### Fingerprinting Slides

1. 1. Fingerprinting With Math<br />Lindsay Turner<br />CIS 350<br />
2. 2. Questions for Thought…<br />Have you ever been fingerprinted?<br />How do you get a fingerprint?<br />Why do you think we fingerprint?<br />What other types of identification do we have?<br />What jobs would deal with fingerprinting?<br />How many people have the same exact fingerprint as you?<br />
3. 3. Types of Fingerprints<br />Each person has an unique set of fingerprints. <br />No two people in the world share the same fingerprint.<br />Fingerprints are separated into different categories. <br />Within each of these categories there are different types.<br />For the purposes of our class, we are only dealing with four different classifications.<br />Let&apos;s try matching some fingerprints!<br />
4. 4. What are the differences in these fingerprint types?<br />
5. 5. What are we going to do?!<br />Soon, we will break into our groups and start fingerprinting each other.<br />First we need to put something on your finger to capture the print.<br />What are some things we can use?<br />For our class, we are going to use our pencils.<br />Take your pencils and rub them onto your paper. <br />Then, rub your finger into the scribble that you have made.<br />
6. 6. Capturing Your Fingerprint<br />After your finger is coated with the pencil residue, a student in your group will smooth a piece of tape on your finger.<br />Once you pull the tape off you will see your fingerprint. Hold it up the light and decide which type of fingerprint it is.<br />When everyone in your group comes to a consensus place your tape beside the corresponding fingerprint on your worksheet.<br />Do this for every member of your group.<br />
7. 7. Analyzing the Data<br />Now that you have determined the types of fingerprints in your group, you can put the data into a pie chart.<br />What is beneficial in putting information into a graph?<br />Each person will fill in their own pie chart on the bottom of their worksheet.<br />After everyone in your group has finished, you will compare graphs and check your work.<br />Finally each group will make a large graph on their poster board to preset to the class.<br />
8. 8. After each group explains their pie chart to the class, we will then compile the information to make a pie chart for the entire class.<br />
9. 9. At the End of Class…<br />Fill in the class’s pie chart on your worksheet.<br />Then, each student is responsible for creating their group’s pie chart using Microsoft Excel.<br />Tomorrow…. We will be collecting fingerprints from our crime scene.<br />
