Forensics

This activity explores how forensic science utilizes physical characteristics and skeletal examination to identify individuals. We look at aspects like skin color, eye color, hair color, height, and body type. Discover how to identify a body through measurement of major bones like the femur and tibia to estimate height, as well as determining shoe size without measuring the foot directly. Engage in hands-on measurement exercises to apply forensic principles and understand their significance in identifying individuals.

Presentation Transcript

  1. Forensics Activity 2

  2. What can we tell by examining a person? • Skin color? • Eye Color? • Hair Color? • Boy or Girl? • Tall or Short? • Heavy or Thin? • Big or Small?

  3. What about trying to identify a body? • We can learn a great deal from examining the skeleton. • But first we need to know the major bones. • Do you know them?

  4. The Human Skeleton

  5. Now you try!!!

  6. What about trying to identify a body? • We can determine the height from measuring the bones. • Measure the Femur bone and the Tibia bone of the leg in centimeters. • Multiply by 1.30, then add 63 cm • Use this formula: Height =1.30 x (length of femur + length of tibia) + 63 cm

  7. Measurement Number 1 Measurement Number 2

  8. What about trying to identify a body? • We can determine the shoe size without measuring the foot. • Use this formula: • Measure the distance between the bend of the elbow and the wrist.

  9. Measure from bend of the elbow to bend of the wrist

  10. With a partner, measure your femur and your tibia, using a tape measure. Using the formula we learned earlier. Did you get your height correctly? With a partner, measure the distance from the bend of your elbow to your wrist. Now measure your foot. Is it the same? Now try these on yourself!
