Our staff reflection for this month gave us an opportunity to share what our experience in the ministry of Catholic education has taught us about generosity.
Aims or objectives The purpose of the experiment There may be one aim or several. For instrumentation-based practicals it is customary to mention the apparatus to be used.
For example, the aim for a biochemistry practical which uses a spectrophotometer to determine serum protein levels might be written as "to determine protein levels in normal serum samples by spectrophotometry".
Method or materials and methods How you carried out the experiment and what reagents you used Normally, the method is given out as part of the practical notes and very rarely would you be required to rewrite it, although you may have to note any alterations. Some lecturers will be happy with a reference to the method, e.
Results What you found This is the raw data and is best presented in the form of tables and graphs. Record your data in tables and use the tabulated data to do the graphs.
Record any data you have determined from the graph in a separate table. For example, if you are trying to determine protein levels by spectrophotometry, you would record all the spectrophotometry readings for your standards and samples in the first table, and use the standard readings to construct a graph of protein concentration versus absorbance readings a standard curve.
The concentration of the samples can then be worked out from the graph, and recorded in a separate table.
If the amount of raw data is excessive, consider presenting it as an appendix. Conclusion An interpretation or summary not a discussion of your results This is normally a brief statement e.
It should always reflect the question s posed in the Aim s. Sometimes the conclusion is not separate from the discussion, i. Sometimes the conclusion may be required to go after the discussion, in which case it will not be a summary of the results but will be what you conclude based on your discussion.
This type of conclusion will probably be about a paragraph in length. Discussion What the results mean, whether they were as expected and if not, why notany problems with the practical etc. For example, a result outside the normal reference range could indicate one or more disease states, which should be mentioned.
It is usual to run a positive and negative control with any analysis as a way of making sure that the method worked. This would be in the form of a normal and an abnormal control of known value for a practical like the serum protein analysis. If these controls give results within their expected ranges you can generally assume that your sample result is valid.
If not, this is a good indication that something went wrong, somewhere!
Sometimes the controls are past their expiry date, which means you have no way of knowing if your results are valid.Engineering and science writing skills; Writing lab reports; Print to PDF.
