Due Date and Overdue Penalty• Due date for the reports:
- 2 weeks after the experiment date.- The date of submission is counted by the date on which the hard copies of your reports are handed in to and signed by Mr. Dale Claude.
AND- Electronic copies of the reports must be sent to both Dale and Drs. Zhang/Niu by email on the same day for verification.- When submission on weekends, the date of submission of reports by email can be counted, however, the hardcopies of your reports must be handed in to Dale on the following Monday to avoid extra delay penalty.
- 7 “free” late hand-in days for the whole course - Must indicate on your reports when use it to avoid late
penalty.
Due Date and Overdue Penalty
Penalty

Table of contents
(Double spaced, max 20 pages)
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.
Formal Technical Report
Introduction
• Include information on the subject of the investigation and its importance in industry;
• Describe clearly the objectives of the lab;
• Cite the references.
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. Number the equations.
detailed derivation placed in Appendix
• Describe how to obtain the model parameters and predict the particular system
• Cite the references
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 of quality of the materials.
Make sure other people can repeat your work and obtain the same results if they follow your description.
Formal Technical ReportResults and Discussion
• 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 literatures if available.
• Logically discuss and lead to conclusions.
Attention• Consistent format
• The unit for every parameter in the equations has to be conformed.
• 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

Oral Presentation– Each group is required to deliver one oral presentation
based on the lab they have performed.
– The content of the presentation should include introduction of the lab, theories and/or principles, objectives of the lab, experimental procedures, data collection, data processing, results and discussion, conclusion and recommendation.
– The duration of the presentation is 13 -15 minutes.
– All the students in the same group will work collaboratively, and will be evaluated as a group.
– All students must attend the group presentations and participate the grading. Irresponsible grading will lead to reduce of the overall marks.
A good report/presentation• Careful measurements• Correct calculations• Understanding and use of the
theory or models• Logical discussions• Correct conclusions
Organized
ClarityNo grammar & typographical errors
• References• Oral presentation
