### Direct Instruction (20 minutes)
1. **Basic Concepts:**
- **Electricity:**
- Define electricity and differentiate between current and voltage.
- **Circuits:**
- Explain what an electronic circuit is.
- Discuss series and parallel circuits briefly.
2. **Electronic Components:**
- **Resistors:**
- Show a physical resistor and its symbol.
- Explain its function (limits current).
- **Capacitors:**
- Show a physical capacitor and its symbol.
- Explain its function (stores electrical energy).
- **Diodes:**
- Show a physical diode and its symbol.
- Explain its function (allows current to flow in one direction).
### Guided Practice (20 minutes)
1. **Hands-On Component Identification:**
- Provide each student or group with a set of physical components.
- Ask them to match real components with their corresponding symbols on a handout.
- Walk around to assist and ensure they correctly identify components.
2. **Simple Circuit Construction:**
- Demonstrate how to build a simple circuit using a breadboard, LEDs, and batteries.
- Explain the process of placing components and connecting them properly.
### Independent Practice (20 minutes)
1. **Student Activity:**
- Provide students with a simple circuit diagram (e.g., an LED circuit with a resistor and battery).
- Have students build their circuit on a breadboard following the diagram.
2. **Monitoring and Assistance:**
- Walk around the classroom, providing guidance and answering questions.
- Ensure that students connect components correctly and that circuits function as intended.
### Assessment (15 minutes)
1. **Q&A Session:**
- Ask the students questions about what they learned, such as naming components, explaining their functions, and the steps to create a circuit.
2. **Practical Test:**
- Have students demonstrate their simple circuits to ensure they meet the project requirements.
### Conclusion (10 minutes)
1. **Review:**
- Summarize the key points of the lesson.
- Emphasize the importance and applications of basic electronics.
2. **Homework Assignment:**
- Assign a worksheet with questions about electronic components and simple circuits.
3. **Preview Next Lesson:**
- Give a brief overview of what will be covered in the next lesson (e.g., basic electronic testing tools, more complex circuits).
### Closing:
- Thank the students for their participation.
- Encourage them to read more about electronics to ignite further interest in the subject.
