The Criminology course has less emphasis on chemistry
It does, however, contain the unit on Forensic Science: Applications that is used in the Applied Science course.
A possible list of suitable contexts and activities is provided in the course documentation and in a chemistry context it includes:
Flame tests (to identify metals)
Flame Colours gives a variety of ways you can do these.
Chromatography (eg of ink or lipstick)
Black Magic Experiment - another simple esperiment involving chromatography.
Melting points (eg to identify a white powder)
Gel electrophoresis (eg of a mix of food dyes)
Reactions of metals (to cover corrosion with oxygen and removal of serial numbers by acid)
pH measurements (eg of soil, of ‘unknown’ liquids)
No significant practical work here.
Again, probably no significant amount of practical work here.
