The concepts of stability and equilibrium are introduced while students learn how these ideas are related to the concept of center of mass. They gain further understanding when they see, first-hand, how equilibrium is closely related to an object's center of mass. In an associated literacy activity, students learn about motion capture technology, the importance of center of gravity in animation and how use the concept of center of gravity in writing an action scene.

Students test rocks to identify their physical properties (such as luster, hardness, color, etc.) and classify them as igneous, metamorphic or sedimentary. They complete a worksheet table to record all of the rock properties, and then answer worksheet questions to deepen their understanding of rock properties and relate them to the cavern design problem.

Given a hypothetical civil engineering scenario, student pairs are tasked to apply their knowledge of the rock cycle, rock types, rock weathering and the engineering design process to model a potential method to create a sandy beach from three rocky island shorelines. For their abrasion weathering models, they use wide-mouth lidded jars and three types of candies that serve as the testing “rocks.” They simulate both low- and high-energy weathering environments. After completing the simple weathering techniques and analyzing their observations of the results, they conclude by recommending to the island developer which rocky shoreline would be the easiest, simplest, and most cost-effective from which to create a sandy beach. A worksheet and pre/post quiz are provided.

This art history video discussion examines Auguste Rodin's "The Gates of Hell" 1880-1917, plaster (Musee d'Orsay, Paris).When the building, earlier on the site of the Musee d'Orsay in Paris, was destroyed by fire during the Commune in 1871, plans were drawn up to replace it with a museum of decorative arts. Rodin won the competition to design a great set of doors for its entry way. Although the museum was never built, Rodin continued to work on the doors. They became an ongoing project; a grand stage for his sculptural ideas. It's fitting that the plaster of this great unfinished sculpture, The Gates of Hell, is now on display at the d'Orsay, the former railway terminal that was built on this site instead of the museum of decorative arts and that, by lovely coincidence, was converted into one of the world's great art museums.

Academic libraries are undergoing evolutionary change as emerging technologies and new philosophies about how information is created, distributed, and shared have disrupted traditional operations and services. Additionally, the population that the academic library serves is increasingly distributed due to distance learning opportunities and new models of teaching and learning. This article, the first in this special issue, suggests that in today’s increasingly networked and distributed information environment, the strategic integration of open curation and collection development practices can serve as a useful means for organizing and providing structure to the diverse mass of available digital information, so that individual users of the library have access to coherent contexts for meaningful engagement with that information. Building on insights from extant research and practice, this article proposes that colleges and universities recognize a more inclusive open access environment, including the integration of resources outside of those owned or created by the institution, and a shift toward policies that consider open access research and open educational resources as part of the library’s formal curatorial workflow and collection building. At the conclusion on this article, authors Lisa Petrides and Cynthia Jimes offer a commentary on the six remaining articles that comprise this special issue on Models of Open Education in Higher Education, discussing the significant role that “open” policy and practice play in shaping teaching, learning, and scholarship in the global context of higher education.

This document is an evidence-based guide that outlines the practical and policy supports needed to enable K-12 school librarians to take on leadership roles around OER, and to support OER curation efforts by librarians and all educators.

This guide is based on a study led by ISKME (iskme.org) in collaboration with Florida State University's School of Information. The study is titled “Exploring OER Curation and the Role of School Librarians". ISKME designs guides and toolkits that help educators navigate and implement new teaching and learning practices. Grounded in research, our evidence-based guides and toolkits help articulate what actually works in real education settings—and are tailored to the unique professional learning needs of our clients and their stakeholders.

The study was made possible in part by the Institute of Museum and Library Services (www.imls.gov), under grant number LG-86-17-0035-17. The findings and recommendations expressed in this document do not necessarily represent those of the Institute of Museum and Library Services.

This course examines joint fact-finding within the context of adaptive and ecosystem-based management. Challenges and obstacles to collaborative approaches for deciding environmental and natural resource policy and the institutional changes within federal agencies necessary to utilize joint fact-finding as a means to link science and societal decisions are discussed and reviewed with scientists and managers. Senior-level federal policymakers participate

Through this activity, students come to understand the environmental design considerations required when generating electricity. The electric power that we use every day at home and work is usually generated by a variety of power plants. Power plants are engineered to utilize the conversion of one form of energy to another. The main components of a power plant are an input source of energy that is used to turn large turbines, and a method to convert the turbine rotation into electricity. The input sources of energy include fossil fuels (coal, natural gas and oil), wind, water, nuclear materials and refuse. This activity focuses on how much energy can be converted to electricity from many of these input sources. It also considers the impact of the by-products associated with using these natural resources, and looks at electricity requirements. To do this, students research and evaluate the electricity needs of their community, the available local resources for generating electricity, and the impact of using those resources.

his task is intended as a classroom activity. Student pool the results of many repetitions of the random phenomenon (rolling dice) and compare their results to the theoretical expectation they develop by considering all possible outcomes of rolling two dice. This gives them a concrete example of what we mean by long term relative frequency.

Close readings of the major British Romantic poets (Blake, Wordsworth, Coleridge, Byron, Scott, Shelley, Keats), perhaps including some of the period's important fiction writers (e.g. Mary Shelley, Walter Scott). Some attention to literary and historical context. Lecture/discussion; at least two papers.

This art history video discussion examines Eugene Delacroix's "Liberty Leading the People", oil on canvas 1830 (Musee du Louvre, Paris).

Students explore whether rooftop gardens are a viable option for combating the urban heat island effect. Can rooftop gardens reduce the temperature inside and outside houses? Teams each design and construct two model buildings using foam core board, one with a "green roof" and the other with a black tar paper roof. They measure and graph the ambient and inside building temperatures while under heat lamps and fans. Then students analyze the data and determine whether the rooftop gardens are beneficial to the inhabitants.

The Civilian Conservation Corps (CCC) was one of the most popular of Franklin Delano Roosevelt’s New Deal programs. The CCC’s mission was to conserve the natural resources of the United States while providing relief to the poor and encouraging the recovery of the economy. The program provided employment to enrolllees and financial support to their families during the Great Depression, while developing much needed conservation and infrastructure projects for a country that had been devastated by over logging and farming practices that contributed to soil erosion. Known as "Roosevelt's Tree Army," the program improved national and state parks, prevented erosion, controlled flooding, and assisted with natural disaster recovery. The unemployment rate during the Great Depression was estimated at twenty-five percent, which left a generation of young men without employment or opportunities. During its operation from 1933 to 1938, the CCC employed close to three million previously unemployed young men, although it disproportionately assisted whites. This exhibition tells the stories of the CCC’s administration and controversial policies, the men who joined, and the contributions its projects made to the history of conservation in the United States. This exhibition was created as part of the DPLA's Public Library Partnerships Project by collaborators from Mountain West Digital Library. Exhibition organizer: Anna Neatrour.

The topic of photosynthesis is a fundamental concept in biology, chemistry, and earth science. Educational studies have found that despite classroom presentations, most students retain their naive idea that a plant's mass is mostly derived from the soil, and not from the air. To call students' attention to this misconception, at the beginning of this lesson we will provide a surprising experimental result so that students will confront their mental mistake. Next, we will help students better envision photosynthesis by modeling where the atoms come from in this important process that produces food for the planet. This lesson can be completed in 50-60 minutes, with the students working on in-class activities during 20-25 minutes of the lesson. As a prerequisite, students need an introductory lesson on photosynthesis, something that includes the overall chemical equation. If students have already studied the intracellular photosynthetic process in detail, this video can still be very helpful because students often miss the big picture about photosynthesis. Materials needed include red, white and black LEGO bricks (described in downloadable hand-out) or strips of red, white and black paper plus paper clips (directions provided in downloadable hand-out). In addition to class discussions, the major in-class activity of this video involves the students' modeling with LEGO bricks or colored paper where the atoms come from in photosynthesis.

This art history video discussion examines the "Rosetta Stone", 196 B.C.E., granite (British Museum, London).

This art history video discussion examines Rosso Fiorentino's "The Dead Christ with Angels", c. 1524-7, oil on panel (Museum of Fine Arts, Boston).

Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder application is in a computer's ball-type mouse—the ball itself is a type of rotary encoder. In this activity, students experiment with two rotary encoders, including one from a computer mouse and one created using a LEGO® MINDSTORMS® NXT kit. They collect data to define and graph the relationship between the motion of the rotary encoder and its output.
