Lab Report Template Chemistry

Lab Report Template The template below has been provided to assist you in preparing your lab reports. Please use it by filling in the highlighted areas. For short lab reports, fill in the necessary sections and delete the ones that do not pertain. Some things to keep in mind: You must pass the lab component in order to pass the course (minimum of 60%) All reports must be submitted through Moodle For late submission of a lab report, you have three (3) grace days in the semester. Once those are used, any late report is an automatic zero Every student must submit their own lab report, even if the experiments are done in pairs/groups. At the end of every laboratory session, make sure your instructor signs your data sheet and pre-lab work. Write in full sentences, in the past tense, in third person (no personal pronouns). Do not copy the lab manual, plagiarism is a serious offence and a grade of zero will be given. o The procedure written before a lab can be have short segments written word for word from the manual if that makes the most sense to you Font size should be a minimum of 12, pages should be numbered When “0” is trailing and is significant, it has to be written down (ex: enter 1.6310 g and not 1.631 g, 25.00 mL and not 25 mL, 18.0C and not 18C). Physical pages that are attached into the report are done by inserting a scan of the page. Some possible smartphone apps to scan pages are: o Microsoft Office Lens o Adobe Scan o Camscanner o Tiny Scanner Short Report Only include sections (in order): o Title Page o Procedure (the one completed before the lab) o Signed Data Sheet o Sample Calculations o Post-Lab questions o References Full Report Title Page Objectives and Introduction Procedure Data and Results (signed sheet, graphs, tables, etc.) Sample Calculations Conclusion and Sources of error References Appendix o Post-Lab questions o Procedure (the one completed before the lab) Objectives and Introduction State objectives of the experiment. In paragraph form, describe essential concepts and theories. Be clear and concise, no more than one page. Include, and label, important chemical and mathematical equations in the experiment Procedure Not necessary to write this section if doing a short report Refer to lab manual (title, year, pages xx to yy). Modifications: If any Unknown Code: If any Data and Results The data sheet, IF CLEAN AND LEGIBLE, can be used in this section. Otherwise retype your results. Pay attention to significant figures, decimal places and units. Attach graphs, if any Notes for graphs: Prepare graph using software programs such as Excel, Numbers, etc. Graph may be prepared by hand, but use mm-graph paper. Graph should take up most of the page. Include descriptive title. Do NOT use ‘y-axis vs. x-axis’ as title, that’s obvious. What does the graph represent? Example, if y-axis is mass and x-axis is volume, don’t use ‘mass vs volume’ as title. Instead use ‘Density of Substance X’. Include labels and units on both axes. Maximize the graph area (axes don’t have to start at 0). Don’t connect the data points, instead, find best fit line/curve. Sample Calculations Show one calculation for each type performed in experiment. Highlight your result. Pay attention to significant figures, decimal places and units. Conclusion and Sources of Errors Summarize the important results obtained from the experiment, include % error (if any). Compare your results with the expected (theoretical) results. What do the results indicate? Were the objectives stated in the introduction achieved? Why or why not? Use your data in your discussion to help with your claim(s). List possible sources of errors and describe how the errors affected the results. Do NOT use the expression ‘human error’. Errors should not be related to a fundamental mistake in procedure.
