How do fingerprint analysis and various lifting techniques contribute to forensic investigations and the solving of crimes?
Collaboration: Working with peers to practice fingerprint lifting techniques fosters teamwork and cooperation.
Learner’s Mindset: Engaging with a police officer to understand professional experiences in fingerprint analysis encourages openness to real-world learning opportunities.
What are the key patterns and minutiae in fingerprints that aid forensic experts in identifying individuals, and why are these features significant?
How are fingerprints deposited at crime scenes, and what factors influence their detectability?
What are the advantages and limitations of different fingerprint lifting techniques (such as black powder dusting, UV powder dusting, fuming, and magnetic powder)?
Students will identify and categorize fingerprint patterns and minutiae, understanding their role in personal identification and forensic analysis.
Students will demonstrate the process of rolling fingerprints using ink and explain how fingerprints are left behind on various surfaces.
Students will apply multiple fingerprint lifting techniques, critically assessing the effectiveness and applicability of each method in forensic settings.
Assessment Options:
Practical Application: Students will roll their fingerprints and then use various lifting techniques to collect these prints, documenting the process and results.
Reflective Report: A detailed analysis of a crime scene scenario where fingerprint evidence played a crucial role, including the methods used to lift and analyze the prints.
Guest Speaker Reflection: After the police officer's presentation, students write a brief reflection on how professional practices in fingerprint analysis align with what they've learned in class.
HS-PS1-3: Plan and conduct an investigation to gather evidence to support or refute an explanation or a model for a phenomena. This aligns with experimenting with different fingerprint lifting techniques.
HS-LS3-3: Apply concepts of statistics and probability to explain the distribution of traits in a population. Relates to analyzing patterns and minutiae in fingerprints as unique identifiers.
HS-ETS1-2: Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering. Applies to the development and application of fingerprint lifting techniques.
