5. Practical assessment
5.3 Paper 5
Paper 5 will be a timetabled, written paper focussing on the following higher-order experimental skills:
•
planning
•
analysis and evaluation
This examination paper will not require laboratory facilities.
It should be stressed that candidates cannot be adequately prepared for this paper without extensive
laboratory work during their course of study.
In particular, candidates cannot be taught to plan experiments effectively unless, on a number of occasions,
they are required:
•
to plan an experiment
•
to perform the experiment according to their plan
•
to evaluate what they have done.
This requires many hours of laboratory-based work, and it also requires careful supervision from teachers to
ensure that experiments are performed with due regard to safety.
Paper 5 will consist of two or more questions totalling 30 marks.
Candidates will be required to design an experimental investigation of a given problem. Such questions
will not be highly structured: candidates will be expected to answer using extended, structured writing,
illustrated with appropriate diagrams, flow charts, tables or equations.
Candidates may be asked to express a prediction in the form of a written hypothesis linking independent and
dependent variables, or in the form of a graph showing the expected outcome.
There will be activities in which candidates will be given some experimental data and will be required
to analyse, evaluate and draw conclusions from it. These questions also will not be highly structured:
candidates will be expected to decide for themselves the means that should be used to analyse, evaluate
and conclude.
Some questions on this paper may be set in areas of chemistry that are difficult to investigate experimentally
in school laboratories, either because of the cost of equipment, such as colorimeters or spectrometers,
or because of restrictions on the availability of samples and materials such as expensive chemicals or
biochemicals, or for safety reasons. No question will require knowledge of theory or equipment that
is beyond the syllabus. Information that candidates are not expected to know will be provided in the
examination paper.
