Fingerprints
Zoology is a study about people and animals.
Fingerprints are grooved patterns on the tips of the fingers. Everyone’s fingerprints are different, so they can be used for identification.
Purpose: To discover how these variables affect fingerprint patterns:
* Different fingers on the same hand.
* Fingers on right and left hand.
* Different family members.
Clues: How to collect fingerprints.
1.Press your finger against an ink pad or mark on a piece of paper with a pencil and rub your finger tip across the marking.
2. Press the sticky part of a piece of transparent tape across the colored part of your finger.
3.Remove the tape and stick it to a piece of white paper.
How to Identify Fingerprints
Compare collected fingerprints to the three basic patterns shown here.
The ridges and valleys of fingerprints form three basic patterns: loops (left), whirls (center), and arches (right).
