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.

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.
