### 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.
