Sherlock Bones® Power Point Presentation Created by Anthony & Patricia Bertino Designed for use with Ward’s Kit 36-6082
At birth, you have approximately 450 bones which fuse at different times and rates to produce 206 adult bones
Background: The following bones were found in the woods Skull Femur Humerus Pelvis
Your assignment: Determine as much as you can about the remains that were found
Let’s reorganize the laboratory pages Remove staple from lab pages Re-staple pages 1-11 as a packet (directions) Re-staple pages 12-19 as a packet (data table) Re-staple pages 21-30 as a packet (reference pictures) Page 20 – list of all labeled bone regions ( leave separate for quick reference to labeled parts) Color coding of pages is also helpful
Another suggestion: Use the terms from page 20 to immediately label pages 22, 24, 29 and 30. You will save yourself time and confusion.
Measure Using a Vernier caliper Choose either the outside or inside scale Measurements will be to 1/10 of a mm Values are read with reference to the ‘zero’ mark. The zero mark represents the number of mm. Tenths of a mm. are read from the inside or outside scale where the sliding scale and permanent scale marks are aligned. See examples that follow.
Caliper Scales
Use the inside scale to determine the size of an opening.
Examples using the outside scale Femur head
16 mm+
No match Match! 22 mm+ 22.8 mm .8 read on upper scale
Outside measurement Lines match 7 mm+ 7.8mm
32.7 mm
45.6 mm Record the inside measurement
45.9 mm

Age of pelvis Age Determination Step 1 Age of pelvis can be determined by a study of cartilaginous line or epiphysis
Age determination from pelvis Epiphyseal union becomes less noticeable Approximate age? Age Determination Step 2
