exit ticket

The materials I used include, black fingerprint powder, fiberglass brush, regular camel hair brush, glass beakers, clear tape, a notecard, and my fingerprints.

To begin, I gathered oil from places onto my finger , then I pressed my fingerprint on to the glass beaker.  After that, I used the fiberglass brush and camel hair brush to wipe the fingerprint powder over the fingerprint.  I then got tape and put it over the fingerprint, then I slowly, and carefully pulled off the tape. When I was done pulling off the tape, I placed the tape on the notecard and examied it.
