Dental Forensics
-
Create a dental impression by cutting a Styrofoam plate into six equal wedges. Stack two wedges, then cut off 1 inch from the pointy edge. Place the stacked wedges as far back in the mouth as possible, then bite down firmly and analyze the characteristics of the teeth.
Hair Analysis
-
Forensic investigators often view hair samples found at the crime scene. Use a microscope to analyze hair characteristics from friends. Look for distinguishing characteristics such pigment, texture and thickness.
Fingerprint Identification
-
Since sometimes complete fingerprints are not available at crime scenes, scientists analyze partial prints for patterns and consistencies. Conduct an experiment about fingerprints by comparing prints in family members.
Bloodstain Pattern Analysis
-
Bloodstain pattern analysis refers to the properties of blood, how it falls and how it splatters. By looking at blood patterns, investigators can determine many things about the crime. Create your own experiment by studying how a liquid such as chocolate syrup is affected by projection, surface texture or quantity.
