  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!
