THE INVESTIGATION THE INVESTIGATION REPORTREPORT
You write it
Your teacher marks it
It is sent away to a moderator who will check that the marks are appropriate
MARKING CRITERIAMARKING CRITERIA
You can read them in the specification
There are four EQUAL sections
Make sure that you take notice of the detail
MARKING CRITERIAMARKING CRITERIA HAVE TWO STRANDS HAVE TWO STRANDS
Planning
Experimental detail
Background theory
MARKING CRITERIAMARKING CRITERIA HAVE TWO STRANDS HAVE TWO STRANDS
Analysing
Graphs and calculations
Drawing conclusions

Evaluating
Limitations of methods
Uncertainty associated with measurements
MARKING CRITERIAMARKING CRITERIA DESCRIPTORS DESCRIPTORS
Descriptors at levels 2, 5, 8 and 11
You need to satisfy low ones before getting access to higher marks
You have to satisfy descriptors in BOTH strands to move your mark up
PLANNING – THE DETAILPLANNING – THE DETAIL Start off with a clear aim (Don’t use a hypothesis)
Include comprehensive RELEVANT background theory
Include FULL details of the plan (e.g. preliminary experiments, modifications, how much you measured out, what you measured it with).
PLANNING – MORE DETAILPLANNING – MORE DETAIL
Explain why your choices of equipment and readings will produce useful data
Include a risk assessment which is detailed and relevant to what you are doing
PLANNING – YET MORE PLANNING – YET MORE DETAILDETAIL
Include a set of references ( include page number and links references to where you have made use of them in the text)
Include synoptic grid
Sub-headings can be helpful

RECORDING RESULTSRECORDING RESULTS
Record all measurements, not just averages
Use correct format including units as you did for AS coursework
Use helpful headings to explain what is going on
REPEATING EXPERIMENTSREPEATING EXPERIMENTS
If experiments produce poor quality data then modify and repeat them
– e.g. low titres from titrations
Gas volume measurements that are all similar
ANALYSING - ANALYSING - CALCULATIONSCALCULATIONS
Show ALL of your calculations
EXPLAIN all of your calculations
ANALYSING - GRAPHSANALYSING - GRAPHS
Make sure that your graphs are of a suitable type (NO bar charts)
Make sure your graphs are well presented (computer generated graphs can be too small and produce thick and inappropriately drawn lines)
Include a helpful title and label axes fully
ANALYSING - ANALYSING - CONCLUSIONSCONCLUSIONS
Concentrate on the detail
Try to link with the background theory in your plan
It should be a commentary on your results, not simply a description of them
Don’t skimp
EVALUATINGEVALUATING
This section carries the same number of marks as your plan.
Spend enough time on it.
This is where you can really make a difference
EVALUATING – THE DETAILEVALUATING – THE DETAIL
Calculate the uncertainties associated with ALL types of your measurements
Identify the limitations of your experimental procedures
