PLANNING
2 suggest relevant procedures to be
used and select appropriate equipment
to carry out the task.
4 design a plan in which enough relevant
factors are taken into account and controlled
in order to obtain valid data.
6 describe the observations, measurements
and precautions needed to obtain valid
quantitative data.
8 provide a reasoned explanation for
the procedures selected, describe the
anticipated method of collecting the
data and suggest how they might be analysed,
including an appropriate simple statistical
test to support or reject the hypothesis
being tested.
IMPLEMENTING
2 safely use appropriate techniques
and equipment to obtain some relevant
observations and measurements, with
units given where applicable.
4 use techniques and equipment in a
methodical and organised way to obtain
and record an adequate range of valid
observations and measurements.
6 use appropriate techniques and equipment
to make detailed observations and suitably
accurate quantitative measurements,
and record these in a clear and understandable
form.
8 take precautions to ensure the reliability
of the data obtained in relation to
the problem being investigated.
ANALYSING EVIDENCE AND DRAWING
2 carry out some processing of results,
e.g. in the form of a simple graph,
chart or diagram, and identify the main
pattern or trend.
4 process the data obtained with appropriate
graphs and calculations, describe the
relevant trends and patterns and provide
a conclusion or solution to the problem
which is consistent with the data.
6 use appropriate scientific terminology
to provide a full report of the data
obtained, analyse in detail patterns
within the data obtained and draw appropriate
conclusions.
8 make a full analysis of the outcomes
of the investigation, supporting these
with appropriate evidence from the data
and explaining conclusions in relation
to scientific knowledge.
EVALUATING EVIDENCE AND PROCEDURES
2 recognise the limitations of the apparatus
and techniques used.
4 assess the effect of the limitations
of the apparatus and techniques on the
reliability and precision of the data
obtained.
6 assess the effect of the limitations
of the apparatus, techniques and reliability
on the conclusions made.
SYNTHESIS OF PRINCIPLES AND CONCEPTS
2 select some appropriate knowledge
and principles.
4 select some knowledge and principles
and explain their relevance to the investigation.
6 select most of the relevant knowledge
and principles, provide a reasonable
explanation of their significance to
the investigation and generally present
the account clearly and logically using
appropriate scientific terminology.
8 select knowledge, principles and concepts,
all of which are relevant to the investigation,
explain their significance and apply
them to the specific situation; present
the account clearly and logically using
appropriate scientific terminology effectively
and accurately throughout.
