9 Requirements Lab performance Write-ups: technical writing Fundamentals of each lab
10 Lab performance Be prepared for: ObjectivesTheory / knowledgeDesign of experimentParameters to be measuredApparatuses, procedures and principlesFind out: what to learnInitiate the contact for the pre-lab helpwith the lab coordinator
11 Lab performance Follow experimental procedures During the experiments:Follow experimental proceduresRecord observations in Lab NotebookTest the validity of data and/or resultsPay attention to SAFETY issuespersonnelequipment
12 Laboratory SafetySafety is the responsibility of everyone and everyone will be held accountable.Safety glasses are mandatory, no exceptions.Contacts should not be worn.Lab coats are mandatory.Absolutely no food or drinks.Several of the experiments involve chemicals which are toxic and hazardous. It is important that YOU know where all the safety apparatus are.
13 Know where the emergency exits are. Be familiar with the Departmental Safety Manual.Know where the MSDS information is.
14 Pre - Labs Pre-labs are not mandatory but are strongly recommended. All partners must be present.The laboratory is running two classes this term with an enrollment of 112. Please schedule accordingly as the 3rd year class will be slow.Pre-lab times are posted on the class website.
15 Write-ups / Reports Technical memo Brief report Formal report Lab notebook: during the experiments
16 Write-ups / Reports Evaluate - understanding from the experimental labs.- technical writing skillsTechnical content: academic theory, results.Writing: organized, neatLanguage: no grammar or typographic errorsCommunication: clear delivery
17 Write-ups / Reports Each student is required to hand in 2 technical letters1 brief report1 formal report1 lab notebook
18 Write-ups / Reports No repetition in each group for formal report brief reporttechnical letters
19 Write-ups / Reports You Your partner Tech. letters Labs A and B Labs C and DBrief reportLab CLab AFormal reportLab DLab BLab notebookLabs A,B,C,DIn one group, you may label the 4 labs by A, B, C, and D in your own order.Each member of the group should keep the same order.
20 Permanently bounded & recorded Lab NotebookNo sheets of paperPermanently bounded & recordedBriefly outline the title, apparatus, experimental conditions and procedures before labsSuggest making table for recording dataRecord clearly all original observations& simple calculations of dataMUST be examined, dated and initialed by the TA’s before leaving the laboratoryAt the precise moment when a particular observation is made, it might seem unimportant, but sometime later that could prove too be the most significant aspect of the entire exercise.
21 Lab Notebook Refer to the class website for : RULES FOR LABORTORY NOTEBOOKSSubmit the lab notebookat the end of the term for marking
22 Technical Memorandum Body of text: maximum two pages Introduction - concise introduction of the system used- a brief statement of the objectives of the experiment- a general description of the procedure followedResults- discussions and comparison of all required results with values from literature- a brief table of results can be inserted into text of memo- major graph attached to support the conclusions Conclusions and recommendationsSign your memo on the last page below the text

27 Formal Technical Report AbstractState briefly the purpose of the investigationDescribe briefly how the results are obtainedGive all required results in a concise and quantitative format if possible.Use words, no tables, figures and equationsNormally no more than 250 words.
28 Formal Technical Report NomenclatureCompletely lists the symbols that appear in your report, their definition and units in a professional and consistent format.Refer to a published paper.
29 Formal Technical Report IntroductionInclude information on the subject of the investigation and its importance in industryCite the references;Describe clearly the objectives of the lab.
30 Formal Technical Report Literature review or theoryProvide sufficient theoretical backgroundto the particular experiments.Develop the equations or models to correlate your experimental data.detailed derivation placed in AppendixDescribe how to obtain the model parameters and predict the particular systemCite the references
31 Formal Technical Report Apparatus and Experimental ProceduresSpecify the main apparatuses usedmake, model and useDescribe the proceduresHighlight important experimental conditionsGive the names and quality of the materials.Make sure other people can repeat your work and obtain the same results if they follow your description.
32 Formal Technical Report Results and DiscussionsPresent the significant experiment resultsrequired in the Lab Manual in words and graphs.State the data treatment processes and the outcomes.Discuss the results of experiments and model simulations or predictions.Compare your results with that in literature if available.Logically discuss and lead to conclusions.
33 Attention Consistent format Conformity of units Figures or Tables in the body of textTitles of figures, axes, and tablesBriefly state the experimental conditionsExperimental data: represented by unique symbol for each group of data in figuresModeling curves: different lines with legendsShow model significance when fitting models
34 Formal Technical Report Conclusions and RecommendationsConclusions should be summarized following the discussions.Lists your suggestions on how we can improve the labs.
