2001 U. S. NATIONAL CHEMISTRY OLYMPIAD NATIONAL EXAM—PART III Prepared by the American Chemical Society Olympiad Laboratory Practical Task Force OLYMPIAD LABORATORY PRACTICAL TASK FORCE Lucy Pryde Eubanks, Clemson University, Clemson, SC Chair Robert Becker, Kirkwood High School, Kirkwood, MO Craig W. Bowen, US Naval Academy, Annapolis, MD Nancy Devino, ScienceMedia Inc., San Diego, CA Sheldon L. Knoespel, Michigan State University, East Lansing, MI Steve Lantos, Brookline High School, Brookline, MA Jim Schmitt, Eau Claire North High School, Eau Claire, WI Robert G. Silberman, SUNY-Cortland, NY Christie B. Summerlin, University of Alabama-Birmingham, Birmingham, AL DIRECTIONS TO THE EXAMINER–PART III The laboratory practical part of the National Olympiad Examination is designed to test skills related to the laboratory. Because the format of this part of the test is quite different from the first two parts, there is a separate, detailed set of instructions for the examiner. This gives explicit directions for setting up and administering the laboratory practical. There are two laboratory tasks to be completed during the 90 minutes allotted to this part of the test. Students do not need to stop between tasks, but are responsible for using the time in the best way possible. Each procedure must be approved for safety by the examiner before the student begins that procedure.
