Students use aerial photography combined with field observation to interpret the geology of a megascopic anticline-syncline pair exposed in the Ouachita Mountains of central Arkansas. This project focuses on the integration of remotely-sensed data with direct observation to develop and test hypotheses regarding the geology and structure of a well-defined field area. Students construct a geological map and cross-section that synthesize their observations and illustrate the geology of the field area.

Students experiment with a new material—aerogel. Aerogel is a synthetic (human-made) porous ultra-light (low-density) material, in which the liquid component of a gel is replaced with a gas. In this activity, student pairs use aerogel to simulate the environmental engineering application of cleaning up oil spills. In a simple and fun way, this activity incorporates density calculations, the material effects of surface area, and hydrophobic and hydrophilic properties.

This contemplative practice inquires into the complex web of interdependencies linking global climate change, the War on Terror, Afghan poppy production, opiate addiction, and food security through the lens of systems theory. The exercise challenges students to consider these linkages not only conceptually but also somatically and emotionally.

African American History and Culture contains 10 modules starting with African Origins - History and Captivity and continuing through Reconstruction. Openly-licensed course materials developed for the Open Educational Resources (OER) Degree Initiative, led by Achieving the Dream https://courses.lumenlearning.com/catalog/achievingthedream.

This collection uses primary sources to explore the experiences of African American Soldiers in World War I. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

As a historic unit of the National Park Service, the Mary McLeod Bethune Council House is listed in the National Register of Historic Places. The site also is within the boundaries of the Logan Circle Historic District. This lesson is based on the Historic Resources Study for Mary McLeod Bethune Council House National Historic Site, as well as other materials on Bethune and the National Council of Negro Women. The lesson was written by Brenda K. Olio, former Teaching with Historic Places historian, and edited by staff of the Teaching with Historic Places program and Mary McLeod Bethune Council House National Historic Site.

Learn to distinguish between exponential and logistic growth of populations, identify carrying capacity, differentiate density-dependent and density-independent limiting factors, apply population models to data sets and determine carrying capacity from population data. Make predictions on graphs and interpret graphical data to analyze factors that influence population growth.

After catastrophic flooding in New Orleans destroyed two hospitals, the Southeast Louisiana Veterans Health Care System is planning a replacement facility that will incorporate resilience against future extreme events.

Widespread damage from flooding at the Texas Medical Center in Houston revealed the complex's vulnerabilities. Implementing a long-term hazard mitigation plan is reducing future risks.

This comprehensive guide to the Paleontology section of OLogy, the Museum's science Web site for kids, explains how after-school educators can make the most of the site. It focuses on dinosaurs because that's what kids are most familiar with. An introduction to the Big Ideas in Paleontology brings educators up to speed on how scientists study early life on Earth, what kind of information the fossil record contains, and why dinosaurs are not extinct. A Site Map shows where to locate all Paleontology resources, from stories to quizzes to hands-on-activities. Paleontology units offer ways to combine different types of resources around a topic. Follow-up questions encourage inquiry-based learning. Wrap-Up Paleo Projects suggests fun ways to wrap up any of these units. A Links and Resources section lists recommended paleontology-related books and Web sites for educators and for kids. A glossary of paleontological terms wraps up the guide.

In this activity about light and perception, learners discover how a flash of light can create a lingering image called an "afterimage" on the retina of the eye. Learners will be surprised when they continue to see an image of a bright object after staring at it and looking away. Use this activity to introduce learners to principles of optics and perception as well as to explain why the full moon often appears larger when it is on the horizon than when it is overhead. This lesson guide also includes a few extensions like how to take "afterimage photographs."

Western Mining History presents a short history of the famous gunfight in the OK Corral, an iconic legend of the Old West. Western Mining History is an historical site that provides databases, information on mining, mining towns, gold and Photos and maps of the western United States. Consider becoming a member or making a donation to help further the work of the site.

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes). The program is structured for use in a variety of settings, including astronomy days, summer camps, or year-long afterschool programs. Although session activities build concepts sequentially, each session activity is designed to be freestanding as not all participants may attend every session. A manual provides background information and descriptions of how to conduct each activity. A companion website provides additional information and resources for the program leader.

After the Ice: Our Food discusses changes in historic food sources for Arctic Native Americans. Global climate change is altering yearly cycles of both ice coverage and depth in the Bering Sea. Changes in the ice affect the way local native groups hunt in order to feed their community.

This 7-minute video illustrates how the historic homeland for Arctic Native Americans is being affected by climate change. Shorefast ice and pack ice are present for a shorter part of the year. This has profound affects on the way of life in the Bering Sea region, to the point where the community may have to relocate.

This video discusses how the historic way of life for Arctic Native Americans has changed. Global climate change is altering the ice cycle (yearly coverage, depth, and persistence) in the Bering Sea and weather patterns. Changes in the ice affect the way local native groups are able to hunt for food, and maintain their community.

All biological cells require the transport of materials across the plasma membrane into and out of the cell. By infusing cubes of agar with a pH indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells. Then, by observing cubes of different sizes, you can discover why larger cells might need extra help to transport materials.

Building on Complex Adaptive Systems theory and basic Agent Based Modeling knowledge presented in SPM4530, the Advanced course will focus on the model development process. The students are expected to conceptualize, develop and verify a model during the course, individually or in a group. The modeling tasks will be, as much as possible, based on real life research problems, formulated by various research groups from within and outside the faculty.
Study Goals The main goal of the course is to learn how to form a modeling question, perform a system decomposition, conceptualize and formalize the system elements, implement and verify the simulation and validate an Agent Based Model of a socio-technical system.

In this unit, students learn about the form and function of the human heart through lecture, research and dissection. Following the steps of the Legacy Cycle, students brainstorm, research, design and present viable solutions to various heart conditions as presented through a unit challenge. Additionally, students study how heart valves work and investigate how faulty valves can be replaced with new ones through advancements in engineering and technology. This unit demonstrates to students how and why the heart is such a powerful organ in our bodies
