Instructions for preparing apparatus

The apparatus required for each question is set out on pages 3 and 4. Enough apparatus
must be provided to ensure that

(a) _ no candidate is kept waiting at the end of the allocated time for each question,

(b) spare apparatus is immediately available in the event of failure or breakage of any
item.

It is assumed that ordinary apparatus of a Physics laboratory will be available.
Instructions for the Practical Physics Supervisor
These instructions are enough for the Supervisor to make the right decisions.

Candidates should be informed that if they find themselves in real difficulty they may ask
the Supervisor for practical assistance but that the extent of this assistance will be reported
to the Examiner who may make a deduction of marks.

The Supervisor should complete the information required on page 7 and 8 of these
instructions and enclose those pages in the envelope containing the answers of the
candidates. A note of any help given to or any particular difficulties experienced by a
candidate should also be enclosed, especially if the Examiner would be unable to discover
these from the written answers.

Should the Supervisor decide to improvise some or part of the apparatus, he/she must ensure
that this does not make the examination more or less accessible to the candidates. The
Supervisor should give details to the examiner if the apparatus used differ(s) in any
significant way from that specified in these Instructions.

It is assumed that candidates will provide themselves with such standard items as a 30 cm
tule, a pair of compasses, 0° to 180° protractor and set squares. Squared paper should be
available.

Whenever a stopwatch or stop clock is specified, candidates should be advised in advance
that they may, if they wish, use quartz wristwatches with stopwatch facilities.

It is assumed that the number of sets of apparatus for any one experiment will be at least
half the number of candidates. Where necessary, Supervisors should direct candidates as to
which experiments they are to perform first. The experiments carry the same mark value.

The supervisor MUST perform the experiments and submit with the candidates’
answers a sample set of results in the same form as that expected of the candidates.
