Did you know that no two people have exactly the same fingerprints? Fingerprints help identify people and are used by scientists, law enforcement, and even the technology we use every day. Fingerprints are one type of biometric, a unique physical characteristic that can be used to recognize a person. In this Mini Spark, you will learn about fingerprints and discover how biometrics are used in the modern world.

1. Set up your Science Mini Spark recording page: #43: Fingerprints. Answer this questions: Why do you think every person has different fingerprints?
2. Watch this video. How do the different patterns of fingerprints get started?
3. Create a Fingerprint Mini Dictionary.
Choose at least 8 vocabulary words from the video.
For each word, include:
- The term
- A definition in your own words

Example:
Fingerprint
The pattern of ridges on the tip of a finger that is unique to each person.
4. Biometrics are physical traits that can be used to identify a person. Examples include:
- Fingerprints
- Facial recognition
- Iris scans
- Voice recognition
Record these on your recording page. Next to each on, think of a real life example of when they would be used. When you are done, scroll to the bottom of this post to see some suggested answers.
