The course will be presented using lectures, problem sessions and class discussion. The laboratory course will be used to illustrate the practical aspects of the course material. Close coordination will be maintained between laboratory and classroom work whenever possible. This will be accomplished by discussing laboratory experiments in class and, when necessary, by using the lab period for problem solving.
Options: Students will be encouraged to view course material in the context of teaching through a combination of class presentations, cooperative learning and tutorials. Current educational technology, such as research using the Internet, molecular modeling software and data analysis with spreadsheets, may be employed.

Options: For classes with students enrolled in the Bachelor of Physical Education and Coaching program:
- Instructors will be aware that students in this class are seeking a career as teachers and therefore topics may be presented with a pedagogical perspective.
- Students may be provided with skills enabling them to explain both quantitative and qualitative topics in the course to an audience of elementary or high school students.
Laboratory Objectives
The student will be able to:
- Give the name and describe the use of common laboratory equipment.
- Accurately perform standard laboratory techniques using the accepted methods, such as titration, weighing, pipetting.
- Give the random and systematic errors inherent in each of the common quantitative techniques which are used in the laboratory.
- Write a report based on observations and data obtained in the laboratory using a standard report format.
- Given a set of experimental data or using data obtained in the laboratory, apply the appropriate mathematical techniques (e.g. graphical analysis, solution of equations, etc.) necessary to obtain a numerical result.
- Using the data, observations or results of an experiment, determine the relationship between experimental variables.
- Analyze the overall laboratory experiment with respect to errors inherent in the method or techniques.
- Give the theory upon which the experiment is based.
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
Lecture Material (75%)
- Two or three in-class tests will be given during the semester (30% in total)
- A final exam covering the entire semester’s work will be given during the final examination period (30%)
- Any or all of the following evaluations, at the discretion of the instructor: assignments, quizzes, class participation [5% maximum],presentations, research assignments, group work (15% in total)
Laboratory (25%)
Written reports for each experiment or activity will be handed in and graded. These reports may be of various types: complete reports, short reports (handed in on report sheets) or written research assignments. In addition, activities, such as written quizzes or online assignments, may be evaluated. Qualitative and quantitative results of experiments performed on unknown samples may be graded.
Note:
A student who misses three or more laboratory experiments will earn a maximum P grade.
A student who achieves less than 50% in either the lecture or laboratory portion of the course will earn a maximum P grade.
