LABORATORIES

Lab format: Six laboratories are scheduled for this course. Each lab will include a one hour lecture followed by physical experiments conducted by groups of five to six students. Note that most groups will have to conduct the experiments at a time different from that given in the timetable. Think whom do you want to join with in a group. Individual lab report is required for each lab (see below).

The labs will begin early in September and run till the end of November. Details of timing, student assignment to a specific group and other related matters will be announced during the lectures.

Lab Report: The report is to be typed with a minimum of five pages and a maximum of eight pages including title page, plots, drawings and appendix. Following format is to be used:

A. Cover page: Institution, student name & ID, Lab title and an executive summary

B. Body of the report:

  1. Objective
  2. Theory and background information
  3. Laboratory procedures used
  4. Recorded data, its analysis and results; use graphs if applicable
  5. Discussion and recommendations
  6. References

C. Appendix (if applicable)

Check the course Blackboard site for a sample

Report due date: All reports are due one week after the lab took place. Penalty of 30% will apply if the report is submitted up to one week late, 50% during the second week and 100% for reports more than two weeks late. Yes, you must submit the report even with the penalty is 100%, if you want to earn a credit for this course.

Lab marking:Each lab report will be worth 5% (for the total of 30 % considering that there are six labs in this course). In addition to lab content and organization, lab report will also be marked on format and writing (up to one-fifth of the mark).

Attendance: Attendance is mandatory, except for unusual circumstances brought to the attention of the instructor in advance and approved.

COMMENTS

  • Attend the lectures, as some of the material may not be well covered in the references. Take notes. Listen to the announcements and obey the deadlines.
  • Secure access to the listed references and make sure that you review those when appropriate.
  • If you experience problems with this course contact the instructor without delay.
  • Talk to your friendly lecturer if in trouble, if you experience difficulties or if you have any other problems. The sooner you talk the better the chance that the problem will be solved.
