This case study documents what happened in Jenny Tamper's 10th-grade biology class when she showed her students a stanza from Samuel Taylor Coleridge's poem "The Rime of the Ancient Mariner," and asked them to explain what they thought it was describing. The high school biology curriculum guide used in Jenny's district suggests this activity. It is intended to give students an opportunity to apply their understanding of osmosis and associated vocabulary to their interpretation of the poem. Before beginning the case study, the chapter offers suggestions for reading and viewing.
