Topography - Design Challenge
Introduction - Expanded learning opportunities (ELOs) have the potential to be the great equalizer in American education. Regular participation in high quality before and afterschool learning, and enriching summer school programs have been shown to help low-income students succeed academically on par with their more affluent peers. These programs, characterized by strong school-community partnerships, can also help high-performing students stay engaged and achieve even greater levels of understanding. In short, high-quality ELOs are for everyone - and the benefits they create are critical to Nebraska's future economy. - Beyond School Bells I would like to thank Beyond School Bells as well as Nebraska Innovation Studio for providing me with the opportunity, resources, and encouragement to develop this program as an Innovation Fellow. Their willingness to give the intellectual and creative freedom to build upon my ideas and inspirations is what enabled this program to exist. I strongly believe that opportunities such as the Innovation Fellowship are planting the seeds for Nebraska's future. -Dana Hoppe, Program Creator

Concept and Purpose - Interdisciplinary Learning: This program is focused on developing fundamental STEM skills through interdisciplinary learning. The truth is that all areas of study overlap significantly in one way or another, and the cognitive skills that lead to success in one area surely extend to other areas. A recurring theme I have noticed through my personal experience of being and artist as well as a scientist is that I have heavily utilized my creative thinking abilities to solve challenging problems. Imagination and creativity, when combined with background knowledge and understanding, allow us to find solutions that often lie beyond the rigid structure often associated with mathematics and the sciences. Once we begin to see the overlap between these areas, we begin building bridges between them and new ideas and applications emerge from a formerly empty space. The concept of topography was always interesting to me. The strangeness of being able to discern the shape of the land simply from the distance between a hypnotizing assortment of lines on a flat piece of paper was immediately intriguing. How does this flat sheet of abstract shapes translate to the three-dimensional complexity of a mountain, a valley, or a bluff? Topography is the platform of this program because it is a very versatile concept and can be used to create art and models representing a diverse range of fields. The activities in this program focus on having the students follow processes often found in Computer Science. Every process they complete can be thought of as an algorithm, and when they repeat steps, it can be thought of as a loop. They are also recursively calling the same function on each resulting piece they create, mimicking the concept of dynamic programing. The permutation matrix activities will familiarize students with moving through the data in a matrix and adding data to stacks. While they are doing all of these activities, however, there will be no jargon they have to learn, and they will probably not even realize until they take their first Computer Science course that it is even related. To the students, they will simply be creating art in a new and interesting way.

Aboriginal Hand Print
(art + history; art + social studies)
"One old man in Arnhem Land remembered being carried as a child on his father's shoulders as his father climbed up a log leaning against a rock wall. His father then sprayed his hand with red ochre against the rock, leaving a stencil he could still recognize many years later. The main function of the stencils was to record people's presence and association with a site." — Aboriginal Art Online

The stenciled hand print and aboriginal style drawings help children to relate to the man from the Australian Aboriginal Culture stated above, while helping them to understand the use of line in art. A black paper with white splattered paint was used, but white paper with red (ochre) splattered paint would make a nice impression also. Construction paper crayons make bright, bold, linear designs around the hand stencil.

CropWatch is a central resource for University of Nebraska–Lincoln Extension information on crop production and pest management. It is written by Extension Educators and Specialists and produced by IANR Media in the UNL Institute of Agriculture and Natural Resources.

Information is organized into two key areas, each of which offers thousands of crop-specific articles for Nebraska producers and crop consultants:

The CropWatch newsletter, which includes timely articles published to the site's home page. New issues are published weekly during the heart of the crop production season and generally biweekly during the remainder of the year. Older articles are archived for later review.

CropWatch also includes:

- Calendar of ag events and programs
- Daily news and updates via Twitter at UNL_CropWatch (also displayed on the home page)
- Ag decision-aid tools and resources from UNL Extension
- Content tags at the end of individual stories to help you located related articles released since April 2016.
- Use the Search box in the top right of every page or the Archives to locate additional articles.
- Crop-specific production and pest management sections, with additional sites for whole farm and production systems. Use the top red-bar navigation to access specific crop, management and related topics.

"Actinobacteria are some of the most widely distributed bacteria in soils and are well known for their ability to degrade plant residues in pure culture in the laboratory. Yet, despite the importance of microbe-driven decomposition to carbon sequestration in terrestrial systems, their importance and specific activity across diverse environments in the field are unknown. Researchers recently evaluated the ecophysiological roles of Actinobacteria in rice straw residue decomposition in a series of field and microcosm experiments. They found that although Actinobacteria represented only 4.6% of the total bacterial abundance, they encoded 16% of the total carbohydrate-active enzymes (CAZymes) involved in the breakdown of carbohydrates. The researchers also found that Actinobacteria taxonomic and functional compositions were relatively stable during straw decomposition and that the importance of Actinobacteria in decomposition increased as soil fertility decreased..."

"In northern ecosystems, winter carbon loss is estimated to exceed growing season carbon uptake, primarily because of microbial decomposition. Viruses in soil alter microbial carbon cycling by affecting metabolic pathways and killing their hosts, but whether viruses are active under anoxic and sub-freezing soil conditions remains unknown. To find out, a recent study used stable isotope probing (SIP) targeted metagenomics to investigate active microbes in Alaskan Arctic peat soils under simulated winter conditions, with a particular focus on viruses and virus-host dynamics. Overall, 46 bacterial and 243 viral populations actively took up soil water labeled with ¹⁸O and respired CO₂. Active bacteria represented a small proportion of the total microbial community but were able to ferment and degrade organic matter. In contrast, a large diversity of viruses were found to be active, one-third of which were linked to active bacteria..."

The United States has a long history of activists seeking social, political, economic, and other changes to America—along with a history of other activists trying to prevent such changes. American activism covered a wide range of causes and utilized many different forms of activism. American sociopolitical activism became especially prominent during the period of societal upheaval which began during the 1950s. The African American civil rights movement led the way, soon followed by a substantial anti-war movement opposing American involvement in the Vietnam War, and later by vigorous activism involving women’s issues, gay rights, and other causes. The United States remains a land of nearly constant change, and activists play a significant role in the ongoing evolution of American democracy. It seems likely that Americans will remain enthusiastic activists in the future. This exhibition is part of the Digital Library of Georgia.

Mined phosphorus is considered essential for agriculture, especially with the need to feed the ever growing population. However, there are consequences of phosphate mining and use, including pollution at mine sites and fertilizer processing plants, heavy metal accumulation in soil where fertilizers are used, national security issues intertwined with Morocco's dominance of the world supply, and eutrophication that comes with alteration of the phosphorus cycle. Students will consider these issues, their own roles in the problem, and possible solutions in this jigsaw activity.
