Crossword Puzzles to Review Mineral Concepts part of Mineralogy:Activities
Laura Wetzel, Eckerd College
Students complete a crossword puzzle to review the physical properties of minerals that are helpful in hand specimen identification. Mineral names and characteristics are particularly well-suited for a crossword format. Two versions are provided, one at an introductory level and one for more advanced undergraduates. Instructor files provided are easy to customize.

Mineral Recalculation Using Remote Electron Microprobe Analysis part of Mineralogy:Activities
Sven Holbik and Rosemary Hickey-Vargas, Florida International University
This in-class activity uses the remote capabilities of the electron microprobe (EM) system with wavelength dispersive spectrometry (WDS) available through the Center for Analytical Electron Microscopy (FCAEM; fcaem.fiu.edu) at Florida International University in Miami FL, to introduce students to microprobe analysis, determine the major chemical elements in a mineral, use the chemical data to calculate the exact chemical formula of the mineral and to plot this data on a binary phase diagram for interpretive discussions. This instructor led activity is intended as a whole-class demonstration of the EM with WDS analysis of minerals. The remote user will navigate the EM stage to find phases of interest, acquire images of phases, set up multiple points for analysis, and disseminate collected data for students to answer questions given in lab assignment.

Feldspar Mineral Chemistry Using the FCAEM Remotely Operable Electron Probe Micro-Analyzer. part of Mineralogy:Activities
Sven Holbik and Rosemary Hickey-Vargas, Florida International University
This lab uses the remote operation of an Electron Probe Micro-Analysis (EPMA) available through the Florida Center for Analytical Electron Microscopy (FCAEM; https://fcaem.fiu.edu/), at Florida International University, Miami, to explore feldspar mineral chemistry. This lab explores detailed mineral chemistry, data normalization, and plotting compositional ranges on ternary diagrams suitable as an introductory assignment in a Mineralogy, Earth Materials, or Petrology course. This instructor-led interactive demonstration of remote Electron Microprobe use introduces students to microprobe analysis, x-ray analytical techniques, standardization, image analysis, normalization, mineral formulas and composition. The instructor can acquire images (optional) of samples containing feldspar (provided by FCAEM or instructor's samples) then select multiple points for analysis. This activity captivates student's attention and provides a hands-on instrument-led approach to introducing undergraduate students to chemical analysis and vital concepts in mineralogy and petrology.

The Nature of Science and Scientific Fraud part of GeoEthics:Activities
Dexter Perkins, University of North Dakota-Main Campus
Dexter Perkins, University of North Dakota Summary There are two parts to this exercise but they are stand-alone if desired. The first part deals with the nature of science: what is science, what does it involve, ...

Introduction to Mineral Identification part of Geoscience in Two-year Colleges:Activities
Suki Smaglik, Laramie County Community College
The exercise uses an inquiry-based approached to overcome the fear of tackling mineral identification. Few instructions are given and students discover for themselves how to approach identification.

Observational Skills in a Simple Crystal Growing Experiment part of Geoscience in Two-year Colleges:Activities
Richard Gottfried, Frederick Community College
Students grow crystals and identify the crystal system by observing their basic geometric form. Students all research crytallization processes.

Mineral Selfie part of Introductory Courses:Activities
Stefany Sit, University of Illinois at Chicago
Students identify minerals used in their everyday lives by taking a 'selfie' with the product and then sharing their photo with their fellow students on a class blog.

Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a Web investigation and research exercise starting with the 2003-present Anatahan volcanic eruptions in the Mariana arc, and concluding with a petrologic examination of published Mariana arc lavas data sets.

Mineral Properties -- Learning through Experience part of Geoscience in Two-year Colleges:Activities
Katryn Wiese, City College of San Francisco
Students are each given a mineral and asked to locate all other students in the room with the same mineral (knowing there are a total of 5 different minerals). Once groups form, they need to decide what characteristics are similar for all their samples and ultimately report out to the whole class on their observations.

The Silicate Structures: Chalkboard Demonstration part of Introductory Courses:Activities
Liane Stevens, Stephen F Austin State University
This assignment is designed to introduce the silicate structures, and their significance to mineral properties, to undergraduate non-science majors in an introductory physical geology course. Magnetic ...
