Exemplar question and grade 3 answer: 

Evaluate the movement, protection and storage functions of the skeletal system and their impact on performance.

The skeleton assists movement by allowing movement of the body as a whole and its individual parts. The bones act as levers and also form joints that allow muscles to pull on them and produce joint movements.

The skeleton also has a function where the bones of the skeleton protect the internal organs and reduce the risk of injury on impact.

The skeleton itself is made of minerals and acts as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions.

Exemplar question and grade 5 answer: 

Evaluate the movement, protection and storage functions of the skeletal system and their impact on performance.

The skeleton assists movement by allowing movement of the body as a whole and its individual parts. The bones act as levers and also form joints that allow muscles to pull on them and produce joint movements. Muscles attached to bones around a joint via tendons to allow various movement, depending on the joint.  An example would be the biceps and triceps creating flexion and extension at the elbow (hinge) joint. The skeleton also has a function where the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. The cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs. The skeleton itself is made of minerals and acts as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions. Calcium is stored in the bones when we eat foods such as dairy products in our diet. 

Exemplar question and grade 7 answer: 

Evaluate the movement, protection and storage functions of the skeletal system and their impact on performance.

The skeleton assists movement by allowing movement of the body as a whole and its individual parts. The bones act as levers and also form joints that allow muscles to pull on them and produce joint movements. Muscles attached to bones around a joint via tendons to allow various movement, depending on the joint.  An example would be the biceps and triceps creating flexion and extension at the elbow (hinge) joint. Without movement we would be unable to move or perform any sporting actions, such running, jumping, throwing, therefore movement is vital in allow us to perform in sport.

The skeleton also has a function where the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. The cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs. Without this protection vital organs would be vulnerable to injury in sports. For example if doing a tackle in rugby without the protection of the ribs and cranium the heart, lungs and brain could be permanently injured. 

The skeleton itself is made of minerals and acts as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions. Calcium is stored in the bones when we eat foods such as dairy products in our diet. Calcium and phosphorus are stored in the bones, as they help strengthen the bones to ensure they do not break easily. This is important when considering sports performance, as some sports are contact sports, and therefore you would be at risk of injury (bones breaking) should they not have enough calcium or phosphorus in the bones.
