Heat vs Fingerprints Science Fair Projects

Temperature

Temperature impacts a lot of things. In this experiment you will determine if it impacts how well a fingerprint is left behind.

Objectives/Goals

Is to determine if you can find a good quality fingerprint when you put glass in the oven, freezer, and rain. I sent the 40 samples to local officers to judgethe fingerprints from a scale of 1-3. 1 being bad to use as evidence.3 being can be used as evidence.

Methods/Materials

-40 glasses
-non-serol gloves
-negative 10 degrees freezer
-200 degrees oven
Latent print feild kit
-dusting brush
-black fingerprint powder
-fingerprint index card
-ink pad
-cutting blade
-tape

Results

Rain on Glass
-overall average of 2.2 out of 3
Heat on Glass
-overall average of 1.1 out of 3
Freeze on Glass
-overall average1.2 out of 3

Conclusions/Discussion

The overall result is that Rain has the best quality and should be used as evidence in a crime scene. Heat had the lowest ratingout of all. 3rd party contributor
