Anthropology 176 Forensic Anthropology Lab 2 Anatomical Terminology and the Human Cranium Station 1. Starting this week, we will be handling bone materials for the remainder of the term. Before doing so, we want to make sure you have read the guidelines and ethics in our Forensics Anthropology course, and consider your responsibilities in handling remains and casts. Please read the information below, and then sign and date to indicate that you have read and understand the guidelines and your responsibility. Handle the bones/casts with respect. Understand that you are handling real remains or casts that come from real remains, and that these are real people. You should handle all remains with care and respect. This includes carefully holding any remains (including casts) if you decide to pick them up, using two hands where necessary, carefully placing all remains back on a foam mat, not using a pencil/pen to mark on remains or damage remains, letting your GE know immediately if remains have been damaged, and not eating or drinking in the lab. If you learn that some way you handled or treated remains was disrespectful or careless, listen carefully to the GE and be sure to prevent that behavior in future labs. Listen respectfully. Arrive to your lab on time. Don’t interrupt, turn to technology, or engage in private conversations while your GE is speaking. Lab time is minimal, and they are providing you with essential information. Be attentive and courteous to your GE and to your fellow peers when in lab. Take pair work / small group work seriously. Working in pairs/groups is an ideal way to learn the bones, features, and how to analyze those bones/features in biological profile analyses. Be willing to engage with your fellow peers, and to help answer their questions. Remember that your peers’ learning is partly dependent upon your engagement. You are an essential part of this course now. Keep in mind that this is a forensic lab dealing with human remains and casts. Use technical and professional language. Be respectful to the bones and to each other. Being able to communicate and collaborate effectively are critical skills that are essential for a practicing forensic anthropologist. Try to get to know other students . Introduce yourself to fellow peers in the class, be willing to work with each other and to help each other complete the worksheets. You might also exchange contact information, and meet and study with each other outside of class. Strive for a perfect worksheet in the lab . Be willing to ask your GE if you are uncertain of a bone or feature. Stay in the lab and make sure the worksheet is completed before leaving the lab. Before leaving, you should be 100% confident that your answers are correct. If you are unsure, you should ask your GE or your peers, and then review the material so that you continue to develop a familiarity with the bones/features/analyses. If you have completed the worksheet before the lab is over, consider reviewing other bones/features, or helping peers to grasp the material. Signature indicating that you have read the above guidelines/responsibilities for Anth 176 labs, and understand your role and responsibilities (you can type in your name) Name: Kai Yarbrough Date: 10/6/23
