  1. INDIVIDUAL INVESTIGATIONS How to write up your investigation report

  2. THE INVESTIGATION REPORT • You write it • Your teacher marks it • It is sent away to a moderator who will check that the marks are appropriate

  3. MARKING CRITERIA • You can read them in the specification • There are four EQUAL sections • Make sure that you take notice of the detail

  4. MARKING CRITERIA • Planning • Implementing • Analysing • Evaluating

  5. MARKING CRITERIA HAVE TWO STRANDS • Planning • Experimental detail • Background theory

  6. MARKING CRITERIA HAVE TWO STRANDS • Implementing • Doing • Recording

  7. MARKING CRITERIA HAVE TWO STRANDS • Analysing • Graphs and calculations • Drawing conclusions

  8. MARKING CRITERIA HAVE TWO STRANDS • Evaluating • Limitations of methods • Uncertainty associated with measurements

  9. MARKING CRITERIA 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

  10. PLANNING – 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).

  11. PLANNING – 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

  12. PLANNING – YET MORE DETAIL • 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

  13. EXAMPLE OF A SYNOPTIC GRID

  14. RECORDING 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

  15. REPEATING 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

  16. ANALYSING - CALCULATIONS • Show ALL of your calculations • EXPLAIN all of your calculations

  17. ANALYSING - 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

  18. ANALYSING - CONCLUSIONS • 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

  19. EVALUATING • 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

  20. EVALUATING – THE DETAIL • Calculate the uncertainties associated with ALL types of your measurements • Identify the limitations of your experimental procedures

  21. EVALUATING – MORE DETAIL • Comment on the relative significance of limitations and uncertainties • Use the above to explain what and why you would do differently if you repeated the investigation • Don’t skimp
