Forensic Science

This term for science we have been learning about Forensic science.
Forensic science is the science used by the police and detectives all
around the world to help solve a crime.

We learnt about Locard's Exchange Principle, Fingerprints, fibres,
using Microscopes Making Hands with Cement and chromatography.

My favourite Part was making the cement hands, Mine broke but it
was still fun to make the cement. I worked with Aiden and Ruby.
I really liked it because you could actually see everything forming.
When you mixed the Plaster Of Paris and water together it forms the
cement in seconds. As I was making the cement Ruby poured in a
little too much water and it became very gooey and it didn’t form.
Mrs wheeler then put someone else's cement in ours and it formed the
right cement. I found it really fun even though mine broke afterwards,
I would do it again.

We were also asked to see what fingerprints we had. I have all loops
and no Arches or Whorls.
