Exploring Volcanoes: Hands-on Petrology Lab

This lab provides a cooperative, problem-based learning experience for students to gain a deep understanding of volcanic processes through hands-on activities in volcanology, geochemistry, and petrology.

Presentation Transcript

  1. Andrew Greene and Michael Garcia Univ. of Hawai‘i at Manoa Tim Orr USGS Hawaiian Volcano Observatory SERC Carleton: Teaching Petrology in the 21st Century http://serc.carleton.edu/NAGTWorkshops/petrology/teaching_examples/35081.html

  2. Goals: 1) Share excitement of eruption! 2) Cooperative, problem-based learning 3) Gain understanding of dynamic nature of volcanoes and magmatic processes 4) Hands-on experience with volcanology, geochemistry, and petrology February, 2009

  3. What students do : • Pre-lab material provides background utilizing maps, diagrams, photographs, video footage and information of the • Pu‘u ‘Ō‘ō eruption with accompanying questions. • 2. Examination of hand samples and thin-sections of the Pu‘u ‘Ō‘ō eruption lavas with group partners. • 3. Time-series analysis of whole-rock geochemistry from the Pu‘u ‘Ō‘ō eruption to evaluate crustal processes of magmatic evolution. • 4. Interpretation and synthesis of background information, petrography, and geochemistry, and presentation of results at the beginning of the next lab period. Pre-lab In-lab Post-lab Prerequisites: -experience with Excel -one class on hotspot volcanism (helpful)

  4. Lab components Pre-lab material Video footage Provided by Volcano Video Productions Pre-lab reading Slide show Background information via html Google Earth files (photos and maps)

  5. Lab components In-lab material Hand samples (rock sample from group interval) *can request samples from Michael Garcia In-lab exercise Thin-sections (of group sample- or may use online photomicrographs) Working in groups Geochemistry (make plots and interpretation) (compare volcanology, geochemistry, petrology to other intervals)

  6. Insights into magmatic processes in the East Rift Zone Fractional crystallization and magma mixing

  7. Assessment How can we tell if the lab makes an impact in the class and achieves our goals? -evaluate presentations of each group (provide assessment criteria prior to presentations?) -questions generated by students -post-lab questions and feedback (self-evaluation) -were tasks accomplish by collaboration no vuvuzelas allowed Discussion and ideas for assessment: http://serc.carleton.edu/introgeo/assessment/index.html
