Level: Form 3 Biology
Link to Curriculum: Form 3 Biology: Topic 2 – Human Physiology –
Sub-topic 2.4 Skeleton and muscular system
Time: Double lesson
Students should be able to:
o Describe the structure and function of the skeleton
o State the scientific names for most important bones
What to do before Audio
Ask the pupils the following questions and discuss for 5 minutes only.
(a) What do you already know about the skeleton?
(b) What would life be like without a skeleton?
(c) Do you know any animals without a skeleton – what are they like?
Now write the following on the board:
Copy the following question into your exercise books. As you listen, find the answer to this question:
What five different functions does the skeleton perform in the body?
Ask the students to listen carefully to the audio. Tell them that they may make notes as they listen if they wish and that they
should follow any instructions given on the audio. Switch on and make sure that the volume is loud enough for everyone in
the class to hear.
PLAY AUDIO PART ONE – pause the audio where you feel appropriate and recap but avoid replaying.
What to do after
Audio Part 1
1. Tell the students to write their answer to the question into their exercise books,
Don’t discuss the answers
2. When they have finished encourage to compare their answer to the question on the blackboard in pairs or in groups
3. Now discuss the answers with the students and check their understanding and also address their
1. They protect us - the cranium or skull protects the brain and the ribs protect vital organs like the heart.
2. They give shape to the body - making us tall or short.
3. They support the body - the vertebral column holds the body upright.
4. They allow movement - muscles are attached to bones, which are jointed. When the muscles contract the bones
5. And finally, they produce blood - red blood cells (to carry oxygen) and white blood cells (to protect against
infection) are produced in the bone marrow of some bones.
1. Hand out work cards on the skeleton to students and have them work in pairs or groups to complete the exercises in
their exercise books.
2. Go through the answers and discuss with the class.
Work Card Activity Two
Write the following paragraph in your exercise book. The words needed to complete it are hidden in the word search square. Can
you find them?

All the bones in your body make up the 1._________. There are 206 all together, and they come in many different shapes and
sizes. Some are round like the 2.________, some long like the 3.________ (upper arm), some flat like the scapula
(shoulder blade). Some are large like the 4._______ (thighbone) and others very small like the bones in your 5._______.
Bones are connected to each other at 6.______ by cartilage, tendons, and muscles. The knee and the 7______ are good
examples of joints. A 8.________ is someone who works with injuries of skeleton and muscles. There are five different
functions performed by the skeleton
A. Bones can protect us – e.g. the skull protects the 9______ and 10.______ protect vital organs
B. Bones give the body shape – making us tall or short
C. Bones 11.________the body – e.g the vertebral column holds the body upright
D. Bones allow movement – When 12_____ contract, they move bones.
E. The bone 13.______ in the centre of bones produces both 14_____ cells and white cells.
1. skeleton, 2. skull, 3.humerus, 4.femur, 5.ear, 6.joints, 7.elbow, 8. physiotherapist, 9.brain, 10. ribs, 11. support, 12.muscles,
13 marrow, 14 red.
Play Audio Part 2 and then ask the students to complete Activity Three
Work Card Activity Three: The Skeleton (Continued)
1. Arrange each set of 3 bones in the correct order working downwards or away from the head:
a. Sternum, vertebra, rib cage
b. humerus, radius, scapula
c. femur, patella, pelvis
d. cranium, vertebrae, pelvis
e. fibula, tibia, ankle
2. Draw and label a diagram of the skeleton that includes all the bones in question 1.
3. The largest animal without bones is the giant squid which belongs to the same family as the octopus. It is found in the
ocean. Why do you think this is so?
1a. vertebra, rib cage, sternum
b. scapula, humerus, radius
c. pelvis, femur, patella
d. cranium, vertebrae, pelvis
e. tibia, fibula, ankle
3. In the ocean buoyancy provides support so a skeleton is less necessary.
