While scientists place high value on the scientific method, its relevance to everyday life is often opaque to nonscientists. In undergraduate teaching, its implementation is primarily apportioned to upper-level, laboratory science classes for majors.

The transition from petroleum to biorenewable sources of carbon to meet our energy and chemical feedstock needs is difficult, in part because these sources are so different, with petroleum being under-functionalized and biomass being over-functionali
