Wrongfully convicted? A Forensics Investigation

  • - (AEST)
  • Cobram Anglican Grammar School
    Campbell Road, Cobram, VIC 3644, Australia

During National Science week, forensic students will take on the role of forensic scientists to perform forensic based activities. They will analyse DNA evidence from a fictional attempted homicide case involving a suspect known as J.M. Although J.M was convicted and is serving a life sentence, he maintains his innocence. Students will examine newly collected DNA evidence to determine whether he was wrongfully convicted or whether the results implicate him further.

Using our school's existing electrophoresis unit alongside a mini-PCR forensics lab kit (which includes victim DNA, J.M's DNA, two other DNA evidence samples plus a fast DNA ladder) students will learn micropipetting, gel loading and interpretation of DNA banding patterns. The lab supports up to 8 groups of students within a 45-minute class. The scenario demonstrates the power of DNA analysis in modern investigations and aligns with Victorian Curriculum Level 9-10 Biological Sciences content, including 'multicellular organisms rely on coordinated interactions between systems' and 'heredity and DNA as the foundation of continuity and variation'. Students will present findings in a mini-Forensic expo, strengthening communication skills and community engagement.
