Forensic Teamwork Essay

According to my forensic teams research, the evidence sample contained starch. My team was also able to determine that the evidence sample dissolved in water ,and felt like a powder. Performing different tests helped to determine the ingredients that the evidence consisted of. First, my team performed a water test, by mixing drops of water with the substances A through E and the evidence sample. The forensics then conducted a vinegar test and an iodine test, to test for Co² and starch. Finally, a heat test was performed, and the changes were documented. Based on my team's results, Au Bond Foot Powder Extra strength was found at the crime scene. I know this, because the forensic team tested all of the ingredients and the evidence and compared them. I
The vinegar, iodine, and heat tests resulted in chemical reactions, because they either fizzed and produced a smell, or the color changed. It is important to always test a hypothesis, because The chemicals could have been tampered with. To be absolutely positive your findings are correct, retesting is a good idea. To avoid cross contamination during this experiment, the team washed out the tools after using them. To improve this lab, next time I would do this lab before all of the other forensic teams, to make sure all of the resources and substances that are being used are not mixed or tarnished. I would also make sure to make observations in detail. According, to my research, if two suspects were wearing the same brand of foot powder that was found at the crime scene, DNA would be the only way to tell who committed the crime. No two people have the same DNA, so if they match DNA to a person, that person committed the crime. Finally, police and fire departments use chemistry in real life by examining key evidence from crime scenes and performing tests. In conclusion, learning how to correctly test substances is important, because it may be necessary for future
