  1. 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?

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

  3. REACT !!!!!

  5. Shake hands and state your name to your table partners, and tell them: • Today will be great • I’m ready to learn • Thanks in advance for helping me today • Forensics bros 4 life

  6. FIELD TRIP:CSI Exhibit Witte Museum in San Antonio DATE: Friday 1/24 9 AM – 2 PMCOST TO YOU: $5 + lunch BRING YOUR SIGNED PERMISSION FORM TO ME BEFORE FRIDAY

  7. more PAINT

  8. QUIZZES I WILL HAVE THEM GRADED BY FRIDAY

  9. LEARNING OBJECTIVE Compare the 3 major fingerprint patterns of arches, loops, and whorls, and their subclasses

  10. FINGER PRINTS (5 minutes) • You will read the first two pages of “Finger Prints” by Francis Galton from 1892 LEFT PAGE independentactivity: what do you think is the main idea of this reading? ANSWER IN 2-3 COMPLETE SENTENCES • Underlinewords 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.

  11. CHOOSE Francis GaltonFrancis from Malcom in the Middle

  12. STAND UP AND READ Francis from Malcom in the Middle, stand up and read your main idea to your table partners.

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

  14. RIGHT PAGE NOTES • Only write words in RED

  15. 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.

  16. 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.)

  17. History

  18. 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

  19. 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

  20. 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.

  21. How each print forms? • Fetal movement and ridge fusion

  22. TAKE YOUR OWN PRINTS http://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

  23. 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. Your table can ask me for help ONE TIME. Everyone will get the same grade THIS IS A FORMATIVE ASSESSMENT AND MUST BE TURNED IN TODAY. (25 MINUTES)

  24. GALLERY WALK • FOR TWO DIFFERENT POSTERS, WRITE THIS ON YOUR LEFT PAGE: • How does this differ from my group’s poster? • How is it similar? • DO WE WANT TO MAKE SOME CHANGES?

  25. WELCOME TO ASAP • MULTITASKING: • Come up with a definition with the people at your table. • Be able to do two things OR MORE at once • Doing multiple actions • Being able to balance different activities at the same time • Doing multiple tasks
