Introduction to seismic theory, measurements and processing of seismic data to final focussed image for geological and/or physical interpretation.This course deals with the most important aspects of reflection seismics. Theory of seismic waves, aspects of data acquisition (seismic sources, receivers and recorders), and of data processing (CMP processing, velocity analysis, stacking, migration) will be dealt with. The course will be supplemented by a practical of 6 afternoons where the students will see the most important data-processing steps via exercises (in Matlab).

The development of systems and network concepts for students can begin with this highly interactive inquiry into cell phone networks. Cell phones serve as a handy knowledge base on which to develop understanding. Each cell phone represents a node, and each phone’s address book represents an edge, or the calling relationships between cell phones. Students conceptualize the entire cell phone network by drawing a graphic that depicts each cell phone in the class as a circle (node) connected by directional lines (edges) to their classmate’s cell phones in their address book. Students are queried on the shortest pathway for calling and calling pathways when selected phones are knocked out using school and classroom scenarios.

Students then use a simulation followed by Cytoscape, visually graphing software, to model and interrogate the structure and properties of the class’s cell phone network. They investigate more advanced calling relationships and perturb the network (knock out cell towers) to reexamine the adjusted network’s properties. Advanced questions about roaming, cell towers and email focus on a deeper understanding of network behavior. Both the paper and software network exercises highlight numerous properties of networks and the activities of scientists with biological networks.

Target Audience:
This is an introductory module that we recommend teaching before each of our other modules to give students a background in systems. This module can be applied easily to any content area and works best as written for students between 6th and 12th grades but can be adapted for other ages. The lessons work best when in-person with students. If you are looking for an Introduction to Systems for remote learning, please use our Systems are Everywhere module.

In spring 2020, the world was hit by a pandemic that spread globally by March, causing universities and most of the world to move to remote means. Summer field camps, long hailed as a rite of passage in the geosciences, were cancelled throughout the US. The community moved quickly, with NAGT developing remote learning tools and arranging for sharing and collaboration between instructors and institutions. As such, UNAVCO (GETSI) and University of Northern Colorado embarked on a data collection campaign for a summer field course entitled "Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes" -- originally slated for in-person teaching. The team collected GNSS data, drone imagery for use in structure from motion (SfM), and terrestrial laser scanning (TLS) from a site near Greeley, Colorado on the Poudre River. In this assignment, students analyze TLS data in a similar manner as previously done for the SfM unit conducted previously in the course. Students compare and contrast the SfM and TLS datasets.
Day 7 - This activity is part of the 2-week remote field course Geoscience Field Issues Using High-Resolution Topography to Understand Earth Surface Processes

Interactive Lecture Demonstrations to illustrate the nature of torques and on the balancing of torques in static equilibrium.

This activity is designed to provide qualitative understanding of the Work-Energy Theorem. Students are expected to have read introductory material regarding the theorem, and are tested on this with a short online quiz prior to class. After a brief discussion a "warm-up" demonstration is conducted with student participation. A question is then posed regarding the height a "Hopper Popper" will reach if launched from a thumb instead of a hard flat surface. After initial responses are presented, discussion groups are formed to achieve consensus and provide justification of conclusions. This is followed by a confirming demonstration with surprising results.

This activity is an interactive demonstration of the concept of density with a guided inquiry component.

Open tube resonators of nearly identical length produce sound waves with frequencies very close together. The difference between the two frequenciesy is the beat note frequency heard when two resonators (musical intruments)are slightly out-of-tune.

This activity is a guided exploration of how static electricity works and how it relates to lightning.

This activity is a classroom investigation where student observe several properties of water; adhesion and cohesion. They will transfer this knowledge to predicting other materials that will have adhesion with water molecules.

To have students gain a better understanding that representing the United States abroad is an extraordinarily dangerous job. This lesson provides students with a hands-on history lab where participants step into the roles of President Carter and his advisors, work with formerly classified primary source documents, and collaborate to tackle one of history’s greatest challenges. Reveal to students how, in the wake of a successful 1979 revolution by Islamic fundamentalists against the pro-American Shah of Iran, the United States became an object of virulent criticism and the U.S. Embassy in Tehran was a visible target.

In this field activity students ponder sustainability issues such as point and non-point sources of pollution (including personal contributions), impacts of pollution, and potential mitigations.

Students complete several short, in-class exercises related to understanding isopach maps. We use Play-Doh models to illustrate features revealed in the isopach maps and to support student understanding of the relationship between geology, isopach maps, and structure contour maps. I also show several examples of isopach maps of geologically interesting features to illustrate how and why we use them.

An interactive applet and associated web page that demonstrate isosceles triangles (two sides the same length). The applet presents a triangle where the user can drag any vertex. As the vertex is dragged the others move automatically to keep the triangle isosceles. The angles are also updated continuously to show that the base angles are always congruent. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

The Horses of Saint Mark have a long itinerary through space and time. On this lesson, we will through the visualisation of their whole itinerary to make the students of their relation with powerful states on their whole history.

O Quiz Meio Ambiente, constitui-se de um jogo da roleta, organizada no power-point, abordando os temas discutidos no decorrer das atividades trabalhadas com educandos da EJA (Ensino Médio) sobre a temática dos Resíduos Sólidos. O jogo propõe contextualizar as informações inerentes a realidade dos educandos, além de desenvolver um espírito participativo e colaborativo entre as equipes, que se esforçam para responder ao quiz e assim vencer o jogo.

Make sparks fly with John Travoltage. Wiggle Johnnie's foot and he picks up charges from the carpet. Bring his hand close to the door knob and get rid of the excess charge.

This is an online geologic mapping activity designed to mimic the experience of conducting a geologic mapping project over several days in a field area. Students download a physical topographic basemap and then plot structural data and interpret rock units and their placement on the map based on a collection of gigapan photos. Finally, students answer a series of questions based on the map pattern and some U-Pb analytical data to determine the chronology of deformation. The exercise requires students to integrate various fields of geology to piece together the geologic history of this hypothetical region, loosely based on the North American Cordillera.
