Making Solid Solutions with Alkali Halides (and Breaking Them) part of Mineralogy:Activities
In this exercise, the class will grow a variety of crystals of the same mineral, but with different chemical compositions. These crystals will be made from mixtures of halite eNaCI)and sylvite (KCI) that are melted ...
Enthalpy of Magmatic Crystallization part of Petrology:Teaching Examples
This is a problem set that gets students to think quantitatively about magmas. To be most effective, it should be done in conjunction with a showing of some or all (I recommend some...) of the movie ...
Phase Diagrams from Kitchen Chemistry part of Petrology:Teaching Examples
The main pdf file describes a series of lab or lecture activities using water, salt, ice, sugar, and alcohol that can be used to help students understand simple phase diagrams. The supporting pdf file contains ...
Graphing Chemical Data to Identify Fractional Crystallization part of Petrology:Teaching Examples
Students are given major-element, whole-rock chemical analyses from ten samples of lava from the 1868 eruption of Mauna Loa. They do not know sequence of eruption, only that the lavas came from the same volcano. ...
Conference Presentation (1)
Mineral Identification using FTIR Spectroscopy part of Earth Educators Rendezvous:Previous Rendezvous:Rendezvous 2016:Program:Teaching Demonstrations:Tuesday A
Opportunity to introduce FTIR and Raman spectroscopy into the undergraduate Geoscience curriculum at all levels at modest cost. We have acquired and used these instruments in introductory and intermediate courses ...

Useful Phase Diagrams part of Petrology:Teaching Examples
These are some drafted phase diagrams that may be useful as part of pdf slide shows to illustrate lectures or as handouts. Some are schematic; some are based on experiments. PDF files can be opened with Adobe ...
Plotting Mineral Compositions, and Chemographic Projections part of Integrating Research and Education:Teaching Phase Equilibria
John Brady (Smith College) and Cam Davidson (Carleton College) Minerals and rocks have chemical compositions that comprise some of the most important data for phase equilibria studies. Important relationships ...
Phase Diagrams (and Pseudosections) for Petrologists part of Integrating Research and Education:Teaching Phase Equilibria
Compiled by Dexter Perkins (University of North Dakota) and John Brady (Smith College) Standard phase diagrams are graphical representations of the equilibrium relationships between minerals (or others phases). ...
Mineral Formulae Recalculation part of Integrating Research and Education:Teaching Phase Equilibria
John Brady, Smith College and Dexter Perkins, University of North Dakota What is it? Chemical analyses for silicate minerals are commonly reported in weight percentages of the oxides of the elements determined. ...
Igneous Rock Classification part of Starting Point-Teaching Entry Level Geoscience:First Day of Class:Activities
John Brady, Smith College Course: Petrology 10 students The most effective way to develop geoscience skills in your students is to make opportunities for them to practice those skills. Although prior knowledge may ...
