Minerals and metals are part of everyday existence, including in the air people breathe. They are either in, or have a hand in creating, nearly all of consumer products. As essential as they are, minerals and metals are too often unseen, unappreciated, and unnoticed. In the teaching of preservice primary and secondary teachers as well as high…

Minerals are commonly taught in ways that emphasize mineral identification for its own sake or maybe to help identify rocks. But how do minerals fit in with other science content taught? The author uses mineral formulas to help Earth science students wonder about the connection between elements, compounds, mixtures, minerals, and mineral formulas.…

For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

This article aims to introduce the lanthanides (also known as the lanthanoids) to teachers and their students. The lanthanides are not mere "footnotes" at the bottom of the periodic table but make up a group of interesting and unique metallic elements. They and their compounds have widespread technological applications that have become…

General chemistry and introductory chemistry students were presented with a laboratory exploration for the determination of the mass percent of copper in rock and mineral samples. They worked independently in the laboratory, which involved multiple lab (pipetting, preparing standard solutions by quantitative dilution, recording visible spectra…

This article describes a field course in Cornwall looking at mineral processing with the focus on the chemistry involved. The course was split into two parts. The first looked at tin mining based around Penzance. This involved visiting mines, hunting for mineral samples, carrying out a stream survey and visiting the Camborne School of Mines…

Rocks and other Earth materials are included in national, state, and local standards. For example, "A Framework for K-12 Science Education" (NRC 2012) contains topics related to Earth systems, which include the hydrosphere, atmosphere, biosphere, and geosphere. By second grade, students should be able to describe how most areas where…

A laboratory experiment is described in which a simple characterization of a historical lime mortar is made by the determination of its approximate composition by a gravimetric method. Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) are also used for the qualitative characterization of the lime mortar components. These…

When the challenge of adapting curriculum to meet the requirements of the Common Core State Standards were presented, this author immediately sought out the assistance of experts in another field: the school library staff. It was apparent that staff needed to practice the beneficiation of the current curriculum to meet the CCSS requirements.…

The study of electricity and magnetism is fundamental to all first-year physics courses. Developing simple electricity laboratory experiences that are open ended and inquiry based can be difficult. We wished to create a lab experiment where the students have some control over the experimental design, data analysis is required, and students…

Using an ALTA II reflectance spectrometer, the USGS digital spectral library, graphs of planetary spectra, and a few mineral hand samples, one can teach how light can be used to study planets and moons. The author created the hands-on, inquiry-based activity for an undergraduate planetary science course consisting of freshman to senior level…

The primary focus in managing asthma is the control of inflammation, as asthma is an inflammatory disease. Because of this chronic airway inflammation, the lungs of asthmatic patients are exposed to oxidative stress due to the generation of reactive oxygen- and nitrogen species (ROS and NOS). Oxidative stress therefore plays an important role in…

This article presents an activity that focuses on helping students investigate the formation of rocks, minerals, and gemstones. Students describe visual, textual, and physical properties of various specimens of minerals. Using compare and contrast skills, students can classify the primary types of rock, ask questions about the Earth's inner…

Investigations that integrate concepts from geological sciences with biology and chemistry are rare. The authors present an investigation that introduces high school students to microbe-mineral interactions by tying together anaerobic respiration, reduction reactions, metal ion solubility, and groundwater pollution. During the investigation,…

Decades ago Buerger described and later Palmer reviewed stuffed silica crystal structures widely used by mineralogists. Many publications and books have discussed common crystal structures in terms of close-packing of one set of atoms or ions (P sites) with other atoms or ions in tetrahedral (T) or octahedral (O) sites. Douglas and Ho described…
