It should always reflect the question(s) posed in the Aim(s). "the concentration of protein in serum sample xyz was found to be xx g/L, which is within the normal reference range"), or it may even be a tabulated summary of results. Conclusion An interpretation or summary (not a discussion) of your results If the amount of raw data is excessive, consider presenting it as an appendix. The concentration of the samples can then be worked out from the graph, and recorded 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). Record any data you have determined from the graph in a separate table. Record your data in tables and use the tabulated data to do the graphs. This is the raw data and is best presented in the form of tables and graphs. "see practical notes page xx - alterations noted" and others may require a photocopy of the method attached to the report (with any alterations noted). Some lecturers will be happy with a reference to the method, e.g. 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. Method (or materials and methods) How you carried out the experiment (and what reagents you 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". For instrumentation-based practicals it is customary to mention the apparatus to be used. The simple report is generally only two to five pages long, and usually consists of the following:Īims (or objectives) The purpose of the experiment
