For this lab we were assigned to try to solve a murder mystery. We were given multiple pieces of evidence including fingerprints, blood samples, family histories, how the murder happened, and more. We had to use what we had to find who was most likely the person that committed the murder. You can watch our final presentation below:
CONTENT:
- Forensic Science: The application of science to crimes and crime scenes, used to help solve cases
- Fingerprint dusting: searching the area for fingerprints and using the pattern to find whose they are
- Blood types: Everyone has the blood type of either, A, B, AB, or O. Matching blood types can be used as more evidence
- Ink chromatography: In ink chromatography, we use a solvent to separate out the different dyes in the inks and we can match pen types, so we can get an idea of who could have written something
- Pedigree: This shows the families history of disease, blood types, relations, and deaths
REFLECTION:
This lab was very interesting because it taught me a lot about how forensic science works and what they do. It was quite fun solving the mystery by piecing together the evidence and seeing just who it could be. Some things we could have improved on were actual lab technique, for we were brand new to these practices. One example of this was that we initially had some incorrect results while testing the blood types. we also had some issues with organizing and recording of information, and ended up having to search around to find some of our evidence. On the other side, I felt we did good work finding out who the most suspicious person is. I also feel we did quite well with communicating the information we gathered with our group. For example, we had a teammate that was out sick for a day or two and we caught him up to speed really fast. Over all I think this lab was a success.
