Reaction kinetics is a fundamental chemistry concept that can be challenging for many students. This forensics-themed investigation offers an engaging, sustainable approach to teaching reaction rates. Students gain hands-on experience determining reaction order and rate laws while solving a fictional crime scene scenario. From general high school chemistry through AP Chemistry and introductory college courses, this investigation demonstrates—and tests—concepts like reaction order, rate constants, and half-life calculations. Vernier chemistry specialist Nüs Hisim demonstrates how to use sensors you may already have in your lab to help students connect mathematical analysis to real-world applications.
