Fingerprints

Question: Is your right thumb Print and your left thumb print identical? 

Hypothesis: We predict that our right and our left thumb prints are both different from each other.

Our science experiment

Materials: 

<List of Materials>

    . Index Card

• wipes
• magnifying glass
• ink

---

Safety Procedures

. wipe your hands after touching the ink
.​Treat the magnifying glass with care so you do not break it.
.Do not use the magnifying without instructions

• do not touch the magnifying glass with ink 
• wipe your hands well

               Procedure

           steps for our experiment

1. Get all materials needed for the experiment
2. take the  ink and rub your finger against it until your thumb is fully covered with ink
3. press your thumb down on the index card
4. wipe your hands well
5.  do the same procedure except with your left thumb instead of your right
6. after you have done that take the a magnifying glass
7. after that observe to see what kind of pattern it is
8. then take your left thumb and repeat step 7

The Science behind it

    Our project is about finger prints. A fingerprint is a narrow impression left by friction ridges of a human finger. Fingerprints usually form 10-15 weeks. Fingerprints are used for identifying people. There are 3 different types of fingerprints one is a Arch, another is a Loop and the last one is a Whorl. There are 4 different types of arch patterns , 2 different types of loops and 4 types of whorl. A arch is found 5% of fingerprints encountered, they are formed when the Volar pad is nearly absorbed, then the finger will develop a arch pattern. A  loop is found in 60-70% of fingerprints encountered, loops are formed by if primary ridges appear while the volar pad is less pronounced  then it will develop a loop. A whorl is seen about 25-35% fingerprints encountered. They can be formed by if the primary ridges appear while the volar pad is still quite pronounced. Most fingerprints  you get are, inherited from family members but their child's fingerprints are  going to be different, from their parents. 

Conclusions

  In  conclusion we accept our hypothesis  because our hypothesis was right. We noticed when we were looking at our fingerprints and we saw that our right and left thumb print were different from each other,but they were similar. They were similar because they were the same type but different kinds of loops, arch and whorls. They were different because they had different lines and shapes also the types of fingerprints were in different spots.
