SCIENCE 1113/02
Paper 2

FINAL MARK SCHEME October 2021


Maximum Mark: 50


Published
This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the
examination. It shows the basis on which Markers were instructed to award marks. It does not indicate the
details of the discussions that took place at the Markers’ meeting before marking began, which would have
considered the acceptability of alternative answers.

Mark schemes should be read in conjunction with the question paper and the End of Series Report.
Cambridge will not enter into discussions about these mark schemes.

General guidelines on marking

Many descriptive answers can be expressed in a variety of ways. Professional judgement
can be used in these cases, providing it matches the marking points and further information
in the mark scheme.

Answers may have words spelt incorrectly. Credit is normally given for phonetically correct
answers, unless the word has a scientifically different meaning. For example, where the answer
should be antennae, credit will be given for antena but not for anthen (too close to anther).

Only the science is being assessed so answers do not need to be grammatically correct.
Significant figures will be indicated in the question or in the mark scheme.

Unless specified all marking points are independent.


Annotations and abbreviations

/ or alternate responses for the same marking point

( ) brackets the words or units in brackets do not need to be stated, for example,
(recycles or releases or provides) minerals = minerals scores the mark

underline exact word is required

Accept an acceptable response

Do not accept indicates an incorrect response that would contradict another otherwise
correct alternative

Ignore indicates an irrelevant answer that is not creditworthy. Full marks can
still be achieved even with answers that are ignored.

Note provides extra information when necessary

ecf error carried forward; marks are awarded if an incorrect response has been
carried forward from earlier working, provided the subsequent working is
correct

ora or reverse argument; for example, as mass increases, volume increases
could be written as mass decreases, volume decreases
