Due this week: October 1st to October 5th
- Monday: Career Journal due today Forensic Anthropologist in PLTW journal Activity: BONE DETECTIVES 1.2.3
- Visit the website Visible Proofs: Forensic Views of the Body by the National Library of Medicine.
- Visible Proofs: Forensic Views of the Body / National Library of Medicine
- In the section “Learning from Bones”, complete the visual comparison activities to determine the sex and ethnic origin of the skulls.
PLTW LABORATORY JOURNAL Take notes on the bone landmarks you used in your analysis. - To learn more about the field of forensic anthropology and the duties of a forensic anthropologist, read the two interviews found at the bottom of the Visible Proofs webpage (Barbian and Sledzick).
- Use the ideas presented in these two discussions to come up with your own definition of forensic anthropology. Write this definition in your career journal.
- Tuesday:
- Obtain a Results and Analysis Data Sheet from your teacher. On the top of your data sheet, write whether you have skeleton "A" or skeleton "B".
- Divide your team into four groups. Each group will begin at one of the four bone stations.
- Bring your Maniken® with you to each station.
- Rotate through the four bone identification stations for your skeleton and complete your analysis. At each station, you will gather both qualitative and quantitative data. Determine which bone you are analyzing and locate the appropriate data tables on your Data Sheet.
At each bone station, complete the following steps. Along the way you will encounter many terms for bones or for markings on bones that you may not have heard before. Use the laminated photographs and your knowledge of directional terms to help decipher these clues and complete each step of the analysis. - Use the instruction card, photographs, and tools at each station to complete the observations or measurements listed for that bone. Determine as much as you can about the person’s sex, race, and age.
Work with your group to come to consensus on each trait/measurement. Record your findings on the Data Sheet.
For the following structures, mark the bone or bone landmark on your Maniken with a pencil. Use the skeletal remains and the laminated photographs to find and identify each structure. Continue the key you began in Activity 1.2.1 and 1.2.2 to link features on your Maniken to your skeletal system graphic organizer - Ischium
- Illium
- Coccyx
- Sacrum
- Pubis
- Pubic Symphysis
- Eye Orbit
- Nasal Cavity
- Zygomatic Bone
- Mandible
- Maxilla
- Femur
- Tibia
- Humerus
- If you are waiting to view your next bone, take the measurements of the enlarged skull photos to determine the nasal index for the three ethnic groups. The procedure is outlined in the instruction card found at the skull and additional copies of this protocol should be available from your teacher. This information will be a useful comparison when determining ancestry from the skull.

- When your group has made preliminary findings regarding the sex and ethnicity of the remains, use the equations listed in the data tables to estimate height.
- To determine the probable height range of the individual, refer to the height tables and record the minimum and maximum value of the calculated height ranges (looking at both bones). Convert the minimum and maximum value to feet and inches and estimate the height range of this individual.
- Meet with your entire team to discuss results and come to consensus on the characteristics of your assigned skeleton. If groups disagree, you may need to go back to specific bones. Work together to form a conclusion about sex, height, ethnicity, and age.
- Wednesday
- Thursday
- Friday PLTW LABORATORY JOURNAL Reflection Question: Explain how both quantitative and qualitative data played a role in your analysis.
- To analyze the long bones, the femur, and the humerus, you looked at bone markings, such as condyles, tuberosities, and trochanters. Look back at the photographs and the bone markings on your Maniken and answer the following.
- How would you describe these markings in your own words?
- Which features do you think separate each class of markings from the others?
