Given a scenario, a collection of evidence and possible suspects, students will perform a series of tests. Test results along with other evidence will be used to solve a crime and answer questions.
Each participant may bring one 8.5×11″ sheet of paper, which may be in a sheet protector sealed by tape or laminated, that may contain information on both sides in any form and from any source without any annotations or labels affixed. Each team may bring any or all of the items listed on the Division B Chemistry Events Lab Equipment List included in the Official Rules Manual. Each participant may have a stand alone non programmable non graphing calculator. Participants must wear goggles, an apron or lab coat and have skin covered from the neck down to the wrist and toes. Gloves are optional. Hair must be tied back. The Event Leader will provide Iodine reagent, HCl, Chromatography materials plus containers, waste containers, wash bottle with distilled water, as well as other equipment.
High score wins.
– Be sure to follow all safety requirements! Safety issues will NOT be arbitrated.
– Event leaders will not answer questions on testing procedures (for example- how to perform a burn test on fibers) nor will they provide a copy of the rules or a list of the possible unknowns. Teams should already know procedure, and should include a list of the possible unknowns in their allowed notes if they cannot remember. Event leaders WILL answer safety questions, and stop students from performing a test in an unsafe manner.
Will students need to perform flame tests for fibers in 2024? No!
