They will need to plan how they are going to carry out the research and collect their results for use in Part 2 and Part 3. The research can be carried out during lessons or as a homework exercise. Candidates complete Part 1 under limited control. The work of individual candidates may be informed by working with others and work may be completed out of the classroom but candidates must provide an individual response. Teachers may give generic, informal feedback while the work is being completed but may not indicate what candidates need to do to improve their work. Candidates should not be given the opportunity to redraft their work, as this is likely to require an input of specific advice. Candidates should be made aware of the time allowed for carrying out this part of the task. Candidates' access to resources is determined by those available to the centre and/or to candidates at home. The research information should be brought into the classroom. The candidate working individually should use the information to address the issues on the stimulus sheet.…show more content…
Explanation linked to experimental data and research. Detailed scientific explanation given of relationships between current, voltage, resistance, gauge and cross-sectional area, based on research and experimental data. Relationships linked to original hypothesis. Considers effects of distance and diameter on sound quality, explaining how these can be altered to result in good quality sound. * No evidence of achievement for this quality, or evidence insufficient for the award of 1 mark. © OCR 2011 SPECIMEN AO AO3 – 6 15 BLANK PAGE © OCR 2011 SPECIMEN 16 BLANK PAGE Copyright Information: Permission to reproduce items where third-party owned material protected by copyright is included has been sought and cleared where possible.
