An interactive, field-based course on the environmental aspects of natural water was developed as part of STEM initiatives at a comprehensive university in the United States. The project is funded by the National Science Foundation. The course is focused on two fundamental student skills, such as hydrologic field procedures and analytical methods.…

I describe how to obtain a rather good experimental determination of the eccentricity of the Earth's orbit, as well as the obliquity of the Earth's rotation axis, by measuring, over the course of a year, the elevation of the Sun as a function of time during a day. With a very simple "instrument" consisting of an elementary sundial, first-year…

Laboratory sections of university Earth science courses provide hands-on, inquiry-based activities for students in support of lecture and discussion. Here, I compare student conceptual knowledge outcomes of laboratory sections by administering an independent concept inventory at the beginning and end of two courses: one that had a lecture and a…

We present a new laboratory activity for teaching radioactive decay by using hydrodynamic processes as an analog and an evaluation of its efficacy in the classroom. A fluid flowing from an upper beaker into a lower beaker (shampoo in this case) behaves mathematically identically to radioactive decay, mimicking the exponential decay process,…

As an aid for teaching phase equilibria to undergraduate students of igneous and metamorphic petrology, we have designed a laboratory exercise that allows them to create a phase diagram from data produced by differential scanning calorimetry. By preparing and analyzing samples of naphthalene and phenanthrene, students acquire hands-on insight into…

This article describes a one-week introduction to stochastic groundwater modeling, intended for the end of a first course on groundwater hydrology, or the beginning of a second course on stochastic hydrogeology or groundwater modeling. The motivation for this work is to strengthen groundwater education, which has been identified among the factors…

Field instruction is a critical piece of undergraduate geoscience majors' education, and fieldwork remains a major part of the work of professional geologists. Despite the central importance of field education, there exists relatively little educational research exploring how students learn to solve problems in geological fieldwork. This study…

Recently there have been newly launched ocean color satellites which target the coastlines at unprecedented scales. Science education curricula can benefit from the provision of small low-cost spectroradiometers and curriculum supplemental materials that can be incorporated in a "hands on" teaching approach to explain and demonstrate remote…

We are developing a new activity-based unit on global warming and the environment as part of the "Explorations in Physics Curriculum." We describe the current status of this unit, which focuses on helping students understand the greenhouse effect and its relationship to global warming. We outline several problems encountered in testing the unit…
