Explanatory notes
1
For the purpose of this unit standard units and notation in science cover the
knowledge of: Système International (SI) units, physical quantities, rearranging
equations, manipulating units, dimensional analysis, standard form, indices, and logs
and exponents.
2
Calculations include knowledge of the use of calculators, including the +, -, x, /,
square, square root, pcmrwers and reciprocal functions, and order of operations.
3
Range
standard form - rounding is appropriate to the problem given in a science/laboratory
context.
4
Glossary
derived quantity – refers to a property of a
body or
substance or
phenomenon
that has a magnitude which can be expressed as a number with a unit (e.g.
temperature) can be expressed as ºC from the base unit K.
Outcomes and evidence requirements

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
