To analyze and identify several unknown substances You are a Forensic Scientist who has been tasked with analyzing and identifying two unknown substances collected at a crime scene. You will provide a report to the police department as to the nature of this substance. In addition, you may be asked to make a presentation of your findings to other scientists The police department is investigating a burglary. Several unidentified substances were discovered at the scene. The police need to identify these substances in order to determine if they are relevant evidence. They call you up to help them because you should have just completed the lab activity “White Around You” from HST Red pp. 602 – 603. You will create a short report describing the following for each substance: • Physical properties (such as state, color, form, mass, volume, etc.). • Calculations of its density when provided with the mass and volume of the substance • Chemical properties (reactions with other substances). • Probable identity. • Possible source in context of the crime scene. Your product must meet the following standards: • All physical and chemical properties are correctly identified. • Calculations of density are shown for each substance. The calculations can be verified as correct. • All substances are identified. In case of similarities, two possibilities may be named along with data to support the identifications. • All data is recorded in an easy to read format. • Data tables are correctly labeled. You will have one complete class period to do your tests and report.
