The unequal distribution of natural resources is the direct result of past geologic processes. Once a promising region is located, geologists use a variety of techniques to find the materials and energy that society consumes. Their tools can be as simple as a hand lens or as sophisticated as a satellite. Along the way, exploration geologists and…

The study and understanding of paleomagnetism has been pivotal in the development of the theory of plate tectonics. When it is taught in schools there are a number possible misconceptions that need to be addressed. This article attempts to provide an explanation of rock magnetism as well as strategies to avoid reinforcing some commonly identified…

Because challenges to sustainability arise at the intersection of human and biophysical systems they are inescapably embedded in social contexts and involve multiple stakeholders with diverse and often conflicting needs and value systems. Addressing complex and solution-resistant problems such as climate change, biodiversity loss, and…

Helping students understand that the scientific community's claims change through time, sometimes radically, allows them to develop a well-grounded sense of the "nature of science." Learning to reason about how scientific claims come to be accepted, and later refuted, is important for understanding the tentative nature of scientific…

The computer game sensation "Minecraft" has become a mainstay amongst school students of all ages. Anecdotally, at Geoscience Australia, we have observed that "Minecrafters" often draw comparisons between their Minecraft experiences and the real world. For some students, the line between reality and fantasy is blurred. At the…

Interactive Historical Vignettes (IHVs) can serve as introductions to scientific content, pique students' interest, and reveal the nature of science to students (Clary and Wandersee 2006). Additionally, pivotal episodes in the life of a scientist can reveal the humanness of science, and the cultural and societal constraints in which the scientist…

Halifax Independent School is a small K-9 school where children learn in multi-age groups and in a setting where all the core subjects are integrated into the study of interesting themes such as Oceans, Nova Scotia, and Living Things. These themes last a whole year, involve the whole elementary school, and are designed to cover traditional subject…

There has been little discussion regarding the design of geology courses (and programs) to be inclusive of students with an autism spectrum disorder (ASD). Here, we outline challenges instructors may encounter when teaching geology courses with field components that include students with an ASD and describe solutions we have found to be successful…

This article describes activities in which students sample, investigate, classify, and compare characteristics (i.e., texture, color, density, porosity) of local soils, evaluating whether the soils are healthy or at risk. Students investigate correlations between geology and geography, predict which soil types may go extinct in their state, and…

There are obvious differences between teaching postsecondary courses during the mid-twentieth century and teaching those same courses in the twenty-first century. Today's students--particularly at two-year institutions -- are often employed full-time and must balance their course loads with "family/social commitments." The "power…

The idea of building sand castles evokes images of lazy summer days at the beach, listening to waves crash, enjoying salty breezes, and just unplugging for a while to let our inner child explore the wonderful natural toys beneath our feet. The idea of exploring caves might evoke feelings and images of claustrophobia or pioneers and Native…

High-accuracy Global Positioning System (GPS) has become an important geoscientific tool used to measure ground motions associated with plate movements, glacial movements, volcanoes, active faults, landslides, subsidence, slow earthquake events, as well as large earthquakes. Complex calculations are required in order to achieve high-precision…

As our closest celestial neighbor, the Moon is a familiar and inspiring object to investigate using a small telescope, binoculars, or even photographs or one of the many high quality maps available online. The wondrously varied surface of the Moon--filled with craters, mountains, volcanic flows, scarps, and rilles--makes the Moon an excellent…

This column focuses on promoting learning through assessment. The formative assessment probe in this month's issue can be used as an initial elicitation before students are introduced to the formal concepts of weathering and erosion.

Stromatolites are the rocklike structures produced by "microbial mats"--communities of microorganisms only a few millimeters thick--as they trap, bind, or precipitate minerals. This article provides activities and assessment ideas to help teachers incorporate stromatolites in their classrooms. It relates the study of stromatolites to the…
