Mrs. McAllister’s 3rd period Forensics class performed the DNA Fingerprinting lab using balloons in an attempt to identify minutiae characteristics and the students’ fingerprint patterns, inducing a curious and stimulating environment.

Students begin their lab by examining their fingerprints using an inkpad.

The first-year forensics students started the lab off by examining their fingerprints on paper by pressing their fingers on an inkpad and carefully rolling their fingers onto a sheet of paper. This required many different tries, for the perfect smudge of ink displaying an accurate representation of their fingerprint was difficult to retrieve.

Forensics students Sydney Chason and Aisha Shariff work together, with Chason holding the balloon, while Shariff applies her fingerprint.

The students then applied their fingerprints onto a balloon before blowing it up. This step of the process required careful attention to obtain an ideal fingerprint to analyze later.

The students were then directed to blow up the balloon and label and categorize their prints. They analyzed the minutiae characteristics, the ridge endings and points of interest in a fingerprint, which then led to the identification of the types of patterns the students possessed.
