Note: the event leader will be providing the chromatography paper to match the samples run in advance from the crime scene.
Description: Given a scenario and a list of possible suspects, teams will perform a series of physical and chemical tests. These test results, along with other evidence, will be used to solve a crime and identify the suspect. The 2017 topics are powders, fingerprints, and toolmarks.
Materials: Teams must bring something to write with and safety goggles. Teams may also bring a tool kit with the following items:
1. Spot plates, paper cups, or any containers in which teams can perform the tests
2. Droppers, popsicle sticks, spatulas, plastic spoons, tongs, and/or forceps for handling materials
3. pH test strips or paper,
4. A ruler,
5. A wash bottle or dropper bottle of distilled water,
6. Hand lenses or loupes,
7. Paper towels,
8. A disposable cup for solid waste,
9. Writing instruments,
10. Safety gear. The event supervisor will inspect kits and confiscate any non-allowed items.
Recommendations: The biggest problem elementary teams have is time management. Be prepared to divide and conqueur parts of the test, or you may not get done.
High Score wins. Points will be assigned as follows: Chemical evidence 50%, physical evidence 30%, analysis of the crime 20%. Ties will be broken based on best score in the chemical evidence section.
