Mark scheme Question Answer/Indicative content Marks Guidance 1 c. 1 Accept diagram if meaning is clear Accept any relevant practical example use BOD if the movement involves any aspect of Four marks for four from: Sub max three marks from: each movement. Accept the example for one mark if it involves the correct movement 1. (adduction) is movement towards (the midline 2 of) the body 2. Eg In swimming the propulsive/kicking of the legs during the breaststroke leg kick involves adduction 3. (abduction) is movement away from (the midline of) the body 4. Eg Box splits in gymnastics shows abduction 4 Examiner s Comments Some candidates showed confusion with this question and could not differentiate between adduction and abduction. The better candidates gave a good account and then gave a relevant practical example. Too many candidates gave examples where it was impossible to assess whether the idea of either adduction or abduction was understood, for example the breast stroke has many actions involved and is not a good example on its own of either of these movements. Candidates are advised to be more specific about the examples that they give.

4. Quads are the antagonists. 2 marks sub max for hams 5. Hamstrings will bend the knee candidates were able to explain the role of muscles in flexing the knee. Some candidates confused the actions of the two groups of muscles and some did not read the question carefully which related to flexion at the knee rather than extension. 6.

Mineral store [3] Most candidates scored at least one mark for this question. The majority of candidates could identify three different functions of the skeleton. Shape and support, protection, movement and mineral store were the most common responses. Some candidates failed to give store or storage with minerals. A number of candidates described the functions of the skeleton which is more than the command word asked for for example protect the organs (heart/lungs). One word answers in many cases were given & maximum marks could still be obtained for such lists with this identify recall question.
