Hi Bloggers and welcome back to another one of my blog posts!
This week in science we are doing a blog post to share our learning throughout. This term we looked at forensic science including: the different roles people had that were a part of it, what they do, and who they work with. The different roles/jobs people have are the following: fingerprints, footprints, blood spats, and hand writings.
What is Forensics?
Forensic science is a type of job where people investigate in different crime scenes to help officers, lawyers and law suits choose who is the culprit/murderer/stealer of that crime scene.
What we learnt about Forensics:
1. How do forensic scientists use patterns to find the truth?
Forensic scientists use patterns to find the truth by identifying/comparing pieces of evidence from people’s foot prints, fingerprints, blood spats/splats or stains, to find out who might be the culprit.
2. Compare two types of evidence. For example, why are fingerprints more “individual” than blood spatter or shoe-prints?
In my opinion, I think this is because fingerprints are more individual and unique, but a blood spatter doesn’t show who did it instead it tells us how the crime scene happened. Shoes on the other hand is way different because lots of people own the same shoes which makes it harder to find the culprit.
3. Describe a fictional crime scene where a footprint and a trait (like hair colour) are used together to narrow down a suspect list?
A late night break happened in a small town’s apple store. Many phones were stolen and right by the broken window there was a muddy footprint, which was soon investigated by the police and forensic scientists
4. Explain the importance of not contaminating a crime scene?
It is extremely important not to contaminate a crime scene because it might make someone else go to jail instead of the real culprit.
If I had to be a Forensics scientist I would be a: Crime scene investigator/Officer because I liked how we looked at the patterns of our finger prints and I learned out the 3 different types of patterns which is: Loop, Whirl, and Arch.
They kind of look like this:
My crime scene:
It all started in a rainy Saturday and lunch time in the school library. Everyone was going in to the library talking loudly, eating secretly, etc. The Liberians and on some teachers tried to take everyone out and make it into an inside lunch break. After everyone had left suddenly Nicole spotted a pink shoe print stained on the carpet!
Evidence:
Pink nike shoe print, in the library, from a student or teacher that probably ate something pink, size 15 footprint.
Suspect list:
Alice: Looking for a pink science book (Shoe size: 15)
Nicole: Baking cupcakes with pink icing (Shoe size: 15)
Mandy: Doing homework in her pink note book (Shoe size: 10)
Richard: Having lunch with his friends (Shoe size: 15)
Write your answer down in the comments
Answer for my crime scene (Culprit): Nicole (Why: Because she was baking cupcakes with pink icing, And her footprint size was a size 15.)
Did you get it the answer right without cheating?
