1) the properties of materials under deep Earth pressures and temperatures;

2) the technologies, equipment, and facilities needed to study materials under deep Earth conditions; and

3) what materials properties research has revealed about deep Earth processes.

Regarding technologies, I worked with a group of students to develop an interactive applet that demonstrates Bragg's Law. See http://www.eserc.stonybrook.edu/ProjectJava/Bragg/

During this workshop, I am considering developing some educational activities that utilize this applet, but am primarily interested in helping other workshop participants with their projects.

I am happy to see that other members of the COMPRES community are enrolled in this workshop. Perhaps some of them can help stimulate ideas for additional educational resources by posting their thoughts to this thread prior to the start of the workshop. ]]> Glenn Richard 1265906820 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post5879 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6284 http://www.iris.edu/hq/resource/determining_internal_structure) and i'd like to know if anyone has anything similar written at the college level.

I'm also looking for activities which help explain the process of seismic tomography.

IRIS has a large online archive of seismic data, along with several access tools and we are interested in working with anyone who wants to help develop activities using that data, as we would like to expand our resources for the college audience.]]> John Taber 1266334800 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6284 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6484
"In geophysics I used to have my students figure out what the earth would need to be composed of if it were hollow (using a shell thickness suggested by hollow earthers) given the radius determined by Eratosthenes and mass determined by Maskelyne. I always found that amusing but my students tended to founder on the math."

Pam, are you aware of any existing online resources that could be effective for helping students understand the math? If not, can you think any new resource that could be developed to facilitate this understanding?]]> Glenn Richard 1266410100 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6484 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6486
"In terms of teaching, I am looking for more hands-on activities for my students, perhaps even some that takes them out into the field. My "field" is the laboratory which can come across less-exciting, especially for someone taking a geology course. Currently I do a corn syrup demo and try to measure gravity changes with a gravimeter. We've also set up some geophones and hammered away to show some reflection seismology. I could use more ideas."

Kanani, do you have any support materials for your lab tours, or descriptions of the corn syrup or geophone activities that you would like to share with us?]]> Glenn Richard 1266411180 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6486 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6606
I also wonder about trying to get Wards or some other vendor to put together education teaching suites that might include a small polished bit of Fe meteorite, a sample of perovskite (not sure how easy this is to obtain), garnet peridotite and spl peridotite for a reasonable price [Dave I know some suites were developed and sent out for Teaching Petrology - don't know if there would be a way to do this for lesser cost through SERC???]]]> Ben Edwards 1266457080 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6606 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6674
It might be interesting for someone to put together a collection of Deep Earth samples: lower crust and mantle xenoliths, as Ben suggests some analogues for even deeper earth (perovskite, Fe-meteorite) etc. We could at least help post this info as a virtual collection--post photos of rocks, photomicrographs, geochemical data sets, physical property data....Not quite sure how to distribute real samples but I'm open to suggestions.

BTW, folks might be interested in looking at Barb Dutrow's article in Journal of Geoscience Education, Teaching mineralogy from the core to the crust v.52 p. 81-86 ]]> Dave Mogk 1266471600 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6674 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6799
1. Phase transitions: At the CIDER workshop this coming summer in Santa Barbara (http://www.deep-earth.org/) one of the mineral physics lecturers is planning an interactive tutorial activity on phase transitions in the deep Earth. Not sure yet what this will look like but I will keep my eyes open.

2. Deep Earth samples: I have a collection of hand samples I use for showing deep Earth materials: a chondrite meteorite, and iron meteorite, mantle peridotite (San Carlos), ocean basalt, and a nice granite. I use them for show and tell, and to demonstrate density.]]> Abby Kavner 1266548100 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6799 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6816 Anna Courtier 1266579720 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6816 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6821
Part of the reason for mentioning this is that we always get a tour of the meteorite collection (the students got to hold a likely piece of Mars last fall), and I know that they have thousands of samples, many of which are available for research 'loans'. I wonder if they might be open to making long-term 'loans' of small pieces of meteorites for teaching?? Having a polished piece of iron meteorite showing W-S textures is very nice for visualizing the inner core, and a piece of pallasite gives an approximate idea of what D'' might be like. I know their collection is mainly for research, but they have so many samples it would seem reasonable to get some long term loans.

Two other possibilities to facilitate this might be to try and form regional groups, which might be able to coordinate and share a Smithsonian 'loan' collection, or trying to see if NSF/SI would be willing to fund some annual 'rock tours' for SI petrologists/mineralogists to bring to the Smithsonian samples to groups of students, coordinated with classes. This would be maybe more attractive if local college/uni hosts could organize visits to local K-12 schools as well...so the SI would get a big return for the travel investment.

I know some places in BC where I could easily collect hundreds of spl peridotite xenoliths, and have seen some retrograde ecologites in North Carolina. The 'best' eclogites I've seen are of course from Norway, but most of the garnet peridotites I've ever seen are from kimberlites, and it's not very easy to get samples...not sure I know any Norwegian petrologists that could coordinate a large-scale rock swap...do any of you??]]> Ben Edwards 1266590820 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6821 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6822 Ben Edwards 1266591000 http://serc.carleton.edu/NAGTWorkshops/deepearth10/discussions/new_teaching_ac.html#post6822
