We learned about Dactyloscopy or Dactylography (the study of fingerprints) during Project Lab. We used Model Magic to make a fingerprint model to look at and examine. We then took flour to make a more visible print to study. Our final activity was to use an ink pad to make a copy of each of our fingerprints. Students used a guide to discover and label the different patterns they found. Third grade students shared their findings with one another. They thought it was really cool that even identical twins have their own unique prints.
