The first grade scientists studied three kinds of fingerprints. The arch, loop and whorl. They found out that no two people have the same fingerprint arrangement, though they may have a similar type of fingerprint. The class examined their fingerprints with magnifying glasses and compared them to various samples of arch, loop and whorl fingerprints. Next they rolled their fingers in ink and stamped paper for further exploration. Finally they turned their fingerprint into a piece of art!
