Lesson Plan for Junior Secondary 1 - Basic Tech - Basic Electricity 3

### Lesson Plan: Basic Tech - Basic Electricity **Subject:** Basic Tech **Topic:** Basic Electricity **Grade Level:** Junior Secondary 1 **Duration:** 60 minutes #### Objectives: By the end of this lesson, students should be able to: 1. Understand the basic concepts of electricity. 2. Identify the basic components of an electrical circuit. 3. Construct a simple electrical circuit. 4. Explain the function of each component in a circuit. #### Materials Needed: - Whiteboard and markers - PowerPoint Presentation or visual aids (optional) - Basic circuit kits (wires, batteries, bulbs, switches) - Multimeter (optional) - Handouts on basic electricity concepts - Safety goggles #### Lesson Outline: **Introduction (10 minutes)** 1. **Greeting and Warm-Up:** - Greet students and briefly review the previous lesson. - Ask students if they have any experience with simple electronic devices and what they know about how they work. 2. **Introduction to the Topic:** - Introduce today's topic: Basic Electricity. - Explain why understanding electricity is important in everyday life. **Teaching/Demonstration (20 minutes)** 1. **Basics of Electricity:** - Define electricity as the flow of electric charge. - Explain terms like current, voltage, and resistance using simple analogies (e.g., water flow for current, water pressure for voltage). 2. **Components of an Electrical Circuit:** - Use visual aids or diagrams to explain the components: - Power source (battery) - Conductors (wires) - Load (bulb) - Switch - Provide real-life examples of these components. 3. **Simple Circuit Demonstration:** - Demonstrate building a simple circuit using a battery, wires, bulb, and switch. - Show how electricity flows from the battery to the bulb, lighting it up. - Discuss the role of each component in the circuit. **Hands-On Activity (20 minutes)** 1. **Group Activity:** - Divide students into small groups. - Distribute circuit kits to each group. - Instruct students to construct a simple circuit following the demonstrated steps. 2. **Guided Construction:** - Walk around, offering help and ensuring safety. - Encourage students to observe and note what happens when they complete the circuit and when they open the switch. **Conclusion (10 minutes)** 1. **Review of Key Concepts:** - Review the definitions of voltage, current, resistance, and the function of each circuit component. - Ask volunteers to explain how they constructed their circuits and what they observed. 2. **Q&A Session:** - Allow students to ask questions and clarify any doubts. - Encourage students to share their experiences and interesting findings from the activity. 3. **Wrap-Up and Assignment:** - Summarize the lesson. - Give students a simple assignment: Draw and label a basic circuit diagram, highlighting the path of the electric current. - Explain that in the next class, they will learn about more complex circuits and devices. **Assessment:** - Observe students during the hands-on activity for participation and understanding. - Review students' circuit diagrams and their explanations of the components. **Homework:** - Research and bring information on household electrical safety practices. - Write a short paragraph on why it is important to turn off devices when not in use. --- By following this lesson plan, students should gain a foundational understanding of basic electricity, which can be built upon in future lessons.
