A dichotomous key is a tool used to identify many things in the Sciences ranging from rock types to leaf/tree species to living organisms such as bacteria. You can google many such keys. It is simply a numbered list of questions, each with a "yes" or "no" answer for each one. Your answer will direct you to the next question in the key until you arrive at the identity of the rock, leaf/tree or bacteria. Many rock identification keys will ask you questions about colour, crystal size, hardness( can it scratch glass or can it be scratched by a nail ), magnetism and its reaction to acid( usually vinegar ). Good luck!
