Answers to Questions
There is a straight line relationship.
Student answers will vary.
Ulna length __________ cm
Ray Torres would seem to be the best candidate from the three possible missing persons based upon the earlier prediction graph. Since all individuals were adults at the time they were reported missing, the comparison seems justified.
A dead body has been found and the only things remaining are the bones! What can be learned about the dead person?
There are more than 200 bones in the human body. For the average male these bones weigh 12 pounds; the average female, 10 pounds. Study of bones can reveal a great deal about a person (dead or alive). Bones may reveal how people lived, how well they ate, whether they had certain diseases, whether they had fractures, whether they were left- or right-handed and maybe even give clues about their occupation. When skeletal remains are found, several important questions must be answered—and often the answers can be determined from just studying the bones:
The female pelvic cavity is wider in all diameters and is shorter, roomier, and less funnel-shaped than the male pelvis. The female pelvic bones are lighter, thinner and have less obvious muscular attachments.
In this activity, the height of a person will be predicted using the length of their ulna bone. The ulna bone is the long bone running from the elbow to the wrist on the outside of the arm (see Figure 3).
Male [3.70 x ulna length (cm)] + 74 cm = height (cm)
