Investigate alternate methods for lifting fingerprints while practicing the scientific method.
Students will gather data using fingerprint evidence as they observe, compare, contrast, and hypothesize their way through four different experimental procedures. They will learn how to make impressions in clay and pour a mold, lift fingerprints from a metal soda can using super glue fuming, and use both iodine and ninhydrin fuming to lift fingerprints from paper. The activity includes enough materials for six setups, an instructor’s manual, an assessment manual, and student data sheets. Note: The lab should be performed under a chemical fume hood.
