. - Provide each group with materials to build their own simple circuit. - Walk around the class, providing assistance and ensuring students are following safety protocols. 2. **Checking for Understanding (10 minutes):** - Ask each group to demonstrate their circuit and explain the flow of electricity. - Provide corrective feedback where necessary. **Independent Practice (10 minutes):** 1. **Worksheet Completion (10 minutes):** - Provide students with a worksheet that includes questions about the components and process of wiring a simple circuit. - Students work independently to complete the worksheet. **Wrap-Up (10 minutes):** 1. **Review Key Points (5 minutes):** - Go over key points from the lesson. - Address any lingering questions the students may have. 2. **Summarize and Assign Homework (3 minutes):** - Summarize the activity and the learning objectives. - Assign homework: students draw and label a diagram of a simple circuit with explanations for each component. 3. **Closing Remarks (2 minutes):** - Thank students for their participation and remind them about the next class topic. **Assessment:** - Formative assessment through observation during the hands-on activity. - Summative assessment through the worksheet and assigned homework. **Extensions:** For students who grasp the basics quickly, provide additional components like resistors or buzzers to integrate into their circuits for exploration and learning more complex wiring concepts. --- This lesson plan incorporates hands-on activities to engage students and helps them understand the practical application of basic electrical wiring. Ensure safety is prioritized throughout the session.
