About this course

Unit 1: Chemistry B – modules C1, C2, C3 (B641)
Unit 2: Chemistry B – modules C4, C5, C6 (B642)
Unit 3: Chemistry B – ‘Can Do’ tasks and report on ‘Science in the News’ (B645).
Skills assessment consists of two elements: Can-do tasks & Report on Science in the news.
Unit 4: Chemistry B Unit 4 – Research Study, Data Task and Practical Skills (B646). Candidates produce a portfolio comprising three elements: Research Study, Data Task and Practical Skills.

Candidates take Units 1 and 2 and either Unit 3 or Unit 4.

Unit 1 and 2 exams can be taken in January and/or June.
Unit 3 and 4 skills assessments are only available in June.

Different tiers can be chosen for different units.

Summary of the Elements of Unit 3 (B635)
Can-Do tasks: These are assessed and recorded throughout the course as the candidate fulfils them. The marks are recorded on the Candidate Record Card.
Report on Science in the News: Candidates are required to use stimulus material provided by OCR and other sources of information to research the way in which scientific data and ideas are dealt with by the media. The number of reports attempted is at the discretion of the Centre, but the results of only one may be submitted

Summary of the Elements of Unit 4 (B636)
Research Study: Candidates are required to use stimulus material provided by OCR and other sources of information to research scientific ideas. The number of reports attempted is at the discretion of the centre, but the results of only one may be submitted.
Data Task: Candidates are required to analyse and evaluate data and to plan further work (which will not be carried out). The number of tasks attempted is at the discretion of the centre, but the results of only one may be submitted.
