Introduce your budding forensic scientists to the many types of impressions taken at a crime scene and how they can lead to solving a crime. Investigators at a crime scene must be extremely careful not to destroy any trace evidence that may lead to a suspect, and in this activity, students will learn how to observe, classify, and analyze impression evidence. They will look at footprints, fingerprints, writing, rope and binding, and key impressions, as well as tire tracks. They will also be able to make casts of the various impressions to help solve the included crime scenario. The activity comes with enough materials for six setups, as well as instructor, student, and assessment manuals.
