Modified CSE Style guide Differences and Similarities Between Lab Reports in Chemistry and Biology Chem-Bio Alignment Chemistry Biology Introduction No direct quotes Everything except hypothesis(es) should be written in passive voice* Materials & Methods Passive voice* No direct quotes See pages 114-117 in Pechenik's chemistry text for level of detail Section may be titled "Materials" or "Experimental" Does not include equations Section may be titled "Materials" or "Materials and Methods" Equations in Materials in Methods section, not in results section Common practice to cite Results Passive voice* Graphs should be generated in Excel Instructor should discuss how to determine the best way to graph specific types of data (when to use a line graph vs. scatterplot with line of best fit) Tables should not be split with a page break Caption and respective graph should be on same page, not separated by a page break Show uncertainty if applicable Figure Captions All figures need to have captions (no titles) Numbered figure caption placed below figure** Should begin with a sentence fragment that reads like the title of a newspaper article What is plotted on each axis Other information needed to understand the figure (sample size, uncertainty, etc.) Table Captions Numbered figure caption placed above table** Should begin with a sentence fragment that reads like the title of a newspaper article Other information needed to understand the figure (sample size, uncertainty, etc.) Equations in results section, not in materials and methods section Need not cite equations that are found in most textbooks, such as standard deviation formula or integrated forms of rate laws Provide a sample for each type of calculation performed Equation editor must be used Results section may not require a description of the trends in paragraph form; may only contain tables and captions Most figures show scatterplot with line of best fit Does not include equations Results section requires a description of trends in paragraph form References figures and tables "(Fig.1)" in the order that they are presented Discussion How observed results compare to expected results (hypothesis) Do not address systematic errors without evidence What additional questions arose as a result of the study? How will you test those questions? etc. See Discussion Materials on TSAM Canvas site No direct quotes Students are more likely to refer to the textbook and lecture notes than to published papers Reflect on relationship between experimental error and deviation from expected results Last paragraph should summarize the experiment/study Students compare their methodology and results to those in published papers *There is a lack of consensus about the use of passive or active voice, so this may vary between courses depending on instructor preference. **This should, at minimum, be mentioned by the instructor. The instructor can choose whether this should be part of the grade.
