5bSuggested answerExample B is more effective. Example A is a brief summary of the findings.It contains little or no analysis of the raw data, and no calculations orre-analyzed data.6 Primary research reports – the conclusion6aSuggested answersA research report conclusion might include:1 Suggestions about why results may not have been as expected ✔2 An explanation of your methods3 A summary of what has been learned about the theory or idea you wereresearching✔4 New data which does not appear in the main body of your study5 A statement of the value of a quantity measured ✔6 A comment about whether you met the objective of your study or not ✔7 Suggestions about future research which builds on what you havediscovered✔8 Reference to other texts9 A summary of the objective ✔6b Students compare their answers.6cSuggested answersAConclusionThe objective of this experiment was to investigate the relationship between thediameter and length of a pipe and the rate at which water flows through it. 3 Theresults suggest that the diameter of the pipe is inversely proportional to thepressure drop, while flow rate and pipe length are simply proportional to it.BConclusion5The density of water measured in this experiment was 994.936 ± 0.024 kg/m 3 .This was within the range of values in the published data. 6 The results obtained inthe experiment were accurate only to the first decimal place when compared againstpublished data. 7 A possible future experiment would ensure both that bubblesdid not enter the pipette, and readings of the water levels avoided parallax error.3It was found that the temperature of the water is inversely proportional to its density.A second variable which can affect the accuracy of water density readings was theindividual taking the reading.7 Writing a feasibility/recommendation report7a Note: Anyone struggling to remember the answers can be directed to Unit 1 Part E2,and Unit 2 Part B3.Unit 2 Part E ∙ Reporting in writing 69
