What is forensic science?
The application of science to criminal and civil laws
Forensic science plays a crucial role in legal investigations.
What does Locard’s exchange principle state?
If a person comes in contact with an object or another person, a cross-transfer of evidence occurs
This principle is fundamental in forensic investigations.
Who are crime scene investigators?
Specially trained personnel that travel to a crime scene to collect and preserve physical evidence
Their role is critical in ensuring the integrity of evidence.
What does forensic pathology involve?
The investigation of unnatural, unexplained, or violent deaths
Forensic pathologists often perform autopsies.
True or false: Eye witness testimony is considered reliable.
FALSE
It is a major reason behind most wrongful convictions.
Define spatter in forensic terms.
Bloodstains created from the application of force to the area where the blood originated
Understanding spatter patterns is essential in crime scene analysis.
What is the origin/source in blood spatter analysis?
Where the blood came from/originated
Identifying the source helps reconstruct the crime scene.
What is the angle of impact?
The angle at which the blood landed on the surface it resides
This angle can provide insights into the position of the victim and assailant.
What is a parent drop?
The droplet from which a spatter originates
Parent drops are crucial for understanding blood spatter patterns.
What are satellite drops?
Small drops that break off from the parent drop when the blood hits the surface
They can indicate the force of the impact.
Define spines in the context of bloodstains.
The pointed edges of a stain, which can help determine which direction the blood came from
Analyzing spines aids in reconstructing the events of a crime.
What is an independent variable?
The variable which affects the dependent variable
It is manipulated in experiments to observe its effect.
What is a dependent variable?
The variable which is the result of the change of the independent variable
It is measured in experiments.
Define a controlled variable.
Something which is always the same in the experiment
Controlled variables ensure that the experiment is fair.
Fill in the blank: I hypothesise that the paper planes with the bigger wings will travel more distance than the ones with smaller wings because the bigger wings will allow them to carry more wind and will allow it to travel further, at a slower pace. I hypothesise that _______ was true and the number of turned in homework increased after he started to give out detentions as a punishment.
