Experiment Title: Observation of Hair, Nose, Hand, and Clothes Effects on Fingerprinting
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: The purpose was to see what type of surface was better for making fingerprints.
What was your hypothesis?: My hypothesis was that clothing would be the best, hair would be the second best, and nose and hand would be the third best.
What materials did you use in your experiment? List them all.: 1. Flour
2. Clothing
3. Nose
4. Hair
5. Hand
6. Finger
7. Tray
8. Cup
9. Paintbrush
10. Fingerprint pad
11. Tape
12. Chart
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: 1. Get the materials.
2. Make your hypothesis.
3. Put one of your fingers on the back of your hand.
4. Put your finger on the pad and press.
5. Put flour on your paintbrush and do circle movements on the pad with the fingerprint.
6. Put tape on your fingerprint, rub it smooth. Take it off and put it on your chart.
7. Repeat for other surfaces using a different finger.
What were the results of your experiment?: The results for our experiment were: nose helped make the clearest fingerprint, hair was two, hand was three, clothing was four.
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?: I learned that skin oil is better at making fingerprints than any other surface we tested.
