Main Content (35 minutes)
Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: Exam Tip, You must know all five functions, The vertebral column.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.

Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: the skeletal system. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Physical Education because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.

First Look
Start with the revision notes summary, then attempt: Name the five functions of the skeleton.

Your student states one thing they learned and one question they still have about the skeletal system.
Lesson 2: Core Concepts: the skeletal system
Duration: 50 minutes
Starter Activity (5 minutes)
Review Previous Lesson
Quick recap: write 3 key points from Lesson 1 on the skeletal system. Check them against the notes below.
Main Content (35 minutes)
Key Fact: The adult human skeleton is made up of 206 bones . At birth, humans have around 270 bones, but many fuse together as the body grows.
Exam Tip: The pectoral girdle (shoulder) and pelvic girdle (hip) are part of the appendicular skeleton, not the axial. A common mistake is thinking the pelvis belongs to the axial skeleton because it's in the centre of the body.
You must know all five functions: Support, Protection, Movement, Mineral Storage, Blood Cell Production.
The vertebral column: consists of 33 vertebrae stacked on top of each other, separated by intervertebral discs that act as shock absorbers.
Long bone structure: A long bone has an outer layer of compact bone (dense and strong) and an inner layer of spongy bone (light and shock-absorbing). The shaft is called the diaphysis and the ends are called epiphyses .
PE Exam Tips — The Skeletal System: 1. For The Skeletal System questions, use subject-specific terminology precisely 2. Support every point with specific evidence or examples 3. Show balanced analysis — consider different perspectives before reaching a conclusion 4. Link your understanding of The Skeletal System to real-world contexts where possible 5. For longer answers, plan your response to address all parts of the question
| Term | Meaning | Example |
|---|---|---|
| Number of bones | 80 | 126 |
| Location | Central axis of the body | Limbs and limb attachments |
| Key bones | Skull, vertebral column, ribcage, sternum | Arms, legs, pectoral girdle, pelvic girdle |
| Primary function | Protection of vital organs, support of upright posture | Movement and locomotion |
| Examples | Cranium (8 bones), vertebrae (33), ribs (24), sternum (1) | Humerus, radius, ulna, femur, tibia, fibula, scapula, clavicle, pelvis |
| Long | Longer than they are wide; shaft with two ends | Act as levers for movement; contain red marrow in ends |
| Short | Roughly cube-shaped; spongy inside | Provide stability and some movement; absorb shock |
| Flat | Thin, flattened and often curved | Protection of organs; large area for muscle attachment |
Practice (10 minutes)
Q: Name the five functions of the skeleton.
Answer: Support, protection, movement, mineral storage, blood cell production.

Explain Back
Your student teaches the key points back to you without looking. Fill any gaps immediately.
Lesson 3: Application: the skeletal system
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
Recall the key terms: Exam Tip, You must know all five functions, The vertebral column. Define each in one sentence.
Main Content (35 minutes)
Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.
Q1: Name the five functions of the skeleton.
Answer: Support, protection, movement, mineral storage, blood cell production.
Q2: How many bones make up the axial skeleton?
Answer: 80 bones make up the axial skeleton.
Q3: Give one example each of a long bone, a short bone, a flat bone and an irregular bone.
Answer: Long: femur; Short: carpals; Flat: cranium; Irregular: vertebrae.
Q4: Explain why the vertebral column is classified as irregular bones.
Answer: Vertebrae have complex, irregular shapes that do not fit into the long, short, or flat categories. Each vertebra has a body, spinous process, transverse processes and a vertebral foramen, making their shape irregular.
Q5: Which part of the vertebral column supports the most body weight, and why?
Answer: The lumbar region (5 vertebrae) supports the most body weight because it bears the entire weight of the upper body and transfers it to the pelvis and legs.
Q6: Describe how the skeleton supports blood cell production.
Answer: Red bone marrow, found in the sternum, ribs, pelvis, vertebrae and the ends of long bones, produces red blood cells (carry oxygen), white blood cells (fight infection) and platelets (help blood clot).

Error Review
Review any questions answered incorrectly. Identify whether the error was knowledge, method, or reading the question.
Lesson 4: Exam Practice: the skeletal system
Duration: 50 minutes
Starter Activity (5 minutes)
Command Words
Review what these command words require: state (one point), describe (say what happens), explain (say why), compare (both sides), evaluate (judgement).
Main Content (35 minutes)
Exam-Style Question
Attempt a past-paper style question on the skeletal system from the exam board past paper finder (see Resources), then mark it against the scheme.
Exam Tips: Always use the correct scientific names for bones (e.g. femur, not "thigh bone") | Link bone classification to function - examiners want to see you understand WHY a bone is shaped that way | The mnemonic "Breakfast at 7, Lunch at 12, Dinner at 5" helps remember cervical/thoracic/lumbar vertebrae counts | When asked about functions, state all five - don't just list two or three | Know the difference between axial (80) and appendicular (126) skeleton bone counts | Be ready to explain how bone shape relates to function in sporting contexts
Common Errors: Watch Out! Students often confuse the pelvis as part of the axial skeleton because it is in the centre. Wrong: "The pelvis is part of the axial skeleton." Correct: "The pelvis is part of the appendicular skeleton." Students often forget mineral storage and blood cell production as functions. Wrong: "The skeleton has three functions: support, protection and movement." Correct: "The skeleton has five functions: support, protection, movement, mineral storage and blood cell production." Students often confuse short bones with small bones. Phalanges are small but classified as long bones. Wrong: "Phalanges are short bones because they are small." Correct: "Phalanges are long bones - their length
Stretch & Challenge (Grade 8-9):
- Synoptic links: explain how the skeletal system connects to another Physical Education topic you have studied
- Real-world: research one real-world use or example of the skeletal system
- Critical: "What are the limitations of the models used in the skeletal system?"
