DO NOW: discuss with partners for 2 minutes.

The chief threw the pillow at Mr. Cater and yelled, "The woman was smothered and this pillow was obviously the murder weapon! See if you can do something right for a change and get some dang

fingerprints!“

Mr. Cater took the pillow back to the lab and found a set of prints on it easily. Furthermore, he knew exactly who they belonged to and that the person was indeed involved with the case. But Mr. Cater didn't even think of considering this person a suspect. Why not?

AN ANSWER

They were the chief's prints. He put them there when he "threw the pillow at Mr. Cater."

LEARNING OBJECTIVE

Compare the 3 major fingerprint patterns of

arches, loops, and whorls, and their

subclasses

FINGER PRINTS (5 minutes)• You will read the first two pages of “Finger Prints” by Francis Galton from

1892

LEFT PAGE independent activity:

what do you think is the main idea of this reading?

ANSWER IN 2-3 COMPLETE SENTENCES

• Underline words you don’t know (there may be a lot of them; that’s okay)• Circle important concepts and key words that help you determine the

main idea.

CHOOSE

Francis Galton Francis from Malcom in the Middle

STAND UP AND READ

Francis from Malcom in the Middle, stand up and read your main idea to your table partners.

NOW SWITCH

Francis Galton, stand up and read your main idea to your table partners.

RIGHT PAGE NOTES

•Only write words in RED

Fingerprint Identification

• Print identification is based on the statistical probability that the chances of 2 individuals having the identical ridge characteristics in the same relative position is so remote as to be a practical impossibility.

• AKA: no two fingerprints are the same. – BUT there are some cases where they’re

REALLLLLY CLOSE.

History

• Early uses on earthenware in China (6000 yrs old)

• In King Tut’s Tomb (3000 yrs old)• Used to seal documents (246-210 B.C.)

History

History Cont.• Sir Francis Galton (1892)

– Developed 1st method of classifying fingerprint patterns– Prints are individual and permanent– Wrote Finger Prints

• Sir Edward Richard Henry (1901)– Simplified fingerprint classification by using 10 print card a grouping

prints by pattern type• John Ferrier (1904)

– 1st print instructor in the US, taught 9 students at world fair in St. Louis• Juan Vucetich (1892)

– 1st criminal fingerprint case, Rojas murders, eliminated neighbor and implicated the mother

Important print research

• 1684 – description of ridges, furrows and pores on hands and feet – Dr. Nehemiah Grew

• 1686 – used microscope with prints, wrote of the function as tactile agent – Marcello Malpighi

• 1904 – development of volar pads - Inez Whipple• 1952 – developmental stages of volar pads and

ridges/furrows as a fetus, 12-13 weeks begins completed by 18 weeks – Alfred Hale

Anatomy of the Fingerprint• In a cross section- a

boundary of cells separating the epidermis from the dermis is made up of dermal papillae- these determine the form and pattern of ridges on the surface.

• Dermal papillae develop in the fetus and remain unchanged during life.

How each print forms?• Fetal movement and ridge fusion

TAKE YOUR OWN PRINTShttp://www.youtube.com/watch?v=NA4z3uCQBdM

Take prints from all five fingers of one hand – you choose the hand

Take each print onto a different sticker.

Write your name, the hand (left, right) , and finger (thumb, index, middle, ring, pinky)

Example: Mr. Cater

Left hand

Thumb

CREATE A GRAPHIC ORGANIZER / concept map / flow chart

Must include• The 3 major classes and subclasses of fingerprints• All of the parts of fingerprints• All of your table partner’s fingerprints – in the correct class and

subclass• NEED TO SHOW THE RELATIONSHIPS between everything – it can’t

just be a list.
