MYSTERY OF THE BONES Anatomy Week 18

MYSTERY OF THE BONES!  The Scene  In a quiet camping area known as Crystal Lake, four complete human skeletons were found in the mud when the lake began to dry during a drought. Detectives checked the missing person's reports for people in the area and found that five people had disappeared from that area over the last 10 years.  Oddly, the skeletons were almost completely intact due to being somewhat preserved in the clay at the bottom of the lake.

PHOTOS OF THE REMAINS

INSTRUCTIONS  1. Each group should pick a bone set and reconstruct the skeleton using glue, scissors and tape.  2. Each bone of the skeleton should be labeled  3. Next your small groups will need to determine the identity of the bones based on age and height  a. Determine the gender of your subject by looking at the shapes of specific bones  b. Use the following formula to determine the height of your subject  Your paper skeleton is not a real skeleton. Assume that 1cm on your paper skeleton = 8.6 cm on the real skeleton Male (real) (2.32 x length of the femur in cm.) ± 3.94 Female (real) (2.47 x length of the femur in cm.) ± 3.72  4. In your notebook, include information about the gender and height of the skeleton and describe your reasoning for your claims (include formulas or arrows to bones, etc)

 Each of the skulls from the subjects were examined in detail. See if you can determine their age (either over 35 or under 35) by the sagittal sutures.  Remember that sutures close fully by the age of 35.  On your skeleton reconstruction page, note whether the skull indicates the person is over 35, or under 35. DETERMINING AGE

THE MISSING PERSONS  Name: Sara Munchausen  Age: 21  Height: 5'0  Weight: 105 lbs

THE MISSING PERSONS  Name: Jamie Matthews  Age: 18  Height: 6'2  Weight: 190 lbs

THE MISSING PERSONS  Name: Neil Baxter  Age: 22  Height: 6'1  Weight: 210 lbs

THE MISSING PERSONS  Name: Robert Downey  Age: 45  Height: 5'7  Weight: 190 lbs

THE MISSING PERSONS  Name: Eva Longori  Age: 55  Height: 5'8  Weight: 140 lbs

 As a group, make a prediction about which of the four skeletons might belong to our missing persons and describe the evidence to back up your prediction. PREDICTION

FACIAL RECONSTRUCTION

 Write a one to two page paper describing the scientific process of your investigation The problem Background information/Context The data Your prediction based on your data And the results and analysis of your prediction after seeing the facial reconstructions. Also include a reflection on the process about how you could have improved your investigation; organization, measurement accuracy, mathematical manipulation, YOUR SUMMATIVE
