1. Sherlock Bones® Power Point Presentation
Created by
Anthony & Patricia Bertino
Designed for use with
Ward’s Kit

2. At birth, you have approximately 450 bones which fuse at different times and rates to produce 206 adult bones

3. Background: The following bones were found in the woods
Skull
Femur
Humerus
Pelvis

4. Your assignment: Determine as much as you can about the remains that were found

5. Let’s reorganize the laboratory pages
Remove staple from lab pages
Re-staple pages 1-11 as a packet (directions)
Re-staple pages as a packet (data table)
Re-staple pages 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

7. Another suggestion:
Use the terms from page 20 to immediately label pages 22, 24, 29 and 30. You will save yourself time and confusion.

8. 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.

9. Caliper Scales

10. Use the inside scale to determine the size of an opening.

11. Examples using the outside scale
Femur head

12. 16 mm+

13. No match
Match!
22 mm+
22.8 mm

Male: heart-shaped figure 3
Step 4

38. Age of pelvis
Age Determination Step 1
Age of pelvis can be determined by a study of cartilaginous line or epiphysis

39. Age determination from pelvis
Epiphyseal union becomes less noticeable
Approximate age?
Age Determination Step 2
