There are two parts to Lab #1. Part 1 reviews the scientific method with some thought experiments. Part 2 shows you how to measure and calculate an index of a shape and the indices of a skull and nose.
Part 1 “The Scientific Method” reviews the steps and concepts of the scientific method with “thought experiment” examples for you to do at home. The lab exercises are on the PDF file linked to this assignment below under “Supplies needed to complete this lab at home”. Your answers are typed on a PDF file or submitted as text to this assignment.
Part 2 “Measuring Skulls and Calculating Indices” is a review of the metric system of linear measurement that will are going to use in this class and it explains how to describe the shape of skulls using a number called an index. The lab exercises give you skull and nasal measurements and ask you to calculate a skull index called a “cephalic index” and a nose index called a “nasal index”. The lab exercises are on the PDF file linked to this assignment below under “Supplies needed to complete this lab at home”. Your answers are typed on a PDF file or submitted as text to this assignment.
Supplies needed to complete this lab at home:
Metric ruler with millimeters to complete Exercise 1.2 (page 13 “The Meaning of Indices”)*
*You will also need a ruler with metric millimeters on it to complete Lab 2. Below is a graphic of part of a metric ruler that is about a foot long with inches on one side and centimeters and millimeters on the other side of it. These are sold in stores like Target and Walmart and in most pharmacies and some grocery stores in the school supplies section.

Directions
Each lab assignment in this lab class will take an average of 1-2 hours to complete at home.
Lab #1, is the online version of Exercise 1 “The Scientific Method” in the Lab Manual for Anth 111 (7th Ed.) that is required for this class.
Lab #1 is one of the longest labs this semester. I recommend doing “Part 1” at a time, then “Part 2” another time, and then turning in your work all at once as copy-pasted text (or an uploaded single PDF file of only its exercise pages) after you finish both halves. For tips on converting your hard copies of the completed exercises into a single PDF file, scroll to the bottom of this webpage to “How to submit your completed paper exercise pages online.”
For example, you may want to complete this Canvas Assignment’s directions for the lab manual’s exercise Ex. 1.1 “The Scientific Method” for the first half and then read this Canvas Assignment’s directions for the other part and complete Ex. 1.2, 1.3, 1.4 and the Study Questions during the second half. And, then submit them together as one or two PDF files.

Ex. 1.2 “The Metric System” (pages 11-12 of the Lab Manual for Anth 111)
Read pages 11-13 in the Lab Manual for Anth 111 and then answer the following questions for Exercise 1.2:
Always measure in millimeters (not in centimeters and never in inches for these indices). 1. “Using a metric ruler, measure the height and width of Box A in millimeters.”
2. “Calculate the height divided by the width of Box A using the following formula: (height/width) x100 =
3. “Is this index a length?”
4. “What exactly does this index tell you about Box A (Hint: It’s shape! Okay that was the answer actually…).
5. Repeat the measurements and calculations for Box B:
Height = ___________
Width= ____________
(height/width) x100 = ______________
6. “How does Box B differ from Box A? Refer to the measurements and the indices in your answer.”
7. “Repeat the measurements and calculations for Box C”
Height = ___________
Width= ____________
(height/width) x100 = ______________
8 “How does Box C differ from Box A? Refer to the measurements and the indices in your answer.”
Important: You can round up your index numbers to two decimal places (but for this lab you do not have to). For example, 48 or 48.49 are both good answers for Lab #1.
–> For Exercise 1.4 and Exercise 1.5, you can use the cranial measurements that I am giving you on this Canvas Page (see below) to calculate the cephalic index and the nasal index.
Exercise 1.3 ” The Metric Analysis of the Human Body” (pages 12-13 of the Lab Manual for Anth 111) There are no questions or exercises. Just read this section.
Ex. 1.4 “Taking Anthropometric Measurements” (pages 13-14 of the Lab Manual for Anth 111)
Read these pages in the Lab Manual for Anth 111 and then answer the following questions on page 14 using the measurements of a skull I nicknamed “Fred” on this Canvas Assignment.
Important: You can round up your index numbers to two decimal places (but for this lab you do not have to). For example, 48 or 48.49 are both good answers for Lab #1. The specific numbers 48 or 48.49 may not be the correct answers for any of the questions in Lab #1. They are just examples.
Cephalic IndexNasal Index
Calculate the cephalic (cranial) index for this exercise with the following measurements for a skull I named “Freda”:Head width = euryon (eu) to euryon (eu) (p. 17) =122
Head length = glabella (g) to opisthocranion (op) (p. 18) = 165
Cephalic Index = (head width/head length) x 100 =
Ex. 1.5 “Measuring the Human Skull” (pages 14-15 of the Lab Manual for Anth 111)
–> Instead of measuring a skull in the Anthro Lab (which is impossible since this class is online), for this online lab use the cephalic and nasal measurements in millimeters for a skull I named “Freda” (see below)
Study Questions (page 16 in the Lab Manual for Anth 111)
–> Answer questions 1-12.
After you’re done, submit your answers via text or a photo (or scan) of your written answers on the bottom of page 20 of the Lab Manual for Anth 111 and upload to this Canvas Assignment. Below are some photos of the lab measuring tools mentioned. YOU DO NOT NEED ANY OF THESE TO COMPLETE THE LAB EXERCISES FOR THE ONLINE VERSION OF THIS CLASS. 🙂
Sliding Caliper: It is used to measure nasal index and other small items like seeds and bird beaks in millimeters. You do not need to use this tool for this online class.
Spreading Caliper: It is used to measure skulls, (to get the cephalic index) and other large round things like tree trunks*. For this online class, you do not need this.
* A “cephalic index” is the same thing as a “cranial index”.
Fred’s cephalic (cranial) index:

Fred’s nasal index:
Nasal width = alare (al) to alare (al) (p. 16) = 25
Nasal height = nasion (n) to nasospinale (n) (p. 17) = 45
