Sherlock Bones Power Point Presentation Created by Anthony

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 22 mm+ Match! 22. 8 mm. 8 read on upper scale

Outside Lines match measurement 7 mm+ 7. 8 mm

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
