High School: Chemistry – Forensics (Bioscience)
Chemistry: Forensics is an inquiry-based laboratory course that emphasizes essential concepts with real world
applications and forensic science as the over-aching theme. Students will explore topics such as structure
of matter; molar relationships; gas laws; chemical reactions; qualitative analysis; acid/base reactions; and
