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.
