Laboratory safety rules are presented to the students at the first week.  Students are then asked to achieve at least 90% of a safety quiz in order to start laboratory experiments in the second week.  Students are required to present MSDS and to state special safety precautions in the lab report for each experiment if necessary.

Demonstrate a basic knowledge of handling of chemicals and safety procedures in a laboratory and develop an understanding of the effects of those practices on human health and environment.

The first 6 weeks of experiments are based on a specific food product provided to each team.   Each team presents a written report by evaluating the results of the analysis on the basis of requirements of legislation, labeling, exporting, etc., or of detection of adulteration.

Demonstrate an ability to use knowledge from various courses in an integrate manner.

Each student is required to write a laboratory notebook, which is collected after the completion of experiments for correction.  Those notebooks are returned back to students and they continue to write analysis of the 2nd project.

Demonstrate an ability to write a laboratory notebook.

Take corrective action based on feedback from others.
