A conclusion should be written for each experiment. The conclusion should contain summaries of the actual experimental results, preferably in an easy to read format (such as a table). In addition, there should be a general statement drawing the data and the concepts together.

A good conclusion also includes much of what was stated in the objective. A conclusion starts with your experimental results, but must go beyond the results. It should tell what is done with these results and what they show or indicate. The conclusion should indicate what can be learned or "concluded" from the results. What insights do these results provide?

If your objectives indicate you were trying to determine something by performing the experiment, your conclusions should state if the determination was successful. For example, if you were trying to demonstrate the conservation of mass, did your results indicate that mass was conserved? If you were trying to determine which type of volumetric glassware was most accurate, then state which one was found to be the most accurate based on your results.

A crucial part of your conclusion is to explain clearly and completely what your results show or do not show relative to the purpose and objective of the experiment. You can also use the conclusion to indicate where there are problems with your results due to any errors or mistakes in your experimental procedures or techniques that you have been able to identify.
