Campbellsville Elementary School students are learning about egg membranes in their science class.
In Doretha Sanders’s class, students recently performed an experiment to see just how tough the egg membrane is and how it protects an egg.
Students are learning about the parts of an egg, from the yolk to the embryo to the membrane, and the purpose of each.
To experiment, students first placed an egg in vinegar. Three days later, students observed how their egg had changed.
Then then removed their egg from the vinegar and the shell came off easily.
Next, students dropped their eggs at different distances to test how the membrane protects the egg.
Eventually, all the eggs cracked when dropped from a pretty high distance.
