The Crime Scene Investigation (CSI) activity is a component event of Karnival Jom Sains 2026 (KJS 2026), designed as an interactive platform for secondary school students to experience the role of a forensic investigator. Participants will engage in solving a simulated crime using scientific principles from Physics, Chemistry, and Biology, enhancing their critical thinking, analytical skills, and understanding of real-world forensic applications.

Through CSI, participants will analyze evidence, identify suspects, and solve mysteries using scientific investigation methods. All necessary materials and equipment will be provided by the organizers. Certificates will be awarded to all participants, and limited slots are available on a first-come, first-served basis.
