Why Lesson Planet?
Sixty multiple choice questions cover the entire gamut of chemistry concepts. This is the local section of the U.S. National Chemistry Olympiad, where your chemistry candidates take a shot at entering the national competition. They answer questions about everything from properties of liquids and phase changes, to electrolysis products and molecular geometry. You could actually use this as a final exam for your class, a course review, or a practice for the actual chemistry challenge.
