Crime+Busters

= Science Crime Busters =

Types of testing may include identification of white powders, metal identification, fingerprint/ shoe print/ tire tread analysis, chromatography, etc. Teams will then be asked to analyze the information they have gathered to identify a suspect and solve the crime.
 * Description:** This is a Lab based event. Teams will be given a written crime scenario which they will be asked to solve based on evidence they gather and test.
 * Materials**:Bring to competition:
 * 1) chemical splash goggles,
 * 2) safety apparel, (lab aprons below the knees, gloves?? closed to shoes, long pants to ankles.)
 * 3) Safety knowledge: you must know how to handle each chemical correctly.
 * 4) a writing instrument.
 * 5) Also bring small containers or reaction plates for mixing,
 * 6) something for scooping,
 * 7) pH paper,
 * 8) a magnet,
 * 9) a hand lens,
 * 10) microscope slides and cover slips,
 * 11) forceps or tweezers,
 * 12) a pencil (for chromatograms),
 * 13) paper towels

What else should you know???? Event leaders will not answer questions on

 * 1) Testing procedures
 * 2) How to perform a burn test on powders
 * 3) Rules
 * 4) Possible unknowns.
 * 5) Any Procedure
 * 6) You should include a list of the possible unknowns in your allowed notes if you cannot remember.
 * 7) Event leaders WILL answer safety questions, and stop students from performing a test in an unsafe manner.
