In forensics there many different types of ways to analyze a crime scene. You can use lasers, cameras, and even your own eyes.


  • Lasers are a high concentrated beam of light, it starts off as a weak light & continues to add more energy, making it more concentrated. They are a monochromatic light meaning they use only one color at a high frequency.
  • The purpose of the laser in forensic science, is to illuminate hidden fingerprints. This method is faster and a bit more accurate to find finger prints. The reason why, is because they don't use no method of powder or anything like that. Instead it uses light & it shows you the fingerprints & once found, they collect the fingerprint & take it to a lab & analyze it.


  • It captures light created by the flash. The light that is created, reflects off of the objects & goes through the lens. The lens then slows down the light because it's going too fast, as it slows down it makes the picture look exactly like the scene. If you hold the camera at a certain angle it will become blurry, the reason for this is because light is entering at a weird angle that's why we focus it.


  • Your eyes work similar to a camera.
This works similar to a camera as shown in the image above which makes it an important role in forensics.
The process of analyzing and collecting evidence.

Collecting Evidence

  • CSI look for these thing at scene when they are trying to collect evidence:
  • Blood, fingerprints, hair samples, impressions.
  • They also look for other things like tool marks & also controlled substances. Collecting evidence is easier than analyzing evidence because most programs don't have the proper funding.

Analyzing Evidence

  • CSI need skills in chemistry, math & also computer science.They will sometimes have to recover evidence off computer and analyze the information they get. Unlike TV shows, forensics labs aren't fully equipped you may have to send collected evidence to another lab to get results because your lab doesn't have the right equipment.

Protocols and Regulations

  • CSI have to follow the 5 steps;
  • Interview, examine, photograph, sketch & process.
  • They also have to record the scene which they can use later in the investigation & court room
Describing clothing in Spanish


  • Stripes, colors, & polka dots.
  • Knowing the clothing pattern in Spanish creates a visual data transmitter because when you explain the clothing you used to hide your transmitter, you need to be able to describe the pattern of the clothing you used in Spanish, & explain why you decided to use that kind of pattern to hide your transmitter in.


  • Cotton, linen, & silk.
  • Knowing the type of frabic that people in Chile wear is important when relating to how we are disguising our transmitter into the type of fabric they use. Also we need to be able to explain type of frabic used to them in Spanish just in case they don't know English.


  • Red, orange, & blue.
  • The color of the clothing in Spanish is important because knowing the colors in Spanish can describe the colors, & explain why we used the colors to them in Spanish just in case they don't understand English.
Knowing body parts vocabulary in the target language is important for agents in the field but also helps us with the creation of the product.

Body Parts

  • The human body has more than 20 parts so when it came to designing the product we focused on the main parts like the arms, shoulder, eyes, & ears. We focused on these main areas because of the obvious reason being that even in our selected country they still identify these parts of the body as we do but just in a different language

The Designing Process

  • Design the product to be able to stay hidden or blend in with the surrounding body parts.
  • The main objective was to make sure the device isn't easily noticeable or detectable by others. So my team focused on what parts of the body are commonly used, the most with other accessories & not catch any unwanted attention. So after looking at animals around the area we decided to base our glasses off of the similar characteristics of camouflage enabled animals.
