### **Lesson Outline:**
**Introduction (10 minutes)**
1. **Greeting and Attendance (2 minutes):**
- Welcome students and take attendance.
2. **Hook/Engage (3 minutes):**
- Show a short video clip or animation of the human skeletal system in movement (e.g., a joint in action or a time-lapse of bone growth).
3. **Objective Overview (2 minutes):**
- Briefly explain what students will learn: the structure, functions, and importance of the skeletal system.
4. **Pre-Assessment (3 minutes):**
- Ask a few quick questions to gauge prior knowledge (e.g., "Can anyone name the longest bone in the body?" or "What do you think the skeletal system does for us?").
**Main Instruction (30 minutes)**
1. **Lecture/Presentation (15 minutes):**
- Use the projector to display diagrams and key points.
- Cover the following topics:
- Major bones of the human body (e.g., femur, humerus, spine, skull).
- Types of bones (long, short, flat, irregular).
- Functions of the skeletal system (support, protection, movement, storage of minerals, blood cell production).
- Introduction to joints and cartilage.
2. **Interactive Activity (15 minutes):**
- **Skeleton Assembly Activity:**
- Divide the class into small groups.
- Provide each group with a mix-and-match diagram of the skeletal system.
- Task them with assembling a correct diagram using clues provided in handouts.
- Walk around and assist groups as needed.
**Discussion and Demonstration (10 minutes)**
1. **Q&A Session (5 minutes):**
- Open the floor for questions based on the assembly activity and lecture.
2. **Real-life Application (5 minutes):**
- Discuss common problems (e.g., fractures, osteoporosis) and preventive measures (e.g., diet, exercise).
**Assessment (5 minutes)**
- Conduct a quick quiz with multiple-choice and short-answer questions to assess understanding.
**Closure (5 minutes)**
1. **Recap the Lesson:**
- Summarize the main points.
- Highlight the importance of maintaining a healthy skeletal system through diet, exercise, and good posture.
2. **Homework Assignment:**
- Assign a short research project: "Choose one bone from the human body and write a one-page report on its structure, function, and any common issues it may face."
3. **Feedback and Questions:**
- Address any remaining questions.
- Provide feedback on the day's activities and performance.

### **Assessment:**
1. **Formative:**
- Monitoring group activity and participation.
- Observing responses during the Q&A session.
2. **Summative:**
- Quick quiz at the end of the lesson.
- Evaluation of the homework assignment.
---
### **Accommodations:**
- Provide visual aids and diagrams for ESL students or those with learning disabilities.
- Allow for peer assistance during group activities.
- Ensure that all materials are accessible and in multiple formats, if needed.

### **Reflection:**
After the lesson, take notes on what went well, what could be improved, and any adjustments needed for future lessons on similar topics.
