Language is complicated, especially in organic chemistry. This episode of Crash Course Organic Chemistry is all about nomenclature. We'll dive into IUPAC systematic naming of organic molecules, and get to practice with the help of three trusty steps!

In this project, students interpret a high-resolution image of result from an experimental run of the Jurrasic Tank sedimentation simulator at the St. Anthony Falls Lab at the University of Minnesota. They are expected to interpret depositional environments, characterize simulated stratigraphic sections, and interpret the overall sedimentary architecture of the simulated basin. All of these observations are to put together onto a poster which is the final product of the project.

This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes a good lecture demonstration, but with a few modifications can be turned into a laboratory exercise. Key variables are "hotlinked" directly into the batch and Rayleigh models so students can adjust them to get a feel for the influence of different model parameters. The included carbon isotope data are from marbles in the Jervois region, central Australia (Cartwright et al., 1997). Oxygen isotope data are also included in the spreadsheet.

"Bathyarchaeota is a newly proposed phylum of archaeal organisms. Its diverse members inhabit anoxic environments such as hot springs, salt marshes, mangrove sediments, and the sub-seafloor. While Bathyarchaeota is believed to be an important driver of the global carbon cycle, little is known about the phylum's true metabolic potential. A new study constructed nine metagenome-assembled genomes of Bathyarchaeota using mangrove and mudflat sediments of the Futian and Mai Po Nature Reserves. Comparative analyses of these genomes expanded the role of this phylum in phototrophy, autotrophy, and the nitrogen and sulfur cycles. and findings suggested the Bathyarchaeotal subgroup can sense light and thrive in micro-oxygen conditions. The results provide insight into the metabolic abilities and diverse lifestyles of members of Bathyarchaeota and highlight the crucial role of this newly proposed phylum in global biochemical cycles..."

This activity provides students with an in-class practice of landscape interpretation using slides of beaches shown by the instructor. Students view a select number of slides and are asked to classify each beach shown using the Wright and Short Beach Classification: dissipative, reflexive, and intermediate by visually identifying landforms and processes of each beach type. The outcome of this activity is that students have practice identifying landforms and processes and applying their observations and interpretations of geomorphic features and processes for an applied purpose.
Designed for a geomorphology course

Explore the ideas and evidence that helped Charles Darwin create his theory of evolution

Hunt for prey and discover the meaning of evolutionary “fitness” in this physically active group game. In this simulation game, teams of predators equipped with genetically different “mouths” (utensils) hunt for “prey” (assorted beans). Over several “generations” of play, the fittest among the predators and prey dominate the population, modeling the evolutionary process of natural selection.

This OLogy activity shows kids that there are simple, but very helpful things they can do to protect the ocean -- even if they live nowhere near the water. The activity opens by introducing kids to Gabby, a future marine biologist who wants to study dolphins. Then it has a checklist of 14 ways kids can be ocean helpers that includes asking for tap water instead of bottled water and leaving plants and animals where they find them.

During the course of the day, students examine the high-grade metasupracrustal rocks, related gneisses, and the late Archean granitoids and mafic dikes. We have prepared a number of exercises that might be done with classes at different levels. Depending on the background and preparation of your class you might want to emphasize different learning skills specific to the class level: observation, interpretation, integration (i.e. multiple lines of evidence focused on a given problem), and synthesis (i.e. relationship to the "big picture", drawing from the corpus of geologic knowledge). We have also prepared a compilation of our key scientific results, but these are under seal and we'd like you to do the exercises first as if you were students before taking a look at the supporting evidence.

"Reperfusion of heart tissue with blood after interruption of the blood supply (ischemia) often contributes to inflammation and cell death, including a specific form of cell death called pyroptosis, which can be regulated by the protein caspase-4. The protein beclin-1 is involved in an intracellular degradation process called autophagy that can limit cell death. However, whether beclin-1 limits caspase-4-mediated pyroptosis after heart reperfusion injury remains unclear. To find out, a recent study examined the effects of beclin-1 overexpression in mouse hearts and cultured human heart cells subjected to ischemia/reperfusion. Ischemia/reperfusion increased caspase-4 activity and the expression of the pyroptosis protein gasdermin D. In contrast, beclin-1 overexpression decreased caspase-4 activity, gasdermin D expression, and the levels of the inflammation molecule IL-1β..."

"Although invisible to the naked eye, beds are teeming with microbial life, which might influence how the human body’s own microbial communities form and develop, especially in infancy. To explore this hypothesis, researchers analyzed 577 dust samples from the beds of infants, as well as 542 airway samples from a child cohort study. The diversity of bacteria and fungi detected in bed dust correlated with one another, suggesting an interplay between the two types of organisms in bed dust. Additionally, the microbial makeup of bacterial and fungal communities in bed dust was influenced by different environmental factors. Bacterial communities were influenced by type of home, living environment, sex of siblings, and pets, whereas fungal communities were influenced by type of home and sampling season. There was limited evidence of microbial transfer between bed dust and infant airways..."

To prepare for this activity, students receive background on bedforms and flow regimes in class and practice identifying and classifying bedforms from field photographs. Students are then given a map of a barrier beach/inlet/tidal delta complex in mid-coast Maine and asked to predict what bedforms they expect to find in specific sub-environments. During a subsequent field trip to the area, students observe, classify and map bedforms and relate them qualitatively to formative flows. Qualitative description and classification are supplemented by quantitative measurements of bedform morphology and orientation, and by GPS-located digital photographs. After the trip, students compare their predictions and observations of bedforms in the sub-environments, reflecting on the reasons for the differences and the evolution of their thinking. The exercise also serves to set the stage for subsequent quantitative studies of bedforms and bedload transport, as well as interpretation of sedimentary structures and clastic depositional environments in the geological record.

Students are given the task of predicting where parasequence boundaries would exist within a vertical section of the Blackhawk Formation, Utah. This activity challenges students to apply their knowledge of bedforms in order to interpret the facies they observe. The students work in groups of two as they make their observations. The vertical section consists of four main outcrops to be observed by the students. After making their observations and interpretations of these four outcrops, the students then make predictions of what should be found up section. Students begin down section by observing the lowest section of the four outcrops. The students make observations about lithology, grain size, sedimentary structures and trace fossils. After recording their observations in their field notebook the class gathers for a discussion. Students are called on randomly to discuss what they observed. The class creates a group stratigraphic column on a white board and includes their observations to the right of the drawn profile. They are then asked to interpret what facies these observations represent. The students defend their interpretations and, as a group, agree upon an interpretation. The facies interpretation is then added to the white board and the group moves to the next outcrop up section. After observing, describing and interpreting each of the four outcrops the students are challenged to use all of the information gathered thus far to predict what facies should be observed further up section. This exercise provides an opportunity for the students to make and defend observations and interpretations. They also get a sense for the importance of Walther's Law and how it relates to sequence stratigraphy.

This field mapping and map-making exercise is a capstone project for a course on Geological Maps. Over a weekend (~12 hours of field work), students collect lithologic and structural data from outcrops scattered over a one square mile area. Back in the classroom, students digitally compile their field data (outcrop, structure measurements, traverse locations) into ArcMAP. They infer geologic linework (faults and contacts) and units from this data in ArcMAP and then export these data layers into Illustrator. In Illustrator, they add ancillary map components (a cross section, description of map units, correlation diagram, map symbol legend,...) to create a final map at a 1:10,000 scale. Their maps are printed out on 11"x17" paper and saved as a pdf file. This exercise helps the students to appreciate how field data is collected and how these geologic facts are interpretively organized into a four-dimensional picture that is a geologic map.
