The report should contain, in the order described: 1. Cover sheet, with your name, the names of your partners, the instructor’s name, the title of the laboratory exercise, and the date on which it was performed. 2. Briefly explain the purpose of the experiment. 3. The original data sheets must be submitted even if copies revised to look neat are included. 4. Graphs. Every graph should have an appropriate descriptive title. All graphs should be prepared neatly and carefully, with the axes labeled clearly and the scales chosen for maximum clarity. Make your graphs large enough so that data points can easily be read from the graphs. If the graph calls for a straight line or a smooth curve fit, make sure that you follow proper procedures for doing this. Your instructor will give you appropriate guidance in this. You should never simply connect the dots on a graph. If your graphs are generated by a data acquisition and analysis program in a computer such as Vernier Logger Pro, you can include a print-out of the graphs. You may also use the data from the data acquisition system and plot your own graph using a computer program such as Excel. You do not need to include the raw data from the data acquisition system in the report. 5. The results should be tabulated and clearly labeled. This should be a ruled table summarizing the final computed results (not the data), together with the accepted values for these computed results whenever they are known, the standard deviations of your results, and also the percent error of the quantities in question. 6. The calculations used to obtain the tabulated results. These computations are based on the original data taken in the laboratory and include all quantities asked for in the instructions. If the calculations are very repetitive, it is sufficient to show a representative calculation. 7. A discussion of the results obtained, the uncertainties in your measurements, a comparison with accepted values if appropriate, and the possible sources of error in your measurements. Your discussion of the experiment should be written only after you have completed the calculations, drawn up a tabular summary of the results, and plotted all graphs called for. Your discussion need not go into the theory of the experiment insofar as it is covered in the text, but may well take up any point of interest not discussed in the text. The discussion should never repeat procedure. It should certainly contain a comparison of the results actually obtained in the experiment with results to be expected as well as a meaningful discussion of limitations in the experimental procedure and possible sources of error. A further discussion is given below. 8. A conclusion in which you discuss the significance of your results and summarize what has been learned from the experiment. 9. Answers to all of the questions posed for this laboratory exercise.
