Group Topic Response:

Forensics has many different things that can lead to an answer. We feel that we can really be involved and go in different directions with the topic. We can do things like building and researching lie detectors, figuring out what leads to finding and taking a finger print, and researching how D.N.A. is processed to result in an answer. Lie detectors can sometimes find if someone is telling the truth or not. Lie detectors will determine this by examining a person’s amount of perspiration, their heart rate, and their blood pressure. When a lie detector is used an investigator wills ask a person a series of questions and then look back at the results to determine if they are lying or not. Lie Detectors can be easily fooled though since people react differently to lying. The next thing someone can use is fingerprinting. Fingerprinting is recording someone’s fingerprint then comparing it to another to discover what he or she needs to. Someone can discover a fingerprint using a powder that they would dust over surfaces. A fingerprint can also be found by analyzing an object on a computer. Either using a powder or ink takes a fingerprint. Fingerprints can be swirled or looped. Every single person has a different thumb print. D.N.A. can also be taken for the same uses as a fingerprint to compare to one thing to compare to another. D.N.A can be things like saliva. Someone’s D.N.A can be taken by something they had in the mouth like a water bottle or even taking just a swab from their mouth. We think we should do this project because there are so many hands-on activities we could do and experiment with. We also think we should do this project because it is something that will take extensive research and testing so we think it could fit really well into the time slot we are given as far as presenting and completing the project. Another reason is that Emma might be able to get someone for us to question about Forensics. The last reason why we think we should do this project is that we can really go in a lot of different directions with the topic because there is a lot of tests and such that will be done to result in an answer in that area of work.
