Forgery

Graphologists are forensic experts who look at handwriting.

Many things can be forged: art works, 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:

Analyzing	You	Friend
Top Letter Analysis Are the lines the same?	The tops of these letters were not the same as mine  -  E,P,other E,T,O and the N	No the top letters aren't the same but are pretty close.
Bottom Letter Analysis Are the lines the same?	The bottom of these letters were not the same as mine - E,P,other E,T,O and the N	No the bottom letters aren't the same but are pretty close
Slant Analysis What are the slants telling you?	The letters that were not the same as mine are - S,T,E,P,T,O, and the N	No the letters aren't the same but 3 letter were the same - M,L and the letter E

Write up the findings based on the following questions.
For the top and bottom letters my friend Hope did pretty well. For the top letters Hope got 6 letters incorrect which was E,P, the other E,T,O and the letter N. For the bottom letters Hope got 6 letters incorrect which was E,P, the other E,T,O and the letter N. For the slant analysis letters Hope got 7 letters incorrect which was S,T,E,P,O and the letter N. But for the slant analysis letters Hope got 3 letter correct which was M,L and the letter E.

  Writing 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
