This resource focuses on Locard's Exchange Principle, which posits that whenever two objects come into contact, physical material is transferred between them, described as 'every contact leaves a trace.' The learning objectives aim for students to identify evidence transfer at crime scenes and analyze simple scenarios to explain cause-and-effect relationships. Key terms such as evidence, transfer, trace, and contact are defined for better comprehension. Activities include guided practices where students engage with examples of evidence transfers in real-world scenarios and utilize structured sentence frames to articulate their understanding. Students also explore forensic concepts through fiber analysis, evidence matching, tool mark uniqueness, and biological evidence analysis, reinforcing key principles of forensic investigations and the importance of evidence preservation.
