# Webquest: Mystery of the Bones (Part II)

## 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.

Instructions

1. Each team member 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 you 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.) +65.53 ± 3.94 Female (real) (2.47 x length of the femur in cm.) + 54.10 ± 3.72

Feet to Cm height conversion

4. On your reconstructed skeleton, include information about the gender and height of the skeleton and point out your reasoning for your claims (include formulas or arrows to bones, etc)
