Materials:

• Whiteboard and markers
• Projector and computer (optional)
• Examples of digital circuits containing NOT gates
• Notebooks and pens

Lesson Outline:

1. Introduction (5 minutes)
   • Begin by reviewing the concept of logic gates and their significance in digital electronics.
   • Introduce the specific logic gate being covered: the NOT gate.
   • Outline the lesson objectives.
2. Presentation on NOT Gates (15 minutes)
   • Explain the function of NOT gates: they produce a HIGH output if the input signal is LOW, and vice versa.
   • Present the truth table of a NOT gate, showing all possible input-output combinations.
   • Discuss the symbol representation of a NOT gate and its logical expression.
   • Provide real-world examples where NOT gates are used, such as in signal inversion or logical negation.
3. Interactive Activity: Truth Table Analysis (15 minutes)
   • Distribute handouts with truth tables of NOT gates.
   • Have students work in pairs to analyze the truth tables and identify patterns in the input-output relationships.
   • Discuss the findings as a class and address any questions or misconceptions.
4. Group Discussion: Applications of NOT Gates (10 minutes)
   • Divide students into small groups.
   • Assign each group a different application of NOT gates (e.g., traffic light control, binary subtraction).
   • Have groups brainstorm and discuss how NOT gates are utilized in their assigned application.
5. Conclusion and Reflection (5 minutes)
   • Summarize the key points covered in the lesson.
   • Ask students to write a short reflection on what they learned about NOT gates and how they can be applied in real-world scenarios.
   • Collect the reflections to review students' understanding and insights.

Assessment:

• Participation in group discussions and activities
• Accuracy of analysis in the interactive activity
• Quality of reflections on the applications of NOT gates

---

Homework:

• Assign students to research a specific digital circuit that utilizes NOT gates and prepare a brief report or presentation on its functionality.
• Encourage students to explore other types of logic gates and their applications in digital electronics.
