The purpose of this exercise is to give introductory students experience in designing and carrying out an archaeology experiment. Such experiments are commonly used by archaeologists to generate modern analogues useful for studying past behavior. In this exercise, students design a research project aimed at studying the use of stone tools for butchering animals. The research projects look at the ability of archaeologists to discern differences in the material (flint, obsidian and steel) and edge treatment (serrated/unserrated, retouched/unretouched) of tools used to butcher animals. Student groups are given a description of the materials they will have at hand and work together to list the potential variables involved in the butchery of animals and . After designing a protocol for the experiment, the students use the different tools to make a set of carefully controlled cuts on fresh animal bones. These students (at right) are cutting deer bones taken from a local kill using an unhafted obsidian blade. |

The students are given background reading familiarizing them with the use of
a scanning electron microscope to describe the shape, depth and other aspects of cuts marks made by tools
on bones. Based on their background
reading, the student groups generate a set of predictions about if and how they expect to distinguish
between obsidian, flint, and steel tools
with various edge treatments.
During the observation periods, students work with the eSEM to examine depth, shape, clarity of the cut marks, as well looking for striations along the bones and other clues as to which cutting tool was used. The students prepare a report on their findings as part of their evaluated work for the course. ________________________________ Left: student groups using the eSEM with Dr. Lisa Park (Geology and Environmental Science) examine the cut marks in an interactive environment.

Above left: The tools used by the students include an unretouched obsidian flake (top left) and a retouched obsidian point (top right); an unretouched flint blade (middle left) and a retouched flint point (middle right); and an unserrated steel knife (third row) and a serrated steel knife (bottom row). The tools are used to cut into the bones using a predetermined number of strokes, force and blade angle. At the right, a student is making a series of parallel cuts on a deer bone.
Below are some of the photomicrographs showing the results of their experimental archaeology projects. Students were given access to the University of Akron Department of Geology and Enivornmental Science's environmental scanning electron microscope (eSEM) and acknowledge the generous help of Dr. Lisa Park and Dr. David E. Black with this part of the experiment.
