Critical Thinking & Responsibility: Applying scientific knowledge and ethical considerations in the analysis of forensic evidence.
Learner’s Mindset: Embracing the challenge of mastering new skills, such as advanced microscopy, for real-world applications.
Communication: Effectively presenting and discussing scientific findings related to forensic hair analysis.
How do the unique structures and characteristics of hair, such as cuticle, cortex, and medulla patterns, aid forensic scientists in their investigations?
What forensic information can be derived from analyzing different types of hair found at a crime scene, and how can this information be pivotal in solving crimes?
How do forensic scientists utilize microscope skills to analyze hair samples, and what challenges do they face in interpreting these findings?
Students will accurately identify and describe the structural components of hair (cuticle, cortex, medulla) and discuss their relevance in forensic analysis.
Students will evaluate and interpret data obtained from hair samples, understanding its significance in the context of forensic investigation.
Students will apply advanced microscope techniques to analyze hair samples, demonstrating proficiency in recognizing different types of hair and their potential implications in a forensic context.
Assessment:
Practical Examination: Students will conduct a microscopic analysis of various hair samples, identifying structural features and presenting their findings.
Written Report: Students will prepare a report on a hypothetical crime scene, detailing how hair evidence was used to aid the investigation, including challenges encountered.
Class Presentation: Groups will present on the importance of hair analysis in solving crimes, highlighting case studies where hair evidence played a crucial role.
Activities:
Microscope Lab: Hands-on activity where students examine different hair samples under a microscope to identify cuticle, cortex, and medulla patterns.
Case Study Analysis: Students analyze real-life forensic cases where hair analysis was instrumental, discussing methods and outcomes.
Skill Workshop: A session focused on enhancing microscope techniques, including sample preparation and data interpretation.
HS-LS1-1: Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
