Skills and concepts that students must have mastered
How the activity is situated in the course
- magmatic processes in basaltic systems;
- hotspot volcanism; or
- using geochemical data in Earth systems.
Content/concepts goals for this activity
- integrating observations from multiple resources on active hotspot volcanism in Hawaii (e.g. maps, photographs, satellite imagery, video footage, background reading, monitoring data);
- observing hand samples and thin-sections of recently erupted lavas;
- making and interpreting geochemical plots of lavas from eruptions on Kīlauea Volcano as part of a time-series analysis;
- formulating and evaluating hypotheses on crustal magmatic processes; and
- synthesizing, presenting and discussing information about petrologic processes associated with active volcanism at Kīlauea Volcano.
Higher order thinking skills goals for this activity
Other skills goals for this activity
1. integrating observations from diverse sources of background information presented on the World Wide Web;
2. working with geochemical data to critically evaluate hypotheses of magmatic processes;
3. collaborating on a particular phase of the eruption in preparation for group oral presentation and discussion.
Description of the activity/assignment
- Pre-lab material provides background on the Hawaiian hotspot and the current eruption utilizing maps, diagrams, information, photographs, and video footage of the Pu'u 'Ō'ō-Kupaianaha eruption with written questions that test understanding of this material.
- Examination of hand samples and thin-sections of lavas from a distinct interval of the Pu'u 'Ō'ō-Kupaianaha eruption with group partners in lab.
- Working within groups assigned to particular intervals of the eruption to make time-series analyses of whole-rock geochemistry from the Pu'u 'Ō'ō-Kupaianaha eruption to evaluate crustal processes of magmatic evolution.
- Interpretation and synthesis of background information, petrography, and geochemistry, and presentation of results and interpretation with group partners at the beginning of the next lab period.
