Transcript of Kristina's Project
-Magnifying Glass Data and Graphs Procedure Are Fingerprint Patterns Inherited? Step 1-Use the moist towelette to clean your first volunteer's right index finger. Step 2-Dry the finger with your paper towel.
Step 3-Put their finger on the ink pad until their whole finger is covered with ink.
Step 4-Press their finger in a circular motion on the white paper with very little pressure.
Step 5-Leave the finger on the paper for at least 5-7 seconds then release the finger.
Step 6-After that use the moist towelette to clean the finger.
Step 7-Repeat steps 1-6 on three other volunteers (same finger) (all related)
Step 8-Use the magnifying glass to compare the patterns.
*Keep ink pad away from children under the age of 6.
*Keep magnifying glass away from children also under the age of 6. Materials Kristina Serrano
5th Grade After doing my experiment I found out that fingerprint patterns are inherited. Each pair of people I tested had the same category of fingerprint patterns. The thing that I learned while doing this project is even though fingerprint patterns are inherited the pattern won't be in the exact same place. If I could change my project I would've done my tests on twins. The Materials I Used Whorl Pattern Loop Pattern Arch Pattern Thanks For Listening! The whorl pattern has its ridges in a circular shape. The loop pattern has its ridges rise up from one spot and end the same way it entered. The arch pattern has its ridges enter from one side,make a rise in the center and exit on the opposite side. Purpose *The purpose of my project was to find out if fingerprint patterns are inherited. I chose this topic/question because I want to learn more about fingerprints and if they are inherited or not. Hypothesis * I think that fingerprint patterns are inherited. I think this because based on my background research I found out that the patterns are based on personal characteristics and traits. Also if you are left hand or right handed or the color of your eyes. Another reasoning is that I've heard people say that they're inherited but I want to prove it myself. Words to Know
and Research *Gestation [je-stey-shuhn] - The development of something or someone.
*Epidermis [ep-i-dur-mis] - The outer nonsensitive and non vascular layer of your skin.
*DNA [D-N-A] - The set of non genetic traits, qualities, or features that characterize a person or thing.
*Genetics [juh-net-iks] - The science of heredity, dealing with resemblances and differences of related organisms resulting from the interaction of their genes and the environment.
*Inheritance [in-her-i-tuhns] - The genetic characters transmitted from parent to offspring, taken collectively. Background
Research *During 10 through 24 weeks of gestation, ridges form on your epidermis. The pattern on your epidermis is known as your fingerprint. Finger-print patterns don't change by age so a person will have the same pattern from childhood to adulthood. The pattern may change it's size but not it's shape so for example when you are in your teenage years your fingerprint size may have a different size when you are older. Finger-prints can be grouped into 3 categories. There is the whorl pattern, the arch pattern, and the loop pattern. The DNA people inherit from their par-ents determine many other personal character-istics and traits, like whether someone is right or left handed or the color of their eyes.
