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.

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.

Teaching Climate Science by Studying Misinformation part of Climate Change:Activities
Daniel Bedford, Weber State University
Students critically evaluate the arguments about climate change raised in a climate contrarian newspaper op-ed. This strengthens student critical thinking and content knowledge.

Is that true? part of Oceanography:Activities
Steve Hovan, Indiana University of Pennsylvania-Main Campus
Ask students to research the "truth" behind statements from recent news articles and provide their opinion about what is "true". These assignments can be done as often as the instructor feels ...

Graphing Tides part of Oceanography:Activities
Martin Farley, University of North Carolina at Pembroke
Student graphing of high and low tide from locations showing the three tide types (diurnal, semi-diurnal, and mixed) and the Bay of Fundy (tidal amplitude increased by resonance). Students recognize that not all ...

El Niño and Ocean-Atmosphere Interactions in the Tropical Pacific part of Oceanography:Activities
Tim Cook, Worcester State University
This activity investigates the oceanographic and climatic characteristics of El Niño/La Niña (ENSO) events using observational data from moored ocean buoys in the tropical Pacific Ocean. Data are obtained from ...

Atmospheric Carbon: Can We Offset the Increase? part of Oceanography:Activities
Joceline Boucher, Maine Maritime Academy
This activity lets students discover first hand how the big issues in climate change -- here, the increase in atmospheric CO2 and the utility of carbon offsets -- can be understood through measurement, application ...

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.

Google Earth Investigations of Folded and Faulted Landforms part of Geodesy:Activities
Hillary Hamann, University of Denver
This activity utilizes Google Earth (the free downloadable version) to investigate folded and faulted landscapes and to review crustal deformation processes and associated landform features.

Selecting Sites for Renewable Energy Projects part of Teaching Methods:Teaching with Google Earth:Examples
Glenn Richard, SUNY at Stony Brook
Students use Google Earth to investigate appropriate locations for a variety of renewable energy projects in the United States. These include projects that use solar energy, bioenergy, hydroelectricity, tidal power, wind energy, wave energy, and geothermal energy.
