Examiners must mark the first candidate in exactly the same way as they mark the last. • Mark schemes should be applied positively. Candidates must be rewarded for what they have shown they can do rather than penalised for omissions. • Examiners should mark according to the mark scheme not according to their perception of where the grade boundaries may lie. • There is no ceiling on achievement. All marks on the mark scheme should be used appropriately. • All the marks on the mark scheme are designed to be awarded. Examiners should always award full marks if deserved, i.e. if the answer matches the mark scheme. Examiners should also be prepared to award zero marks if the candidate’s response is not worthy of credit according to the mark scheme. • Where some judgement is required, mark schemes will provide the principles by which marks will be awarded and exemplification may be limited. • When examiners are in doubt regarding the application of the mark scheme to a candidate’s response, the team leader must be consulted. • Crossed out work should be marked UNLESS the candidate has replaced it with an alternative response. Mark schemes have been developed so that the rubrics of each mark scheme reflects the characteristics of the skills within the AO being targeted and the requirements of the command word. So for example the command word ‘Explain’ requires an identification of a point and then reasoning/justification of the point. Explain questions can be asked across all AOs. The distinction comes whether the identification is via a judgment made to reach a conclusion, or, making a point through application of knowledge to reason/justify the point made through application of understanding. It is the combination and linkage of the marking points that is needed to gain full marks. When marking questions with a ‘describe’ or ‘explain’ command word, the detailed marking guidance below should be consulted to ensure consistency of marking. Assessment Objective Command Word Strand Element Describe Explain AO1* An answer that combines the marking points to provide a logical description An explanation that links identification of a point with reasoning/justification(s) as required AO2 An answer that combines the marking points to provide a logical description, showing application of knowledge and understanding An explanation that links identification of a point (by applying knowledge) with reasoning/justification (application of understanding) AO3 1a and 1b An answer that combines points of interpretation/evaluation to provide a logical description AO3 2a and 2b An explanation that combines identification via a judgment to reach a conclusion via justification/reasoning AO3 3a An answer that combines the marking points to provide a logical description of the plan/method/experiment AO3 3b An explanation that combines identifying an improvement of the experimental procedure with a linked justification/reasoning Paper 2PF 2206 Question number Answer Additional guidance Mark 1 (a) 1 mark for each correct line. more than one line to or from any box loses the mark for that symbol. (3) AO1 Question number Answer Additional guidance Mark 1 (b)(i) B electrons A C and D are incorrect because they do not move through a conductor to create an electric current. (1) AO1 Question number Answer Additional guidance Mark 1 (b)(ii) substitution (1) (charge =) 0.21 x 300 (3) AO2 AO1 evaluation (1) (charge = ) 63 award full marks for the correct answer without working unit (1) coulombs independent mark C(oulombs) c As Total 7 marks Question number Answer Additional guidance Mark 2 (a)(i) (soft) iron (1) allow (in this context) nickel (alloys) cobalt steel (1) AO1 Question number Answer Additional guidance Mark 2 (a)(ii) would be magnetised (when switch is closed) (1) would be demagnetised when switch is open (1) (is) magnetic (is) electromagnetic induced magnetism magnetism can be switched off accept for either mark not permanent magnet or temporary magnet (2) AO1 Question number Answer Additional guidance Mark 2 (b)(i) the Earth/world/planet has a magnetic field / core(1) Earth/world/planet has a north (and south) pole (1) AO3 Question number Answer Additional guidance Mark 2(b)(ii) direction (of the field) has changed / rotated (1) (strength of the) field has increased (1) (from 0 to) 36o from N to NE field is stronger (changed by) 16.52 (μT) numbers have increased (from 46.67 to 63.19) (2) AO3 Question number Answer Additional guidance Mark 2 (b)(iii) a description including three from use of equipment to measure distance (1) ruler / tape measure obtain a measurement (1) measure / record strength of the field (at a certain point) measure the distance between phone and magnet (3) A03 change the conditions (1) move the phone / magnet (to a different location) rotate the phone/magnet process the results (1) e.g. • draw a diagram • make a table • compare results/values • see when (field) stays constant Total 9 marks Question number Answer Additional guidance Mark 3 (a) (i) B live and neutral A , C and D are incorrect because the terms positive and negative are not used in the context of wires in a mains cable. (1) AO1 Question number Answer Additional guidance Mark 3 (a)(ii) a description that incudes any two from melts (1) if there is a fault (1) breaks the circuit (1) stops current (1) safety (1) blows / breaks if current too large prevents overheating / fire (2) AO1 if no other marks scored allow 1 mark for identifying the fuse.
