Biogeochemistry science and education: part one, using non-traditional stable isotopes as environmental tracers : part two, identifying and measuring undergraduate misconceptions in biogeochemistry

This dissertation is presented in two sections. First, I explore two methods of using stable isotope analysis to trace environmental and biogeochemical processes. Second, I present two related studies investigating student understanding of the biogeochemical concepts that underlie part one. Fe and Hg are each biogeochemically important elements in their own way.
