- The UT Austin outreach was conducted Thursday June 23, 2011 and Tuesday July 5, 2011 in collaboration with Mary Miller and her intern Sara Jeanes of the UTeach program at the University of Texas- Austin. The UTeach program focuses on preparing undergraduates at UT-Austin to teach secondary science courses such as chemistry, biology, geology, and computer science. UTeach hosts a three-week summer camp every year to expose students to these subject areas, as well as to keep them engaged during the off-season. The students that came to the mineral physics lab were participants in math, chemistry, or geology focused camps. Many students were underrepresented minorities, and some required translation. The students ranged from 6th to 7th grade and were from various schools in Austin including the Kealing Magnet Program. All students underwent a pre-lesson before coming to UT, subjects were pressure, crystal structure, or diamonds. The theme of the mineral physics lab tour was, “diamond anvil cell and high-pressure research” One group of 19 students, six groups of 12 students, and one group of about 10 teachers, each explored the lab, passed around a diamond anvil cell (DAC), observed real and synthetic diamonds, witnessed ruby fluorescence, and learned about the relationship between pressure and area and how it is exploited via the DAC. The students learned how Raman spectroscopy and the DAC can be used to study properties of planetary materials at extreme conditions in the Earth’s deep interior as well as projects related to Energy Frontier Research under Extreme Environments (EFree) of the Department of Energy. We learned about how extreme environments can change material properties and how novel materials can be discovered under extreme environments in a DAC. Jung-Fu Lin appointed Andrea Wheat, an undergraduate researcher, to help out with the presentations in the lab. [photo: Andrea show the students a schematic of a diamond anvil cell and sample area.] Lastly, the teachers and students were shown 200 diamonds and given broken diamonds as rewards for asking good questions or for answering questions.
