Height and Feet Measuring

THE FEET CAN MEASURE THE HEIGHT


The bones of the feet can tell a lot about a person. What do feet reveal about a person's height? Forensic anthropologists team up with law enforcers to help solve crimes.
Bones of the feet can reveal an interesting fact about an individual. Let's combine math with forensics to see how.

Aim:  To use forensic science techniques to measure the height of a criminal.

Material:
  1. Metre Rulers 
  2. A Foot
  3. A Person
  4. Flat Wall

Steps:

  1.  Get a person that you can measure.
  2.  Grab your metre rulers.
  3.  Get the person to go to a flat surface(a wall)
  4.  Record the person's height.
  5. After that, lay their foot on a ruler and measure.

Findings:


Name
Foot  (cm)
Height (cm)
Lars22.5 cm151 cm
Axle26 cm160 cm
Vann25.4 cm163 cm


Divide the length of each person's foot by his/her height. then multiply it by 100. 

Lars: 14.9cm

Axle: 16.2cm

Vann: 15.5cm

Forgery

Graphologists are forensic experts who look at handwriting.

Many things can be forged: artworks, money, writing, etc

Aim: To Analyse a signature using forensic science.

Material:



A pen / pencil
Tracing Paper
Writing paper
A ruler


Steps:

A. Top Of Letter Analysis

1. Sign your name on a sheet of writing paper and get someone else to try to copy it.
2. Place the tracing paper over both signatures and make a dot at the top point of each letter – for both signatures.
3. Join up the dots for both signatures to get two zigzag lines across the signatures. Are the lines the same?

B. Bottom of Letter Analysis

1. Put some fresh tracing paper over both signatures.
2. Put a dot at the bottom of each letter.
3. Join up the dots to make zig zag lines. Are the lines the same?

C. Slant Analysis

1. Put a fresh piece of tracing paper over both signatures.
2. Mark a vertical line down through the middle of each letter (using a ruler), slanting it in the same direction as
the letter.
3. Compare the set of lines for both signatures. 
What do they tell you?

Findings:



You
Friend
Top Letter Analysis
Are the lines the same?

Yes, it's the same on the top letter.
Bottom Letter Analysis
Are the lines the same?

Almost, but it's not even in the bottom letter.
Slant Analysis
What are the slants telling you?

Almost.


Conclusion:









Activity: Get someone to try to forge your signature and then try both of these methods to analyse it.

Write up the findings based on the following questions.


  Writing an analysis of a friends forgery.
     



The size of the letters – all big, all small, mixed?

Where they dot the ’ i ‘– over the top or off to the left or off to the right, or not at
all


How they cross their t – straight, angled up or down, where on the t stroke it
is crossed


The slant of the letters (use a ruler) – forward, backward, upright, mixed


Are there breaks in words, or are all the letters in the words joined up


The length of stalks on y, q, p, below the lines – long or short

Brotherhood: The Completion

The end is near! For our film that is; the production of our film is coming to an end, finally! Currently, now we are on post-production which is editing all our 200+ shots. there have been many challenges over the time that we have been working on this project, ones that we had to push over and do. Though there were limitations on what we were able to do my partner and I are proud of what we have achieved through the course of this voyage in stop motion. There was a lot to be learned and a lot to be conquered; as if solving puzzles after puzzles until you get to the satisfying and gratifying finish that you've been aiming for.  We have experienced and learned a lot from doing and moving forward to this project which I'm sure we will be able to use in the rest of our lives, and a memorable feat that we have accomplished.

1. What is the definition of forensic science? 

scientific tests or techniques used in connection with the detection of crime.


2. Name 5 different kinds of activities used in forensic sciences and find a picture for each.

  • FingerprintsImage result for fingerprints
  • D.N.AImage result for dna
  • FootprintsImage result for foot prints
  • BallisticsImage result for ballistics
    • White Powder TestImage result for white powder test


3. Name 5 jobs that would use forensics to investigate crime 

  • Forensic Medical Examiner
  • Forensic Engineer 
  • Forensic Accountant 
  • Crime Scene Investigator
  • Crime laboratory Analyst

Aim: To look at the different types of fingerprints.
Image result for fingerprint types

Record the types of fingerprints from those in your group.

Name
Fingerprint 1 ( Thumb)
Fingerprint 2 (finger)
AxleLoopWhorl
VannWhorlArch
LarsLoopArch


Summary of findings: We learnt that each fingerprint is different and that there are different kinds of fingerprints. I also found out that each finger has a different fingerprint. 







Hidden fingerprints:

Aim: To learn how to lift hidden fingerprints from an object.

1. Lifting and Gathering fingerprints.

Equipment:
  1.   Balloon 
  2.   Fingers
  3.   Finger Stamp Pad
Method:
  1. Grab a finger stamp pad and a balloon.
  2. Put your thumb or finger on the stamp pad. 
  3. When you have stamped your thumb or finger, grab the balloon and put your finger on the balloon.
  4. Blow the balloon and you should see your fingerprints.
