Chicken Skin

Class: BE 210
The purpose of this lab is to compare the mechanical properties of
chicken skin under two heating conditions: 25ēC to simulate an unburned sample
at room temperature and 85ēC to simulate a burned sample. Since burning an
object changes the inherent properties of the material under investigation, it
is hypothesized that the material properties will be statistically different
for the two conditions of the skin sample. In particular, the aim of the lab is
to focus on one of the material properties, based on past in-class experiments;
thus it is hypothesized that the elastic modulus of chicken skin will be
statistically significantly different under the two conditions. Moreover, the
elastic modulus of the samples at 25ēC will be higher than the elastic modulus
of the samples at 85ēC. The samples will be split into two groups; The first
group of chicken skin samples will be placed in an oven at 25ēC (room
temperature) for thirty minutes, the second group will be placed in an oven at
85ēC for thirty minutes. To test the
data, a paired two-tailed t-test at the 95% confidence interval will be
performed to determine support or rejection of the null hypothesis.
