The primary objective of this experiment is to evaluate the mechanical properties of plaster of Paris, a common bone repair material, as compared to chicken bones. We hypothesize that plaster of Paris has higher fracture energy, as it is denser than chicken bones.

The secondary objective of this experiment is to explore the fracture properties of broken bones repaired with plaster of Paris. We hypothesize that the repaired chicken bones will re-fracture at the original point of fracture, and that the yield strength and stiffness of the repaired chicken bones will be significantly lower than normal chicken bones.
