Did you know that no two people on this whole planet have the exact same fingerprint. There are three types of fingerprints loops, whorls and arches. Some fingers have both types.
In our My C.S.I class we have learnt a lot about how the forensic scientists do things, fingerprinting, DNA samples, hair, fibre, chromotograghy, bones, blood types and blood splashes ,
Did you know that the average adult body has 206 bones. When a baby is born they will have about 300 bones this is because as they grow older the bones will merge together to form one.
