Student Experience 14: "So What?", Ana K. Houseal

Ana K Houseal

This activity is designed to encourage students to question their own learning and the implications that learning has to them as well as to the broader community. For example: How will this knowledge, these skills and these concepts influence individual lives and the life of the community? What impact does this have on the environment? The activity also helps teachers to reflect about the relevance of lessons within their own curriculum and appropriateness of their teaching strategies. And it is a way for students to take the concepts and apply them in new ways making them more relevant.

Student Experience 03: Photo Points, Ana K. Houseal

Ana K Houseal

Students learn about using photogrammy (making multiple identical images of a location taken with a camera whose relative position is known to a certain degree of accuracy) to monitor change over time. This set of activities within the following lesson will help students learn about the process of collecting identical images and its importance, and practice collecting images from set locations, first in their own environments and then in the field. With this background, students can participate in photo point data collection during their expedition on Geology Day, and have a better understanding of the importance of this data collection. …

Student Experience 02: Powers Of Ten Background, Ana K. Houseal

Ana K Houseal

Powers of Ten (P10) refers to scale. This scale can be an excellent tool to use when framing observations. In other words, P10 is a way of putting objects being observed into context using size as the focal point. Once students understand the terminology, it can be used to both communicate and focus attention.

Student Experience 12: Using The Ir Thermometer To Develop Answerable Questions, Ana K. Houseal

Ana K Houseal

Students learn about and use IR thermometers in the classroom or some place on the school grounds to develop answerable questions. After developing the questions, they perform brief investigations to answer their questions and share their findings with their classmates.

Student Experience 04: Mammoth Hot Springs Photo Points, Ana K. Houseal

Ana K Houseal

Photos taken over time from set photo points can help to increase understanding of terrace formation and concretely map the movement of microbial communities. Now, and in the future, researchers can use these high quality photos to help answer questions about things such as microbial mat migration, possible shifts in water flow, and formation of terracing through travertine precipitation/deposition. In the meantime, visitors and students will have access to these photos and can compare visible changes themselves.

Background 4: Student Experience Lesson - Systems Study, Ana K. Houseal

Ana K Houseal

This lesson helps students observe, integrate and articulate their knowledge of a familiar earth system by considering how the different parts of the system interact to keep it in balance. Students first explore the word “system” and then apply the concept of systems to a familiar natural environment. Students will create a collage that is a representation of this system through discussion, further inquiry, and investigation.

Student Experience 08: Starrs Temperature Tools, Ana K. Houseal

Ana K Houseal

Students get a chance to use various temperature tools to explore the Celcius temperature scale. They also will explore the differences in the temperature tools and determine and share with the whole group which tools are appropriate for measuring temperature in different situations.

Student Experience 06: Prolonged Observations, Ana K. Houseal

Ana K Houseal

Students participate in an exercise conducting a prolonged observation of a known object. Students will compare how their observations change as the observation time passes. This activity meant to teach the importance of careful, sustained observation as a "scientific tool".

Student Experience 09: Social Applications For Power Of Ten (P10), Ana K. Houseal

Ana K Houseal

In this lesson, students are asked to observe and record their observations of an object at a specific distance, either moving away from or toward at specific powers of ten intervals. Discussions of their observations may help students to see how detail changes with perspective, and how different jobs, including science, might require focus on different powers of ten.

Student Experience 05: The Candle, Ana K. Houseal

Ana K Houseal

Sometimes objects turn out to be something other than what we think we are observing. Learning to make careful observations provide the basis for students to engage in further observations of objects that are both familiar and unfamiliar. In this lesson, students make observations while the teacher manipulates an object that appears to be a candle. This leads to the exploration of the differences between observations and inferences.

Fluorescent Chrysotile From Sterling Hill, New Jersey, James A. Van Fleet, Earl R. Verbeek

James A. Van Fleet

Minerals of the serpentine group, notably chrysotile and to a lesser extent lizardite, are widely present at both Franklin and Sterling Hill. They are late-stage hydrous magnesium silicate minerals that formed by hydrothermal alteration of earlier species, among them willemite and tephroite, and are also common components of hydrothermal veins cutting the ore bodies and the enclosing marble (Dunn, 1995). Although long recognized in the area (Fowler, 1825), local serpentine was not documented as a fluorescent mineral until 2004, when a brief description of a fluorescent serpentine from Franklin appeared in The Picking Table (Cianciulli, 2004). In the present paper, …

The Curse Of Rafinesquina: Negative Taphonomic Feedback Exerted By Strophomenid Shells On Storm-Buried Lingulids In The Cincinnatian (Katian, Ordovician) Series Of Ohio, Rebecca Freeman, Benjamin Dattilo, Aaron Morse, Michael Blair, Steve Felton, John Pojeta

Benjamin F. Dattilo

Thousands of lingulid brachiopods were found clustered beneath hundreds of individual valves of the strophomenid brachiopod Rafinesquina in the Upper Ordovician of Ohio. This association suggested a relationship between the two brachiopods, but the nature of this relationship was unclear. We utilized serial thin sectioning to examine these brachiopods and to determine the origin of the bed in which they were found. Sedimentary structures, mixed taphonomies, and stratigraphic and paleogeographic setting suggest that the lingulids occupied a hiatal concentration that had previously been reworked, but not significantly transported, by tropical storms. The final burial event was a storm that exhumed …

The Impact Of Host Rock Geochemistry On Bacterial Community Structure In Oligotrophic Cave Environments, Hazel Barton, Nicholas Taylor, Michael Kreate, Austin Springer, Stuart Oehrle, Janet Bertog

Hazel Barton

Despite extremely starved conditions, caves contain surprisingly diverse microbial communities. Our research is geared toward understanding what ecosystems drivers are responsible for this high diversity. To asses the effect of rock fabric and mineralogy, we carried out a comparative geomicrobiology study within Carlsbad Cavern, New Mexico, USA. Samples were collected from two different geologic locations within the cave: WF1 in the Massive Member of the Capitan Formation and sF88 in the calcareous siltstones of the Yates Formation. We examined the organic content at each location using liquid chromatography mass spectroscopy and analyzed microbial community structure using molecular phylogenetic analyses. In …

Changes In Beach Gravel Lithology Caused By Anthropogenic Activities Along The Southern Coast Of Lake Michigan, Usa, Zoran Kilibarda, Nolan Graves, Melissa Dorton, Richard Dorton

Zoran Kilibarda

The southern coast of Lake Michigan is the most urbanized and most densely populated area in the Great Lakes region. Development of steel mills, harbors, and municipalities in NW Indiana and in NE Illinois in the last century and a half altered the nearshore environment so much that native beach gravel (>8 mm) now exist only in the exhumed paleo-beach remnants from the Nipissing Phase (~4,500 years ago) of Lake Michigan. Native gravel, collected from paleo-beach remnants at Mount Baldy Dune and Beach House Blowout, contain predominantly beach shingle, very platy siltstones (71–78 %), with secondary crystalline pebbles (18 …

Forum On The Flood/Post-Flood Boudary, Marcus R. Ross

Marcus R. Ross

The location of the Flood/post-Flood boundary is an important issue for Flood geology because it is the starting point for a host of research questions. Many papers have been published on this topic, but its placement is still controversial. Three main views are advocated: a low Flood boundary in the Paleozoic or below, a boundary at or near the Cretaceous-Tertiary boundary (now the Cretaceous/Paleogene boundary), and a variable boundary towards the upper Cenozoic but with each geographical area to be evaluated on its merits.

In 2012, Marcus Ross, published a biostratigraphic analysis and argued that a Flood/post-Flood boundary at or …

Locating Cryptotephra In Sediments Using Fluid Imaging Technology, Robert D'Anjou, Nicholas L. Balascio, Raymond S. Bradley

Raymond S Bradley

We report a new approach to locate and quantify cryptotephra in sedimentary archives using a continuously-imaging Flow Cytometer and Microscope (FlowCAM_). The FlowCAM rapidly photographs particles flowing in suspension past a microscope lens and performs semi-automated analysis of particle images. It has had primarily biological applications, although the potential sedimentological applications are numerous. Here we test the ability of this instrument to image irregularly shaped, vesicular glass shards and to screen sediment samples for the presence of cryptotephra. First, reference samples of basalt and rhyolite tephra (sieved <63>microns) were analyzed with the FlowCAM, demonstrating the ability of the instrument to …
