b. All the measurements you took can be used to determine height but it is clear that the raw data abone isn’t going to give you the height when you are looking at the measurement of only the upper les or arm. People approximation of height. However, the formulas are different for each bone and also for men and women. Use the formulas in Table 1-1 to determine the height predicted by your bone measurements. Fill your predicted heights into Table 1-2. Equations Used to predict Height From Bone Length TABLE 1-1 Male Female Femur length (FL) in cm Humerus length (HL) in cm (2.27 x FL)+ 67.985 (2.985 x HL) + 72.42 (2.375 x FL) + 57.13 (3.22 x HL) + 61.32 C. Compare arm span, the calculated height from femur length, and the calculated height from humerus length to the actual measured height of each person. Discuss the accuracy of each measurement as a predictor of height. Accuracy of arm span as a predictor of height Accuracy of femur (after calculation) as a predictor of height Accuracy of humerus (after calculation) as a predictor of height TABL 1-1 b. All the measurements you took can be used to determine height but it is clear that the raw data alone isn’t going to give you the height when you are looking at the measurement of only the upper leg or arm. People who work with bones and skeletons discovered that you can use bone length in a formula that gives an approximation of height. However, the formulas are different for each bone and also for men and women. Use the formulas in Table 1-1 to determine the height predicted by your bone measurements. Fill your predicted heights into Table 1-2. Equations Used to predict Height From Bone Length Male Female Femur length (FL) in cm (2.27 x FL)+ 67.985 (2.375 x FL) + 57.13 Humerus length (HL) in cm (2.985 x HL) + 72.42 (3.22 x HD) + 61.32 C. Compare arm span, the calculated height from femur length, and the calculated height from humerus length to the actual measured height of each person. Discuss the accuracy of each measurement as a predictor of height. Accuracy of arm span as a predictor of height Accuracy of femur (after calculation) as a predictor of height Accuracy of humerus (after calculation) as a predictor of height d. In any lab such as this, you are likely to make some crrors with the measurement or calculations. Discuss areas where your group, in particular, might have made errors in measuring, recording, or calculating. TABLE 1-2 e. In a few weeks, you will use these calculations again to determine height, but this time from actual bones. Data Table for Predicting Height From Bone Length Name of Height Temeke person being Humerus Wingspan Height (cm) Lenghth Com Lenght Height (cm) measured predicted by Tom (cm (cm) predicted by femur length Student humerus length Cerra 164 47 32 169 SKUU 2 Female 153 44 29 Suport 3 148 MOLT 168 45 30 156 sta mo 178 50 35 180 Part E: Bone Length Relationship to Height When human remains are found, scientists can use bones to tell them something about the dead person. For example, bones can be used to determine whether the person was male or female, an adult or child, and how tall the person was at the time of death. Height can be determined from the ratios between bone length and overall height, For this exercise you will work in groups of two to measure various bones to compare their length to overall height. 1. Get the required materials and bring them back to your group. 2. Locate Table 1-2 (page 10). You will record all your data in this table. You need to make sure you record the UNITS you are using. 3. The first measurement to take is height. a. Have one lab partner stand up against a wall and measure their height in centimeters. They should not have their shoes on. b. In Table 1-2 label the first blank column “Height (cm).” C. Fill in the height for the measured lab partner. d. Switch places and measure the other lab partner. Record this measurement in the proper place in Table 1-2. Collect this type of data from at least 3 other people and record it in the table. 4. The second measurement to take is for the length of the femur, the upper leg bone. Do this for each partner. a. The femur is the bone in the upper leg. To measure it, place the meter stick on the hip socket and measure to the top of the knee cap. b. Label the top of the second column of the table “Femur Length (cm).” C. Fill in the length of the femur for each partner. Collect this measurement from at least 3 other people and recor it in the table. 5. The third measurement is for the length of the humerus, the upper arm bone. a. Measure the length of the humerus by having your partner hold out their arm to the side. Then gently place the meter stick into their armpit and measure to the elbow. b. Label the top of the third column of the table “Humerus Length (cm).” C. Fill in the length of the humerus for each partner. Collect this type of data from at least 3 other people and record it in the table. 6. The next measurement is for arm span, the distance from fingertip to fingertip. a. Have one partner stand with their back to you. They need to hold both their arms out to the sides. b. Measure from one fingertip of one arm to the fingertip of the other arm. C. Label the top of the fourth column of the table “Arm span (cm).” d. Fill in the length of the arm span for each partner. Collect this type of data from at least 3 other people and record it in the table. 7. Evaluate the data a. Examine the data in your table. What correlations can you find (if any) between height and the other measurements?
