Description of the activity/assignment

Students examine a geologic map of Hawaii and begin to decipher it. In particular, students are asked to examine the map and its legend, to answer some specific questions about them, and then to answer the overarching question, "What evidence is there on this map that the Hawaiian Islands formed over an oceanic hotspot?"

Determining whether students have met the goals

Working alone or in groups, students write a report summarizing (a) how the Hawaiian Island – Emperor Seamount chain has formed; (b) how mafic magma forms gabbro, basalt, vesicular basalt, or obsidian, depending on its cooling history; and (c) the evidence on the geologic map of Hawaii that these islands formed over a hotspot. I evaluate their report using a rubric, included in the lab handout.
