9 Requirements Lab performance Write-ups: technical writing Fundamentals of each lab

10 Lab performance Be prepared for: Objectives Theory / knowledge Design of experiment Parameters to be measured Apparatuses, procedures and principles Find out: what to learn Initiate the contact for the pre-lab help with the lab coordinator

11 Lab performance Follow experimental procedures Record observations in Lab Notebook Test the validity of data and/or results Pay attention to SAFETY issues – personnel – equipment During the experiments:

12 Laboratory Safety Safety 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 3 rd year class will be slow. Pre-lab times are posted on the class website.

27 Formal Technical Report Abstract State briefly the purpose of the investigation Describe briefly how the results are obtained Give all required results in a concise and quantitative format if possible. Use words, no tables, figures and equations Normally no more than 250 words.

28 Formal Technical Report Nomenclature Completely 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 Introduction Include information on the subject of the investigation and its importance in industry Cite the references; Describe clearly the objectives of the lab.

30 Formal Technical Report Literature review or theory Provide sufficient theoretical background to the particular experiments. Develop the equations or models to correlate your experimental data. detailed derivation placed in Appendix Describe how to obtain the model parameters and predict the particular system Cite the references

31 Formal Technical Report Apparatus and Experimental Procedures Specify the main apparatuses used make, model and use Describe the procedures Highlight important experimental conditions Give 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 Discussions Present the significant experiment results required 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 text –Titles of figures, axes, and tables –Briefly state the experimental conditions –Experimental data: represented by unique symbol for each group of data in figures –Modeling curves: different lines with legends –Show model significance when fitting models

34 Formal Technical Report Conclusions and Recommendations Conclusions should be summarized following the discussions. Lists your suggestions on how we can improve the labs.
