PLANNING |
COLLECTING DATA |
| Collect secondary data including the use of
appropriate technology |
Plan practical ways to answer scientific questions and test hypotheses;
devise appropriate methods for the collection of numerical and other data |
Collect primary data including the use of appropriate technology |
| 1 - 2
|
* note of how data was collected
* some information collected and used from at least two sources
|
* hypothesis relates to the data provided but is not in a form which is testable
* outline plan includes equipment and techniques to be used plan provides a "fair test"
* no evidence of modifications of plan during the data collection phase
* plan shows limited structure with poor spelling and punctuation
|
* results recorded clearly but not in an appropriate format
|
| 3 - 4
|
* short explanation given of how data was collected with some sources listed
* relevant information collected from at least three sources;
* information presented clearly
|
* hypothesis provides a limited scientific explanation of the data provided
* plan gives sufficient detail for experiment to be repeated,
including choices of: equipment and techniques; range and
number of data points for the independent variable; number of
replicates
* some consideration given to how errors will be minimised
* no evidence of modifications of plan during the data collection phase
* plan structured clearly with occasional errors in spelling and punctuation
|
* results tabulated to include all data expected, though not in the most appropriate format
* headings given but units not always correct
|
| 5 - 6
|
* detailed explanation given of how data was collected with full bibliography
* range of sources identified and judgement used to select those appropriate to the task
* information collated and presented clearly in appropriate formats
|
* hypothesis provides a complete scientific explanation of the data provided and is capable of investigation
* comprehensive plan shows scientific understanding in making appropriate choices of: equipment and techniques; range and number of data points for the independent variable; accuracy of measurements; number of replicates
* detailed consideration given to: how errors will be minimised; variables which cannot be controlled
* where appropriate, reasoned modifications made to the plan as evidence is collected
* plan structure coherently with few, if any, errors in grammar, punctuation and spelling
|
* results tabulated clearly and logically, including use of correct headings and units
* all data expected recorded to appropriate levels of accuracy and precision

Marks | MANAGING RISK |
PROCESSING DATA |
ANALYSING AND INTERPRETING |
| Assess and manage risks
when carrying out practical |
Process primary and secondary data including the use of appropriate technology |
Analyse and interpret primary and secondary data
|
| 1 - 2
|
* limited understanding of risks in procedures with only standard laboratory safety features mentioned
* some teacher intervention required to ensure safety
|
* some evidence of processing quantitative data
* data presented as simple charts of graphs with some errors in scaling or plotting
* use of one simple mathematical technique
|
* at least one trend/pattern identified and outlined correctly
* an attempt is made to interpret the information
|
| 3 - 4
|
* some risks in procedures analysed and some specific responses suggested to reduce risks
* risks managed successfully with no significant incidents or accidents and no requirement for teacher intervention
|
* graphical and mathematical techniques used to reveal
patterns in the data
* charts or graphs used to display data in an appropriate way,
allowing some errors in scaling or plotting
* correct use of more than one simple mathematical technique
|
* main trend(s)/pattern(s) described and interpreted with
reference to quantitative data and scientific knowledge and
understanding, with some errors
* any anomalous results identified correctly and implications
discussed
|
| 5 - 6
|
* all significant risks in the plan evaluated
* reasoned judgements made to reduce risks by use of appropriate specific responses
* risks managed successfully with no incidents or accidents and no requirement for teacher intervention
|
* appropriate graphical and mathematical techniques used to
reveal patterns in the data
* type of graph, scales and axes selected and data plotted
accurately, including where appropriate a line of best fit
* correct use of complex mathematical techniques where
appropriate quantitative treatment of level of uncertainty of
data
|
* all trend(s)/patterns(s) described and interpreted correctly with
reference to quantitative data and relevant scientific
knowledge and understanding
* level of uncertainty of the evidence analysed

Marks | EVALUATING |
JUSTIFY CONCLUSION |
| Review methodology to assess fitness for purpose
|
Draw evidence-based conclusions; review hypotheses in light of outcomes
|
| 1 - 2
|
* relevant comments made about the quality of the data and the
method used
* answer is simplistic with limited use of specialist terms
3 - 4 marks
|
* conclusion given and hypothesis reviewed using the data
collected
* answers simplistic with little scientific understanding
|
| 3 - 4
|
* comments made on the quality of the data including accuracy,
linked to the method of collection
* limitations in the method of data collection identified and
suggestions for improvement given
* information is relevant and presented in a structured format
* specialist terms are for the most part used appropriately
|
* conclusion given and justified and hypothesis reviewed based
on an analysis of the data, demonstrating an understanding of
the underpinning science
|
| 5 - 6
|
* detailed and critical consideration given to the data and
methods used to obtain them
* quality of the data discussed and explained, including
repeatability and uncertainty
* limitations of the method identified and suggestions for
improvements justified
* information is relevant, clear, organised and presented in a
coherent format
* specialist terms are used appropriately
|
* conclusion given and justified and hypothesis reviewed, based
on a critical analysis of the data, and clearly linked to relevant
scientific knowledge and understanding
