If you have a physical, psychological, medical or learning disability that may impact on your ability to carry out assigned course work, I would urge you contact the staff in the Disabled Student Services office (DSS), room 133 Humanities, 632-6748/TDD. DSS will review your concerns and determine with you what accomodations are necessary and appropriate. All information and documentation of disability is confidential.

ESM-302 Laboratories Spring, 1999

The practical aspects of this course will be carried out in Room B001 Old Engineering (Basement) on Monday evenings from 6.00 to 9.00 P.M., and in the various laboratories in the Department of Materials Science and Engineering. Students are to familiarize themselves with the safety precautions in the laboratories. Read all posted safety instructions.

NEVER TOUCH OR HANDLE EQUIPMENT THAT YOU ARE UNFAMILIAR WITH. The laboratory rooms will only be open at the specified times. Students will not be allowed to work in the labs outside of regular hours.

Laboratory Reports, Homeworks, etc...

Unless advised otherwise, all laboratory reports, homework assignments, problems, etc. handed out during class or in the respective laboratories are due from each student following the completion of the experiment. All reports are to be handed to me for grading either at the Lab (for experiments) or in class (for homeworks). NO LATE REPORTS WILL BE ACCEPTED. As many of the homework assignments and laboratory worksheets will be dealt with in class, attendance in the lecture is mandatory. For worked problems the student should show all steps in the answer. Descriptive reports should consist of a statement of the objectives, a brief discussion of the underlying theory that is in the handout or lecture notes or from the assigned references, a description of the experimental techniques and materials used, followed by a presentation and discussion of the results. The report should be brief and concise, 3-5 pages, double-spaced, maximum. The relevant calculations and /or graphical or tabular summary of the data should be included as an Appendix. Constructive criticism of the style and writing will be provided. A poorly designed and written report cannot receive a high grade.

Laboratory Notebook

You will need a notebook, calculator, tracing paper, mm.graph paper and a ruler. The work in the laboratory will be complemented by problems and worked examples which you will do in conjunction with the lectures. Hence a dedicated notebook, free of superfluous material will keep all the relevant information together and readily accessible.
