---
#### Lesson Structure:
**1. Introduction (10 minutes)**
- **Greeting and Roll Call:** Briefly greet students and take attendance.
- **Recap of Previous Lesson:** Spend a few minutes refreshing students’ memory on any previously taught concepts that will aid in the understanding of today’s topic (e.g., basic kinematics).
**2. Exploration of Concepts (20 minutes)**
- **Definition and Explanation:**
- **Position:** Define position as a point in space relative to a reference point (origin). Use Cartesian coordinates (x, y) for explanation.
- **Distance:** Explain distance as the total length of the path traveled, irrespective of direction.
- **Displacement:** Define displacement as the shortest straight-line distance from the initial to the final position, including its direction.
- **Visual Aids:**
- Use diagrams (on slides or whiteboard) to illustrate position, distance, and displacement.
- Show real-life examples (e.g., a student walking from one class to another).
**3. Practical Application (15 minutes)**
- **Solving Example Problems:**
- Walk through a few example problems on the board.
- Emphasize the step-by-step approach to differentiate and calculate distance and displacement.
**Example Problem 1:**
A student walks 3 meters east, then 4 meters north. Calculate the total distance traveled and the displacement.
**Solution:**
- **Distance:**
\( 3\, \text{meters} + 4\, \text{meters} = 7\, \text{meters} \)
- **Displacement:**
Using Pythagorean theorem:
\[ \sqrt{(3^2 + 4^2)} = \sqrt{(9 + 16)} = \sqrt{25} = 5\, \text{meters north-east} \]
- **Class Activity:**
- Distribute graph papers.
- Ask students to work in pairs and solve a given set of problems focusing on calculating distance and displacement.
**4. Group Discussion and Feedback (10 minutes)**
- **Group Discussion:**
- Allow students to share their findings.
- Discuss common errors or misconceptions.
- **Feedback Session:**
- Provide immediate feedback and corrections.
- Encourage questions and clarify doubts.
**5. Conclusion and Homework Assignment (5 minutes)**
- **Wrap-Up:**
- Summarize key points.
- Reiterate the importance of understanding the difference between distance and displacement.
- **Homework:**
- Assign a worksheet with varied problems on the topic.
**6. Assessment:**
- **Exit Ticket:**
- Ask students to write down the key difference between distance and displacement and submit it as they leave the class.
---
#### Evaluation:
- **Participation:**
- Monitor and note students’ involvement in discussions and activities.
- **Homework Review:**
- Evaluate the homework for understanding and accuracy.
- **Exit Tickets:**
- Assess the exit tickets to gauge the lesson’s effectiveness and address any remaining confusion in subsequent classes.
