### Methods of Instruction

Classroom time will be divided between the presentation and discussion of concepts on the one hand and the application of these concepts in problem solving on the other. The laboratory program will involve weekly, three hour sessions during which students will perform a set number of experiments. Some group work will be required.

### Means of Assessment

The final grade in the course will be determined based on the following:

• final Exam - minimum of 30% / maximum of 40%;
• at least one midterm test - minimum of 20% / maximum of 30%;
• laboratory experiments - 20%;
• quizzes and/or assighments (possibly online) - minimum of10% maximum of 20%.
