tool for use in a follow-up activity. Time: 60-80 minutes Introduction: With the blood spatter activities (Part I alone or Part I and II in combination)‚ students will generate a field guide for later use (e.g. during a lab exam or for the analysis of a cold case). Asking students to create a guide that they know they will have to rely on for an upcoming activity often enhances the quality of the outcome. The guide can be developed in the form of: graphs only with descriptive captions.

Conditions That Can Affect Blood Results Using Luminol The purpose of this science experiment was to discover under what conditions can blood give a false result using the presumptive test called luminol. In order to better grasp the experiment‚ research was conducted on several subtopics: the basic concept of luminol‚ the basic concept of artificial blood which is being used for this experiment instead of legitimate blood‚ and substances interferences that could tamper with crime scene results
