The course will be presented using lectures, problem sessions, small group activities, and practical demonstrations. Video and other audio-visual aids will be used where appropriate. When the nature of the experiment permits, lectures and laboratory experiments will be integrated to allow for discussion and analysis of results. More formal lab sessions will be conducted for those experiments having safety implications. Projects and homework will be assigned to be done individually in person or on-line, or in small groups.

Tests and Examinations (40-60%)
Two in-class tests will be given during the semester (10-15% each) and a final comprehensive exam will be written at the end of semester (20-30%).
A report will be required for each laboratory experiment. One complete write-up will be required, the remainder will involve pre-formatted report sheets. Some of these reports will be marked Pass/Fail.
Problem assignments will be handed out regularly to be done by small groups or individual students, or on-line.
