What is the scientific method and how is it applied to criminal investigation by investigators? A:The scientific method is a procedure of asking and answering questions by making observations and by doing experiments. The scientific method is used by criminal investigators to determine who, how, and why the crime has occurred. The steps to the scientific method is to first ask yourself questions to what you are trying to determine. Second is to do the research of the facts that you have. Third is to create an idea of how you think the crime happened.

The fourth step is to test your idea by creating experiments. The fifth and final step of the scientific method is to examine your data from the experiments and come to a conclusion. 4.
