2 ABC Technologies Ms. Susan Greene Plant Products, Inc. Honolulu, Hawaii Dear Ms. Greene: We recently received your letter asking us to test your new plant growth product Magic Spray. We have completed our experiments and think you will be pleased with the results. We decided to test Magic Spray on tomato plants and found that plants whose leaves were sprayed with Magic Spray grew much faster than plants sprayed with plain water. In fact, we were very surprised at the differences we observed. The tomato plants sprayed with Magic Grow grew to a height of over ten inches taller than plants grown without Magic Grow! Enclosed you will find Tables and Graphs which summarize the data we collected while completing our experiments. You also asked us to evaluate the hand-held sprayer that you sent with the Magic Spray. We found the sprayer to be very difficult to use. It often became clogged-up and required constant cleaning to spray a mist of Magic Spray on the plant s leaves. We suggest that you look for a better sprayer to use with your product. Good luck, and thank you for letting ABC Technologies solve your problems. Please feel free to call us again if you need any further assistance. Thank you, Greg Ulmer Carolyn Ulmer 14

10 TRAINING LAB - CLASSIFYING FINGERPRINTS Name Background: You have some things that are yours and yours alone - and NO ONE else on earth has anything exactly like it! They are your fingerprints. Everyone s fingerprints are so unique (even identical twin s prints are different) that a single print can be used as direct evidence to prove that a person was present at a crime scene. Are your fingerprints really that different from everyone else on earth? Let s find out! 1. You will be trained to make an ink print of your fingerprint ridges. 2. You will be trained to recognize the different fingerprint classifications and special ridge characteristics of fingerprints. Fingerprint Reference Information: *your fingerprint ridges are formed during fetal development and NEVER change. *each of your fingers has it s own unique fingerprint ridge pattern that belongs only to you. *Why fingerprints? to make your fingertips rough, which makes it easier to pick up objects. *sweat glands on your fingertips naturally coat your fingerprint ridges with an oily liquid. Every time you touch an object some of these oily liquids are left behind in the shape of your unique fingerprint ridges. *the oily fingerprints you leave behind when you touch objects are called LATENT PRINTS. Latent fingerprints are usually invisible because the oils you leave behind are mostly clear. *latent fingerprints can be made visible by dusting and other methods you will practice in later Training Labs. *latent fingerprints are very important evidence to help identify who was present at a crime scene. *fingerprints are considered an example of INDIVIDUAL EVIDENCE because they are unique to one person or individual. A fingerprint left at a crime scene proves that the fingerprint owner was there. CLASS EVIDENCE is the other kind of evidence that can be found at a crime scene. A shoeprint might be an example of Class Evidence. A size 9 ½ shoe print left at a crime scene can help establish that a suspect was there, but it doesn t prove it. Many people wear size 9 ½ shoes. Procedures: Part 1 - Making A Record Of Your Prints 1. Recording your prints is easy. All you need is an ink pad and a piece of paper. What s difficult is leaving a good record of your prints. Let s practice! 2. Get a piece of blank, white paper and ink pad from the front of the room. Press your right thumb down on the ink pad, then press it on the paper. Make sure you make a print of the CENTER AREA of your thumb not just the very tip. The center area of the thumb contains the part of your print that allows you to identify it. Not getting a CLEAN/PERFECT print? Here are some helpful hints: too much ink on you finger smears the fingerprint ridges on the print too little ink on your finger leaves an incomplete print pushing too hard on the paper smears the fingerprint ridges on the print pushing too light on the paper leaves an incomplete print rolling your finger around on the paper smears the fingerprint ridges on the print 22

11 3. Pick up a blank Note Card and make several perfect right thumbprints on one side (right thumbprints only). DO NOT write your name on this card! 4. Next, pick up a Right Thumbprint Record Form and place FIVE perfect right thumbprints (right thumbprints only) in the boxes along the bottom of the page. 5. Immediately turn in your Right Thumbprint Record Form (with your name) and Note Card (without your name) to your supervisor. 6. Finally, pick up a Fingerprint Record Form and fill out the top of the form. Practice making prints of ALL the fingers on your right hand using blank paper. When you feel you re good enough it s time to move on and make a permanent record of your prints. 7. Place the Fingerprint Record Form on the table so the row of right fingerprint boxes is next to the table edge and the bottom half of the form is hanging over the edge of the table out of the way. Place a perfect right thumbprint in the Right Thumb box, a perfect right index fingerprint in the Right Index box, etc.. 8. Re-adjust the position of the form so the Right Fingers Together box is next to the table edge. Place perfect prints of your four right fingers together at the same time in the Right Fingers Together box. 9. Now place one more perfect right thumbprint in the single, lower Right Thumb box. 10. Repeat Steps 4-6, but this time place perfect prints of your left fingers in the appropriate boxes of your Fingerprint Record Form. 11. Keep your Fingerprint Record Form for Part 2 and 3 of the Training Lab. 12. You should now be finished making prints and can wash your fingers. Part 2 - Classifying Fingerprints/Fingerprint Patterns 1. Fingerprints are classified into LOOPS, WHORLS, or ARCHES based upon the pattern of the fingerprint ridges that are present. LOOPS are further divided into ULNAR LOOPS or RADIAL LOOPS; WHORLS are further divided into PLAIN WHORLS, CENTRAL POCKET WHORLS, ACCIDENTAL WHORLS, or DOUBLE LOOPS; ARCHES are further divided into PLAIN ARCHES or TENTED ARCHES. The appearances of these different patterns can be seen in the Classifications Of Fingerprints pages that follow. 2. Observe the right and left hand fingerprints you placed on your Fingerprint Record Form (use a magnifying glass if necessary) and classify each of your ten fingerprints as a plain arch, tented arch, ulnar loop, radial loop, plain whorl, central pocket whorl, double whorl, or accidental whorl (see the Classifications Of Fingerprints pages that follow for help). Record each print s correct classification in the Fingerprint Classifications boxes found near the bottom of your Fingerprint Record Form. Part 3 - Identifying Special Ridge Characteristics 1. There are also SPECIAL RIDGE CHARACTERISTICS that can be found on our fingerprints. No two fingerprints have the same ridge characteristics located in the same positions. For this reason, identifying Special Ridge Characteristics are very important when matching up fingerprints. Courts usually require ten or more Special Ridge Characteristic matches to prove that a fingerprint found at a crime scene belongs to a suspect. 2. The five most common Special Ridge Characteristics are: ISLAND, SHORT RIDGE, RIDGE ENDING, BIFURCATION, and ENCLOSURE. The appearance of these Special Ridge Characteristics can be seen in the Special Ridge Characteristics page that follows. 3. Observe your prints and find examples of the five different Special Ridge Characteristics. 23

12 CLASSIFICATIONS OF FINGERPRINTS LOOP PATTERNS- Several ridges enter from one side of the fingerprint then fold or curve back and exit from the same side forming a loop. There are two kinds of loops. ULNAR LOOP - if the loop opens toward the little finger it is an ulnar loop. An ulnar loop fingerprint taken from a right finger will open to the right side of the print, an ulnar loop fingerprint taken from a left finger will open to the left side of the print. from a right finger from a right finger right hand loop opens toward the little finger! RADIAL LOOP - if the loop opens away from the little finger (toward the thumb side of the hand) it is a radial loop. An ulnar loop fingerprint taken from a right finger will open to the left side of the print, an ulnar loop fingerprint taken from a left finger will open to the right side of the print. from a right finger from a right finger right hand loop opens away from the little finger! 24

13 WHORL PATTERNS These fingerprint patterns have ridges that form circles or are a combination of two patterns. There are four kinds of whorls. PLAIN WHORL - ridges form a series of complete circular rings or ovals in the center of the print. CENTRAL POCKET WHORL looks like an ulnar or radial loop, but some of the ridges in the center form complete circles. DOUBLE LOOP - ridges form two loops turning around each other. ACCIDENTAL WHORL - ridges form a combination of several patterns. The most common is a double loop with a complete circle or two in the center. 25

14 ARCH PATTERNS - All ridges move across the fingerprint from one side to the other side and rise in the center like a wave. There are two kinds of arches. PLAIN ARCH - a smooth, slightly raised arch. TENTED ARCH - a spike-like ridge pushes the arch up abruptly (like a tent pole holding up a tent). SPECIAL RIDGE CHARACTERISTICS Ridge Ending a long ridge comes to an end Bifurcation one ridge splits to become two Short Ridge a short ridge by itself Enclosure ridge splits, then comes back together Island a dot-like ridge by itself 26

17 Questions Classifying Fingerprints NAME 1. What is the classification of the large RIGHT thumbprint below? 2. Find a bifurcation on the large print below (see Special Ridge Characteristics in your Training Lab for help) and color it with a red colored pencil to make it visible. Also find and color an enclosure, short ridge, island, and ridge ending. Neatly label each of your colored Special Ridge Characteristics. 3. Identify the classifications of the following RIGHT fingerprints. 29

18 4. Why do humans have fingerprints?? (it is not to help with identification!) 5. Get together with several other students and compare your fingerprints. Which fingerprint classification appears to be the most common? Which fingerprint classification appears to be the second most common? Which fingerprint classification appears to be the least common? 6. The fingerprint below has been divided into four sections. Color (with a red colored pencil) one obvious Special Ridge Characteristic in each section. Neatly and accurately sketch (in the provided circles) an enlarged view of the Special Ridge Characteristic you colored in each section. You DO NOT need to include all the surrounding ridges in your sketches. Identify the Special Ridge Characteristic you sketched in each circle. 30

19 ENTRY EXAM SCHOOL OF FORENSIC SCIENCE NAME Instructions: 1. Pick up a Fingerprint Evidence Card from your supervisor DO NOT WRITE ON THIS CARD. These prints were recently left behind at a crime scene and came from the right thumb of the criminal. 2. Write the Evidence Number for the card on the Police Report Form below. 3. Identify the Classification of the evidence print (plain arch, ulnar loop, etc.) and record this Classification in the Police Report Form. 4. Identify who the evidence fingerprint belongs to by looking through the suspect s Right Thumbprint Record Forms currently on file. Always make sure you locate matching Special Ridge Characteristics to be sure you have identified the correct suspect. 5. Write the name of the matching suspect on your Police Report Form. 6. Return the Fingerprint Evidence Card and have your supervisor check your Police Report Form to see if you arrested the correct suspect. 7. Repeat the above procedures with a second and third Fingerprint Evidence Card. 8. GOOD LUCK! POLICE REPORT FORM Evidence # Classification of Print Suspect To Arrest Score Print 1 Print 2 Print 3 31

20 TEACHER NOTES Lab/Activity: Training Lab Classifying Fingerprints Equipment To Prepare: 1 black inkpad/group sheets of white paper (for students to practice fingerprinting) 1 white, 3 x 5 note card/person (for the unknown/evidence thumbprints) 1 magnifying glass/person or group class set of red colored pencils for students to color the special ridge characteristics present in Question #2 Classifying Fingerprints Questions. How to Prepare For The Activity Entry Exam School Of Forensic Science 1. Encourage students to have you check their practice prints, their prints on the Fingerprint Record Form, their prints on the Right Thumbprint Record Form, and their Thumbprint Note Card to make sure they are making good prints. It s no fun telling students they need to make another set of prints after they have already washed the ink off their hands. 2. As students complete Part 1 of the Training Lab they will be asked to turn in to you their Thumbprint Note Card and Right Thumbprint Record Form. Check each Note Card to see that at least some of the thumbprints are clear and that a name has NOT been written on the card students may need to complete another card if necessary. Immediately attach the student s Thumbprint Note Card to their Right Thumbprint Record Form with a paper clip (the Note Card must remain with the Form as there is no name on the Note Card). You MUST collect all Note Cards and Right Thumbprint Record Forms by the end of Day 1 as you will need these items to help you prepare for the Entry Exam School Of Forensic Science Activity introduced on Day You can give students the Questions Classifying Fingerprints page to begin working on during Day 1, or you can wait until the start of Day 2. However, it is helpful if students complete the Questions BEFORE they begin the Entry Exam School Of Forensic Science activity (they introduce students to Special Ridge Characteristics). 4. Before students can begin the Entry Exam School Of Forensic Science activity on Day 2 you must do a little organizing. You will need to look through the Right Thumbprint Record Forms AND attached Note Cards and pull out the sets with the best/clearest thumbprints (you could do this as students turn their Form and Card in to you on Day 1, if possible). Remember to keep each Form and Card attached together. Collect a pile of 30 to 35 of the clearest/best thumbprints from among all your classes. ALSO - As you pull out the best thumbprints you should select examples of all eight print classifications (at the end of the day we usually end up with something like 8-10 ulnar loops, 0-1 radial loops, 5-6 plain whorls, 5-6 double loops, 5-6 central pocket whorls, 3-4 accidental whorls, 1-2 plain arch, 1-2 tented arch that we have selected). Place the Right Thumbprint Forms and Note Cards that you are NOT using out of the way, however, don t throw them away they are good sources of fingerprints that you might use for other activities. 32

21 5. Make a copy of the blank Thumbprint Identification List that follows. Choose one of the Right Thumbprint Record Forms from your pile of best/clearest thumbprints and write this student s name next to Student ID #1 on the Thumbprint Identification List - then write the number 1 on this student s attached Thumbprint Note Card. Continue filling in the Thumbprint Identification List with the names of students whose Right Thumbprint Record Forms you have chosen to use and correctly number their attached Thumbprint Note Cards to correspond with their Student ID Number (Note Card #1 should belong to the first student on the list, Note Card #2 to the second student on the list, etc.). All this could also be completed as students are turning in their Forms and Cards to you on Day 1, if possible. 6. Now that the Thumbprint Note Cards have been numbered (and can be identified by this number) you can separate them from their Right Thumbprint Record Forms and place them in a pile ready to be used. Label eight folders, each with a different fingerprint category name (Ulnar Loop, Radial Loop, Plain Whorl, etc.). Place each selected Right Thumbprint Record Form into its correct folder based on its classification. 7. On the day we begin the Entry Exam School Of Forensic Science activity (Day 2) we take the selected Right Thumbprint Record Forms out of their folders and spread them out in different labeled locations around the room all the Ulnar Loops in one location, all the Double Loops in one location, etc.. This gives the students room to spread out as they work. The Right Thumbprint Record Forms you spread out will represent a database of suspect s thumbprints on file. You should also have magnifying glasses available for students to use as they look at the thumbprints. 8. Pass out the Entry Exam School Of Forensic Science activity to students and be prepared for non-stop action. As each student comes to you, you will need to give them one of the numbered Thumbprint Note Cards (this will represent fingerprint evidence left behind at a crime scene). A student will try to identify who committed the crime by comparing the Note Card thumbprint with the prints on the Right Thumbprint Record Forms. Eventually, the student will bring you their Police Report Form with their suspect s name written out. You can quickly check to see if they are correct by looking at your Thumbprint Identification List - check to see if the Evidence # (the # on the Note Card) matches up with the suspect they have written down to arrest. 9. We give students three tries to get a correct match. If they get it right the first time they earn 10 points. If it takes them two tries to get a correct match they earn 5 points. Three tries to make a match is worth 2 points. 10. When a student makes a correct match they will exchange their old Note Card for a a new Note Card to analyze (each student will analyze three Note Cards before they are finished). Try to give students a different classification of print each time they get a new Note Card from you. 11. When a student has correctly arrested their three suspects collect their paper, shake their hand, and congratulate them as you tell them they have been accepted into the C.S.I. School Of Forensic Science! 33

22 Comments/Problems: This lab usually takes 2 days to complete. Complete Part 1, 2, and 3 on Day 1. Questions on Day 1 or Day 2, and Entry Exam School Of Forensic Science on Day 2. The biggest problem students have making prints is pushing down on the paper too hard and smearing their print. These students will have much better results if they lightly touch the paper and immediately lift their finger. Another problem is that students only touch the paper with the tip their finger. This may leave a good print, but does not show the part of the print needed for identification. Have them place their paper near the very edge of the table so they can hold their finger out flat and get a print from the area between the first joint and the tip of the finger. Warn students that they will probably have dirty fingers when they are finished! I don t think we have ever had any students refuse to make ink prints. If you have a single, small class you may not end up with enough Right Thumbprint Forms to make the Entry Exam School Of Forensic Science activity challenging. Simply gather more prints from student volunteers in your other classes or from other teachers. You can make the Entry Exam School Of Forensic Science activity more challenging by adding more Right Thumbprint Forms and Thumbprint Note Cards (more than the recommended 30-35). This forces students to look through more suspect prints to find a match to their evidence print. You can use the same Thumbprint Note Cards and Right Thumbprint Record Forms from year to year, however, students seem to enjoy working with prints of students they know. We make new sets every year but fill in where needed with older Note Cards and Forms (usually Radial Loops, and Arches). One of our favorite stories comes from a very capable student of ours that misidentified their own fingerprint twice! 34

26 TRAINING LAB SOLVING A CRIME WITH BRAIN POWER NAME Background: To solve successfully crimes you will learn to use many new tools and skills, however, the most important tool you will use is something you carry with you your brain! Solving a crime often involves using your brain to organize and piece together many bits of collected information or evidence. Brain power is then needed to analyze and make sense of all this information to reach a conclusion and hopefully solve the case. The only way to sharpen your brain and make it more efficient is to use it! So, let s get right to work using this special tool of yours to analyze some information and help solve a crime! Procedures: 1. Read the crime scenario below, then use the information given to you by the police to help solve the crime. Table 1 is an Organization Grid to help you analyze the information you receive from the police. When you think you have correctly solved the crime you should write your final conclusions in Table 2. THE CRIME SCENARIO Five men were recently arrested for robbing a local bank and are now being held at the police station. The criminals had apparently made their way in to the bank s vault just as the alarm sounded. Each man quickly reached into a different cash drawer and grabbed out some money. The bank always places different denominations of money in separate cash drawers, therefore, one man grabbed out a bag of only $1 bills, another a bag of $10 bills, another a bag of $20 bills, the fourth a bag of $50 bills, and the last man grabbed out a bag of $100 bills. The police quickly surrounded the bank and the five men surrendered, walking out of the bank with their hands up. The five bags of money were found on the floor of the bank lobby and the cash drawers were dusted for fingerprints. A different thumbprint was discovered on each of the five cash drawers. The police questioned the criminals to gather the facts, however, the five men did not cooperate and gave out only small bits of information. Before the five criminals can be successfully prosecuted in court all the events and facts related the crime must be stated correctly, and at this point in the investigation everything seems to be in a mess. You, the forensic expert, have been called in to sort things out! Using the evidence and information provided by the police, correctly determine each robber s FIRST and LAST NAME, the BILLS THAT EACH MAN GRABBED, and the FINGERPRINT THAT BELONGS TO EACH MAN. 38

27 Police Information #1 Tim (who does not have a double loop thumbprint), Larry, Ryan, Mr. Johnson, and Mr. Won had been friends since High School. Police Information #2 Tony grabbed larger bills than Mr. Smiley, Ryan, and Mr. Brown (who grabbed the smallest bills), but Tony grabbed smaller bills than John. Police Information #3 Mr. Johnson has a thumbprint that is not a whorl or a loop, while John and Mr. Smiley have the prints that belong to the Whorl Classification. Police Information #4 The man with the ulnar loop grabbed the smallest bills, while the man with the radial loop grabbed the third largest bills. Police Information #5 The men with the last names that are colors all have thumbprints that belong to the Loop Classification. Police Information #6 Ryan did not grab the $1or $10 bills but Larry, the guy with the plain whorl, did manage to grab the $10 bills. Table 1 Organization Grid Use the grid below to help you organize information. Put a in a box to indicate a correct connection between information and an X in a box to show connections that you know are not correct. Fingerprints collected from the five cash drawers.

29 TRAINING LAB - HOW TO LIFT FINGERPRINTS NAME Background: When you touch an object an invisible fingerprint image is usually left behind, formed from the oils and sweat that are produced by glands found on the raised ridges of your fingerprints. These invisible prints are called LATENT PRINTS and are an important tool in Forensic Science. Latent prints can be made visible using various techniques, lifted or photographed, and used as Individual Evidence to prove that a suspect was present at a crime scene. Some techniques used to make Latent Prints visible are: Clear or Light Colored Hard Surfaces use dark powder to lightly dust the print Dark Colored Hard Surfaces use a light-colored powder to lightly dust the print Metals and Plastics develop the print in Cyanoacrylate (Super Glue) fumes Paper dust with dark powder, develop the print with Iodine fumes, or spray the print with Ninhydrin (we will not be using Ninhydrin in this lab) 1. You will be trained to dust and lift latent prints from hard surfaces. 2. You will be trained to dust and lift latent prints from paper. 3. You will be trained to develop latent prints on paper using Iodine fumes. Procedures: Part 1 Dusting and Lifting Prints From Glass or Plastic 1. Each person should pick up a clean, dry, glass slide. 2. Lay the slide on the table and place a good thumbprint in the center of the slide. You might leave a better print if you first touch your thumb to your face, or oiled sponge, to pick up extra oils. Don t press too hard on the slide or roll your thumb or your print will smear. You can always clean your slide and try another print if needed. 3. IF USING MAGNETIC DUSTING POWDER AND MAGNETIC BRUSH CONTINUE HERE: A. Lay the item to be dusted (glass slide) on a piece of white paper. B. Keep the plunger of the magnetic brush pushed down and pick up a beard of magnetic dust so that it hangs from the brush bottom. C. Gently brush the hanging beard of magnetic dust over the latent print(s) you want to lift. DO NOT let the plastic brush touch and smear the print. You can also pull the plunger up to release the magnetic dust on top of the print, then push the plunger back down and pick up all the loose dust. D. Use the magnetic brush to carefully collect ALL the excess dusting powder and release it back into the powder container. Keep your dusting station clean. Thank you! E. The latent print(s) should now be visible the ridges covered with a thin layer of dust. 3. IF USING REGULAR DUSTING POWDER AND BRUSH CONTINUE HERE: A. The dusting powder is VERY messy please be neat. Thank you! B. Lay the item to be dusted (glass slide) on a large piece of paper, or in a tray. C. Touch the tip of the dusting brush to the dusting powder to pick up a little powder. D. Lightly swirl the brush over the latent print, but be careful dusting too hard can smear the print. Tap the slide on the paper (or in the tray) to remove excess powder. E. The latent print(s) should now be visible the ridges covered with a thin layer of dust. 4. Time to lift the print!! Get a piece of tape long enough to fit over the entire print. Stick one end of the tape on the slide near the print, then use a thumb to smooth the rest of the tape over the print. Make sure the tape has stuck tightly to the slide and print. 41

30 5. Slowly peel the tape from the glass slide. The print should lift with the tape. Stick this lifted print in the Lift #1 rectangle found in Part 1 of your Data Table. 6. Clean your slide and repeat steps #1 - #5 a second time. This time place your lifted print in the Lift #2 rectangle. 7. Have your Supervisor check your two lifted prints. If they are of good quality you can move on to Part 2 of the Training Lab. Otherwise, continue lifting prints #3, #4, and #5 until you can lift a quality print that is easily identified. Part 2 Dusting and Lifting Prints From Paper 1. Pick up a half-sheet of blank white paper. 2. Touch your right thumb to your face, or oiled sponge, to pick up oils, then put several good, right thumbprints on the paper (your prints may NOT be visible on the paper). 3. Dust and lift TWO latent thumbprints from the paper using the same method you used for dusting and lifting from glass. 4. Place your lifted prints on your Data Table in the Part 2/Lift #1 and #2 rectangles. 5. Have your Supervisor check your two lifted prints. If they are of good quality you can move on to Part 3 of the Training Lab. Otherwise, continue lifting prints #3, #4, and #5 until you can lift a quality print that is easily identified. Part 3 Developing Prints From Paper Using Iodine 1. Pick up a small square of blank white paper. 2. Touch your right thumb to your face, or oiled sponge, to pick up oils, then place a good right thumbprint in the middle of the paper square. Carry the paper square by its edges to an Iodine Developing Station. CAUTION * Don t touch the iodine crystals in the container. * Open and close the container quickly so fumes won t escape. * Don t breathe the iodine fumes. 3. Pick up your paper/print with forceps, open the lid to the developing container, quickly place your paper inside, and place the lid back on the container. 4. Allow the print to develop in the container for about 1½ minutes. Iodine crystals in the container will turn into Iodine gas, which will stick to the oils in the latent fingerprint and turn the fingerprint a brown-orange color. When time is up, quickly remove the paper from the container using forceps. Be sure to replace the lid on the container! 5. If your print is not visible you may need to try again from Step #1. 6. Unfortunately, an Iodine-developed print is not permanent and will eventually fade away. For this reason, a photograph is usually taken of the print. 7. An Iodine-developed print can t be lifted from the paper. Tape your developed print/paper directly on your Data Page in the Part #3 rectangle. 8. Wash your hands after developing prints with iodine.
