**Grade Level:** Senior Secondary 3
**Duration:** 1 Hour
**Subject:** Physical and Health Education
**Topic:** Simple Mechanics of Motion
---
**Objective:**

**Materials Needed:**
- Whiteboard and markers
- Projector (for videos and presentations)
- Stopwatch
- Measuring tape
- Various sports equipment (e.g., balls, cones, jump ropes)
- Handouts with formulas and definitions
---
**Lesson Structure:**
### Introduction (10 minutes)
1. **Greeting and Attendance:** Take attendance and ensure all students are prepared for the lesson.
2. **Warm-up Activity:**
- Light jogging or stretching to prepare muscles for activity.
- Briefly discuss the importance of warm-up in preventing injuries and improving performance.
### Theoretical Instruction (15 minutes)
1. **Introduction to Mechanics:**
- Define mechanics and its relevance to physical activities.
- Key terms: velocity, acceleration, force, inertia.
2. **Discussion:**
- **Velocity:** Rate of change of position. Formula: \( v = \frac{d}{t} \)
- Example: The speed of a sprinter on the track.
- **Acceleration:** Rate of change of velocity. Formula: \( a = \frac{\Delta v}{\Delta t} \)
- Example: A swimmer's start from the block.
- **Force:** A push or pull that causes an object to move or accelerate. Formula: \( F = m \times a \)
- Example: The force applied by a football player when kicking a ball.
- **Inertia:** The tendency of an object to resist changes in its state of motion.
- Example: How hard it is to stop a running player.
### Practical Application (20 minutes)
1. **Group Activity:**
- Divide students into small groups.
- Assign each group a simple experiment related to mechanics (e.g., measuring the time and distance of a ball rolling down a slope to calculate velocity).
- Provide necessary equipment and handouts with instructions and formulas.
- Allow groups to perform their experiments and record data.
2. **Observation and Supervision:**
- Walk around to observe and assist groups as needed.
- Ensure students are correctly applying formulas and concepts.
### Group Discussion and Analysis (10 minutes)
1. **Data Sharing:**
- Have each group share their findings with the class.
- Discuss variations in results and reasons for discrepancies.
2. **Application to Sports:**
- Discuss how understanding mechanics can improve performance in sports.
- Ask students to suggest how they might use these principles in their own physical activities.
### Conclusion and Reflection (5 minutes)
1. **Summary:**
- Recap key points discussed about the mechanics of motion.
- Highlight the relevance of these principles in everyday physical activities and professional sports.
2. **Q&A:**
- Allow time for students to ask questions or express any points of confusion.
3. **Homework Assignment:**
- Assign a brief homework task where students will identify and describe how they observe mechanics principles in a sport of their choice (one page, due next class).
### Cool Down and Wrap-Up (5 minutes)
1. **Cool-Down Exercises:**
- Lead students through some gentle stretches and breathing exercises to conclude the physical activity.
2. **Closing Remarks:**
- Thank the students for their participation and remind them of the homework assignment.
- Dismiss the class.
---
**Assessment:**
1. **Formative Assessment:**
- Observation of student participation and engagement during activities and discussions.
- Worksheets and data from experiments.
2. **Summative Assessment:**
- Graded homework assignment evaluating students' understanding and application of mechanics principles in sports.
---
**Notes:**
- Adapt the lesson based on the available resources and the specific needs of students.
- Ensure all activities adhere to safety guidelines and are supervised properly to prevent injuries.
