This learning resource involves a case file called 'The Mysterious Backpack' where students are tasked with investigating a found backpack containing a grocery store receipt and an expired gym pass. They must use forensic methods to analyze the evidence, make connections, and understand the implications of their findings. The activity encourages critical thinking and problem-solving as students reflect on the evidence collected and explain the behaviors that can be inferred from it. Additionally, the resource includes sections for self-assessment of confidence in forensic skills and an invitation to explore further learning in forensics.
