Course description

Course DescriptionCourse overview:

Forensics is designed as a third year of college-prep laboratory science for students that are college bound and/or interested in the field of Forensics. This class will introduce students to the field of Forensic Science providing a general overview of the scientific practices involved in solving†crimes.††Students will participate in many qualitative hands-on labs and simulations that develop practical and theoretical aspects of Forensics while developing proficiency in the eight Science and Engineering Practices (SEP) and seven Crosscutting Concepts (CCC)†detailed in the Next Generation Science Standards.
