This is a great lab for high school or even middle school chemistry.
It is a "beefed-up" version of your traditional white powder lab that has been used in chemistry class.
Rather than just testing white powders, students must analyze the results from the white powder tests and use them to identify a mixture of white powders that links a certain culprit with a crime.
It's a great lab for both utilizing the use of the scientific method as well as the properties of matter!!
I've included some sample data as well as some signs that can be placed at each lab station clarifying directions.
