There is growing body of evidence to support that students who directly experience authentic scientific research are more likely to continue onto advanced degrees and careers in Science, Technology, Engineering and Mathematics (STEM). In an effort to introduce more students to the benefits of scientific research we have drawn on an ongoing research project aimed at understanding how Corals Respond to the Environment (CRE) to develop an interdisciplinary laboratory course based on Authentic Research Experiences (ARE). A small cohort of undergraduate students enrolled in a semester-long course, entitled CREARE, perform biochemical experiments in the laboratory, analyze environmental data by R statistical software and prepared a report modeled after a research manuscript to present their work. The impact of CREARE on student learning gains and attitudes towards science is being measured, as is the impact of CREARE on participants' career choices and retention in STEM. This multidisciplinary research program addresses the impact of climate change on the health of a critically endangered coral species, ultimately leading to a better stewardship of this invaluable resource. Furthermore, CREARE offers a unique experience for students, one that may serve as a model for the development of more research-based courses, leading to improved retention in our STEM departments.

This exercise uses a number of Excel spreadsheets to calculate mineral formulae from compositional (microprobe) data. Numerous computational models are presented for most mineral groups (e.g. amphiboles, pyroxenes, micas), and students must critically evaluate which of these models is most applicable. Stoichiometry and charge balance are used to determine ferric/ferrous ratios--which is important for further applications such as geothermobarometry. Students are also asked directed questions about: compositional variation of the rock-forming mineral groups; representative complete, limited, and coupled solid solutions; site occupancy of major elements, as determined by the various computational models used; graphical representation of the calculated mineral formulae; and the composition and significance of certain varieties of these rock-forming minerals are addressed.

This is a spreadsheet that I use in petrology to walk students through calculating Rb-Sr isochrons and talking about isotope heterogeneity and sampling at various scales. The example exercise is the Tuolumne intrusive series. The file, available for download below, contains workbooks (see different tabs) with example isochrons and a spreadsheet of data for the homework problems.

This is a very short exercise designed to get students to understand how the Gibbs energy equation is used to calculate the location of a reaction in P-T space. I use it in-class and have students work on it in groups.
Besides calculating the location of one reactions, students also have to think a bit about the significance of volume and entropy with regard to mineral stability.
This exercise is very straightforward EXCEPT that students get the units (bars, Kbar, cc, etc.) confused.

In this lab activity, students learn about the relationships between sea level and glaciers during glacial and interglacial periods. First the students need to calculate the maximum sea level rise assuming all water stored in glaciers and ice caps will melt. Then, they are asked to calculate the ice sheet distribution during the last glacial maxima based on the information that sea level dropped by 125 m.

Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.

This is a field based exercise that exposes students to streams as a major agent of erosion and to methods of quantifying stream discharge by collecting data in the field. Students also apply basic navigation skills by using hand-held GPS devices and plotting longitude and latitude of the field sites under investigation.

Students will map two sections of a stream and calculate the depth, velocity, and discharge of flows required to move the stream bedload. Students will produce two cross-sectional profiles of the stream, one through a pool and one through a riffle section, and one longitudinal profile. Measurements of sediment size, depth, and velocity, will be determined at meter intervals across each cross transect. Students will also calculate the approximate cross-sectional areas across the pool and riffle sections and associated discharges. Students will also determine the stream gradient along the longitudinal profile. From these data, students will employ hydrodynamic equations to calculate the critical shear stress, and mean flow velocity required to move the bedload. Students can then calculate what the discharge and stream width would be at the time of sediment movement, and compare these data with those calculated for "normal-flow" periods.

Prior to assigning this activity in lecture, students gather information about their personal energy consumption so that they can calculate their personal carbon footprint. Specifically they need to determine the gas mileage of their vehicle, the average number of miles they drive in a month, and bring to class an electric bill and a natural gas bill from their apartment. I provide the appropriate information for students living in dorms. Their task during the class period is to assemble this information and calculate how much carbon their activities are responsible for generating. Once this portion of the assignment is complete, they investigate options for reducing their carbon emissions and the costs of those options. The pros and cons of carbon-reduction strategies form the basis for the class discussion. Lastly, students are asked to brain storm a list of potential carbon sources that are not included in this simple exercise, such as the carbon required to make the things we buy (computers, edible dinosaurs, q-tips, etc.).
