Kami Export - Lab Activity-1 Forensic Anthroplogy Height copy

Lab Materials: • Metric Ruler, Tape Measure • Calculator No Bones About It (Part 1) When a body is discovered, it is important to learn as much as possible from the remains. Forensic anthropologists use mathematical formulas to estimate someone’s height from the lengths of certain bones in their body. But where do these formulas come from? 1. Using a metric ruler, measure the length of your femur (thigh bone) in centimeters. This is the large bone that runs from your hip socket to your knee cap. Record this information in the table below. 2. Have a partner measure your actual height in centimeters. Record this information in the table below. 3. Collect the same information (femur length and height) from at least 7 of your classmates. Leave the “calculated height” row blank for now. Table 1: Classroom Measurements Name Femur Length (cm) Actual Height (cm) Calculated Height (cm) 4. Use the graph paper on the next page OR GOOGLE SHEETS to graph the data you’ve collected. Use Femur Length for the x-axis and Height for y-axis. 167.

No Bones About It (Part 3) The following bones were recovered from the construction site. Unfortunately, the bones were heavily damaged by the construction equipment. The bones have all been mixed up and several have been crushed. However, you think you can use the bones that are left to: • Determine how many people were buried at this location • Determine the heights of the different individuals A fellow forensic anthropologist has already classified the bones by sex and race. Using the mathematical formulas from Table 2 , calculate the approximate height of each individual. Table 3: Analysis of bones from construction site Bone# Type of Bone Length (cm) Race Sex Calculated Height (cm) 1. Humerus 38.2 Caucasian Male 2. Femur 44.0 African- American Female 3. Ulna 25.4 Caucasian Male 4. Femur 52.4 Caucasian Male 5. Femur 43.9 African- American Female 6. Tibia 43.7 Caucasian Male Questions: 1. Is it possible any of these bones came from the same person? Which bones? 2. What is the minimum number of bodies buried at this site? What is the maximum number of bodies? 3. Do all bones from the same body give exactly the same height? If not, why would the heights be different?

Final Analysis: 1. Using the database and Table 3 , determine the possible identities of the people buried at the site? 2. Are the heights exactly what you expected them to be? Why or why not? 3. What are some possible sources of error in your identification? 4. What other forensic tests could you do to test your deductions?

Part 6 – Current Events - Mass Grave 1. Read the following article - https://www.nytimes.com/2022/09/16/world/europe/ukraine-graves- russia.html 2. List at least 4 facts learned from the article . 3. A shallow grave, filled with the skeletal remains of what is believed to be at least two people, was recently discovered in a nearby county. Only a mix of arm and leg bones were found in the grave, which has made it difficult for the sheriff’s department to determine exactly how many victims were buried. The sheriff’s department carefully measured each bone’s length (bone length is the only information they have been able to gather from the skeletal remains). This bone length data just arrived in our lab today. They would like for you to use height calculations to help determine the number of victims in the grave. Formulas used to calculate Estimated Height when Race and Sex are Unknown Humerus Unknown (4.62 x length) + 19.00 cm Radius Unknown (3.78 x length) + 74.7 cm Ulna Unknown (4.61 x length) + 46.83 cm Femur Unknown (2.71 x length) + 45.86 cm Tibia Unknown (3.29 x length) + 47.34 cm Fibula Unknown (3.59 x length) + 36. 31 cm Six months of Russian occupation of the city of Izium left an estimated 400 people in a large burial site. Bodies are being exhumed to try and determine causes of death. It can be determined that many of the dead are women and children. Some of those killed may constitute war crimes on the part of the Russions.
