While moleskin refers to the skin of an animal called a mole, that is not the most common meaning for the term. The most common is a heavy napped cotton twill fabric that is extremely soft. The fabric is woven and then sheared to cause a soft, short pile on one side of the fabric.
One thing that stood out to me is that freshmen are given the option to take AP Human Geography, as opposed to Civics and Geography, which has been the only option in the past for the required 9th grade social studies credit.
From College Board. The purpose of the AP course in Human Geography is to introduce students to the systematic study of patterns and processes that have shaped human understanding, use, and alteration of Earth's surface. Students employ spatial concepts and landscape analysis to examine human social organization and its environmental consequences.
