### Introduction (15 minutes)
1. **Hook (5 minutes)**:
- Begin with a simple question: “What do you think happens when you flip the switch on a light bulb?”
- Encourage students to share their thoughts on how electricity powers devices around us.
2. **Contextualization (10 minutes)**:
- Briefly explain what a circuit is: a closed path through which electricity flows.
- Introduce key components: Battery (or power source), wire (conductive pathway), switch (control), and load (like an LED).
- Highlight the significance of LEDs in technology today, such as their use in indicators and displays.

### Body of the Lesson (30 minutes)
1. **Direct Instruction (15 minutes)**:
- **Explain Components**:
- **Power Source**: Function and types (batteries and sources).
- **Conductive Materials**: Role of wires and materials that conduct electricity.
- **Load**: Discuss the LED, how it emits light when current flows through it, and the importance of polarity (+ and -).
- **Introduce Circuit Diagrams**:
- Demonstrate how to draw a simple circuit diagram including a battery, switch, and LED.
- Explain symbols used in circuit diagrams (e.g., lines for wires, a circle for a battery, triangle for LED).
2. **Engagement Activity (15 minutes)**:
- **Group Discussion**:
- Divide students into small groups and ask them to think of various everyday uses for simple circuits and LEDs.
- Each group presents their ideas to the class, followed by a brief discussion on the impact of simple circuits in technology.
---
### Assessment (15 minutes)
1. **Knowledge Check**:
- **Quiz**: Conduct a short quiz (5-10 questions) on the components of a circuit, LED functionality, and circuit symbols. Questions might include:
- What are the main components of a simple circuit?
- How does an LED work?
- Draw a simple circuit diagram including a battery, switch, and LED.
2. **Class Discussion**:
- Assess students’ understanding through questions during the whole lesson. Encourage them to explain concepts in their own words, such as the importance of completing a circuit.
3. **Exit Ticket**:
- As students leave the classroom, ask them to write down one thing they learned about circuits and one question they still have.
---
### Knowledge of and Assessed by
- **Knowledge of Basic Circuitry**: Students should demonstrate an understanding of what constitutes a simple circuit and how components interact.
- **Assessments will include**
- Participation in group activities and discussions.
- Completion of the quiz, focusing on correct identification of components and functions.
- Quality and clarity of the circuit diagram they create.
---
### Conclusion (5 minutes)
- Recap the key points of the lesson.
- Emphasize the importance of understanding simple circuits in the context of advancing technology and its relevance to their everyday lives.
- Encourage students to explore more about electronics and circuit design in future lessons.
---
### Reflection (Post-Lesson)
- Reflect on student engagement and understanding based on quiz results and participation.
- Adjust future lessons based on question trends or areas of confusion identified through assessments.
