Fingerprint Identification Activity (continued)
Activity: Fingerprint Identification and Analysis:
Materials Required:
• Fingerprint ink pads
• Fingerprint cards or index cards
• Magnifying glasses
• Fingerprint Classification Chart
Steps:
1. Introduce the key concepts of fingerprint identification to the students, explaining the basic patterns and minutiae points.
Explain that they'll learn how to analyze fingerprints, just like real forensic scientists.
2. Wash Hands: Clean hands help to avoid smudging fingerprints.
3. Ink the Fingers:
a. Have each student roll one of their index fingers onto the ink pad. Ensure they cover the entire fingertip evenly.
b. Roll the inked fingertip onto a card. This will create their own fingerprint.
4. Analyze the Fingerprint:
a. Examine the fingerprint with a magnifying glass.
b. Use the chart to show examples of fingerprint patterns and discuss the differences between arches, loops, and whorls.
5. Record Data: Have students record observations about their own fingerprints and compare them to others in the group.
6. Clean Up: Properly dispose of used materials and ensure everyone washes their hands to remove ink residue.
7. Discussion: Lead a discussion about the uniqueness of fingerprints, how they are used in real-life scenarios (e.g., forensic
science, law enforcement), and the ethical considerations related to fingerprint collection.
Extend the activity:
To mix things up, choose one fingerprint (at random) and see if students can identify who it belongs to (ensure they initial the
back of cards before you start). Use the magnifying glass to help get a clear view of fingerprint patterns.
