  1. DO NOW: discuss with partners for 2 minutes. I often go to the police station, sometimes in the middle of the night, and destroy considerable numbers of fingerprints. I do not, however consider myself a criminal. Who am I?

  2. AN ANSWER I am the custodian at the police station.

  3. REACT !!!!!

  4. R.E.A.C.T. R espect everyone E nter and exit appropriately A ccept responsibility C ooperate with everyone T ake action

  5. Turn to your table and give everyone there a sincere compliment.

  6. Merlin the mover

  7. FIELD TRIP:WAS CANCELED BECAUSE OF WEATHER

  8. QUIZZES I HAVE HAD OTHER PRIORITIES (MOVING); THEY WILL BE GRADED BY PROGRESS REPORTS

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

  10. 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 location • Any other information you think is important Your table can ask me for help ONE TIME. Everyone will get the same grade THIS IS A FORMATIVE ASSESSMENT (5 MINUTES)

  11. GALLERY WALK Left page reflection: Look at 2 other posters • How does this differ from my group’s poster? • How is it similar? • MAKE SOME CHANGES?

  12. LEARNING OBJECTIVE DESCRIBE HOW FINGERPRINTS ARE ANALYZED

  13. How are fingerprints analyzed? • Level 1 is the ridge flow and the layout of the ridges. This can rule out but not convict. • Level 2 is ridge characteristics and placement and this can allow an individual to be matched. • Level 3 looks at the angle of the paths, width, shape, pores, edge contours, breaks, scars and cuts and this can lead to prosecutions.

  14. -Identify characteristics / Minutiae/ Galton Details -Find whether the characteristics match on each print How are fingerprints analyzed?

  15. How many details make a match? • Minutia or Galton Details make up the individuality in a fingerprint • A match is up to experience and knowledge of the examiner but usually 8 to 16 are needed.

  16. Computer software compares the location of these minutiae.

  17. AFIS • The Automated Fingerprint Identification System - a computer system for storing and retrieving fingerprints • Began in the early 1970’s to: • Search large files for a set of prints taken from an individual • Compare a single print, usually a latent print developed from a crime scene • By the 1990’s most large jurisdictions had their own system in place. The problem - a person’s fingerprints may be in one AFIS but not in others • IAFIS—the FBI’s Integrated Automated Fingerprint Identification system which is a national database of all 10-print cards from all over the country

  18. NOTES • Staple or tape these in your notebook – right page

  19. LEARNING OBJECTIVE IDENTIFY CHARACTERISTICS (AKA MINUTIA OR GALTONDETAILS) OF FINGERPRINTS

  20. LEFT PAGE – formative assessment Answer for 7 fingerprints: • Loop, whorl, arch? PLUS the subclass… • Level 1, Level 2, or Level 3 match? • Why? • How many matching minutia? USE THE ACADEMIC VOCAB FROM NOTES I GAVE YOU • Which minutia, and where are they located? PLUS any other relevant details.

  21. LEFT PAGE – formative assessment Check yourself on the column of knowledge

  22. CHOOSE Francis GaltonFrancis from Malcom in the Middle

  23. STAND UP AND READ Francis from Malcom in the Middle, stand up and explain what was EASY and what was HARD about that procedure

  24. NOW SWITCH Francis Galton, stand up and explain 3 THINGS YOU LEARNED TODAY
