For every object that ends up in a library or museum collection – whether it’s a manucript, a photograph, or something more approaching the concept of “art” – there is a narrative, a story that gets told. The story a visitor to an exhibit ends up hearing, of course, is dependent upon who is telling the story and the slant of their own perspective. When the subject of the exhibit is Native Americans in the Upper Midwestern United States during the extraordinary upheaval of the 19th century, one must be particularly careful about the story being told since the narrative that largely exists is one of cultural denouement, of endings, as told by a colonizing population to its descendants. The dominant narrative of the demise of traditional Native American culture in the face of colonization, conversion to Christianity, confinement to reservations and economic collapse is, however, not the only story that can be told. The accounts of the lives of Native Americans during the 19th century that are told by Native peoples themselves are strikingly different to those recounted in history books, movies, and all too frequently in museums. Rather than narratives solely recounting destruction and demise, Native stories about Native history tend to focus on what White Earth Ojibwe scholar Gerald Vizenor has called survivance – a narrative incorporating themes of survival and resistance that insist on the inclusion of the Native presence. The following is an exhibit of resources that can be found within the Digital Public Library of America retold through the lens of Native American survivance in the Minnesota region. Within are a series of objects of both Native and non-Native origin that tell a story of extraordinary culture disruption, change and continuity during 19th c., and how that affects the Native population of Minnesota today. This exhibit was created by the Minnesota Digital Library.

For many Americans, their fondest memories revolve around a library card. From searching through the stacks, to getting a return date stamped on the back of a new favorite book, libraries are a quintessential part of how Americans learn and engage with their local communities. Since this country’s founding, public libraries have received broad and consistent popular support for their democratic missions and services. The ability to access free information has become a core ideal of what it means to be an American citizen, despite periods of historic inequality. Libraries help make this access possible by placing public benefit at the center of their work and continually adapting their strategies to meet changing public needs over time. This exhibition tells the story of the American public library system, its community impact, and the librarians who made it possible—from the founding of the first US libraries through the first one hundred years of service. This exhibition was created as part of the DPLA’s Public Library Partnerships Project in collaboration with partners and participants from Digital Commonwealth, Digital Library of Georgia, Minnesota Digital Library, Montana Memory Project, and Mountain West Digital Library.

Through six lesson/activity sets, students learn about the functioning of sensors, both human and robotic. In the activities, student groups use LEGO MINDSTORMS(TM) NXT robots and components to study human senses (sight, hearing, smell, taste, touch) in more detail than in previous units in the series. They also learn about the human made rotation, touch, sound, light and ultrasonic sensors. "Stimulus-sensor-coordinator-effector-response" pathways are used to describe the processes as well as similarities between human/animal and robotic equivalent sensory systems. The important concept of sensors converting/transducing signals is emphasized. Through assorted engineering design challenges, students program the LEGO robots to respond to input from various LEGO sensors. The overall framework reinforces the theme of the human body as a system with sensors that is, from an engineering perspective. PowerPoint® presentations, quizzes and worksheets are provided throughout the unit.

Four lessons related to robots and people present students with life sciences concepts related to the human body (including brain, nervous systems and muscles), introduced through engineering devices and subjects (including computers, actuators, electricity and sensors), via hands-on LEGO® robot activities. Students learn what a robot is and how it works, and then the similarities and differences between humans and robots. For instance, in lesson 3 and its activity, the human parts involved in moving and walking are compared with the corresponding robot components so students see various engineering concepts at work in the functioning of the human body. This helps them to see the human body as a system, that is, from the perspective of an engineer. Students learn how movement results from 1) decision making, such as deciding to walk and move, and 2) implementation by conveying decisions to muscles (human) or motors (robot).

Through four lessons and four hands-on associated activities, this unit provides a way to teach the overarching concept of energy as it relates to both kinetic and potential energy. Within these topics, students are exposed to gravitational potential, spring potential, the Carnot engine, temperature scales and simple magnets. During the module, students apply these scientific concepts to solve the following engineering challenge: "The rising price of gasoline has many effects on the US economy and the environment. You have been contracted by an engineering firm to help design a physical energy storage system for a new hybrid vehicle for Nissan. How would you go about solving this problem? What information would you consider to be important to know? You will create a small prototype of your design idea and make a sales pitch to Nissan at the end of the unit." This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics.

Students are presented with an engineering challenge: To design a sustainable guest village within the Saguaro National Park in Arizona. Through four lessons and six associated activities, they study ecological relationships with an emphasis on the Sonoran Desert. They examine species adaptations. They come to appreciate the complexity and balance that supports the exchange of energy and matter within food webs. Then students apply what they have learned about these natural relationships to the study of biomimicry and sustainable design. They study the flight patterns of birds and relate their functional design to aeronautical engineering. A computer simulation model is also incorporated into this unit and students use this program to examine perturbations within a simple ecosystem. The solution rests within the lessons and applications of this unit.

For many Americans today, snapping a photo is as easy as pulling out a smartphone. However, that digital photo is the result of decades of experimentation and development, from first forays into bulky and difficult-to-use professional cameras to instant-photo Polaroids. Since the advent and eventual commercialization of photography throughout the nineteenth century, cameras have continuously redefined the American public’s conception of how images and history can be captured and shared. Looking to the early cameras of the 1800s to today’s cell phones and social networking apps, this exhibition explores how the personal camera has shaped American consciousness and culture over the course of its development. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Dr. Joan E. Beaudoin's course "Metadata in Theory and Practice" in the School of Library and Information Science at Wayne State University: Ellen Tisdale, Rachel Baron Singer, Amanda Seppala, Michell Geysbeek, and Jay Purrazzo.

December 2013 marks the 80th anniversary of the end of Prohibition, the period between 1920 – 1933 when the manufacture, transport and sale of intoxicating liquors was illegal in the United States. The 18th Amendment to the Constitution, ratified in 1919, was the crowning achievement of a temperance movement that had been building in this country since the late 1700s. Alcohol consumption had peaked to a high of about 7 gallons per person in the early 1800s (compared to less than 3 gallons today), with recognized health and societal consequences. But the new laws were difficult to enforce, due to general unpopularity and the profits that could be made through circumventing the law. Demand for alcohol remained high, and organized crime and corruption flourished. Loopholes and exemptions also allowed home wine production, and prescriptions for medical alcohol rose dramatically. Enforcement difficulties, popular resistance, and economic pressures associated with the Great Depression all contributed to efforts to repeal Prohibition. In 1933, the 21st Amendment ended national prohibition and returned responsibility for alcohol regulation to the states. The Kentucky Digital Library and DPLA would like to thank the contributing institutions for providing the unique content and metadata featured in Indomitable Spirits: Prohibition in the United States. Texts, research, and compilation by University of Kentucky Libraries employees Sarah Dorpinghaus, Beth Kraemer, Kathryn Lybarger, Mary Molinaro, Judy Sackett, and Stacy Yelton.

Students learn about complex networks and how to use graphs to represent them. They also learn that graph theory is a useful part of mathematics for studying complex networks in diverse applications of science and engineering, including neural networks in the brain, biochemical reaction networks in cells, communication networks, such as the internet, and social networks. Students are also introduced to random processes on networks. An illustrative example shows how a random process can be used to represent the spread of an infectious disease, such as the flu, on a social network of students, and demonstrates how scientists and engineers use mathematics and computers to model and simulate random processes on complex networks for the purposes of learning more about our world and creating solutions to improve our health, happiness and safety.

Our planet is precious. Connecting to our world and becoming aware of our surroundings and ways we can keep Earth beautiful can be empowering to students and adults alike! Our goal with this project is to encourage and empower students to reduce waste in our classrooms, our school, our community and beyond!

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

Consistent housing is a continual issue for our community, evidence of this is readily observable in the neighborhoods surrounding our classrooms. Over the course of 15 classroom hours, students will be exploring how they can insulate structures to protect from extreme hot and extreme cold using recycled and/or repurposed materials.

Students will make observations and collect data related to temperature. Student findings will be communicated through science journals, student generated models (charts, 3D structures, drawings, etc.).

Students learn and use the properties of light to solve the following challenge: "A mummified troll was discovered this summer at our school and it has generated lots of interest worldwide. The principal asked us, the technology classes, to design a security system that alerts the police if someone tries to pilfer our prized possession. How can we construct a system that allows visitors to view our artifact during the day, but invisibly protects it at night in a cost-effective way?"

The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.

The Lost in the Amazon curricular unit is a series of minds-on and hands-on engineering activities based on an adventure scenario set in the Amazon rainforest in Brazil. Students imagine themselves to be a team of EnviroTech engineers returning to the U.S. from a conference in Brasilia, Brazil. When their plane crashes deep in the Amazon forest, they work in groups to overcome various obstacles in their quest to survive and reach the nearest city as quickly and safely as possible. Motivated by this adventurous theme, students discover, learn and apply the following: 1) classification of plants and insects; 2) general categorizing skills; 3) process skills: problem solving and critical thinking; 4) scientific testing and experimentation; 5) materials properties.

Students are given an engineering challenge: A nearby hospital has just installed a new magnetic resonance imaging facility that has the capacity to make 3D images of the brain and other body parts by exposing patients to a strong magnetic field. The hospital wishes for its entire staff to have a clear understanding of the risks involved in working near a strong magnetic field and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks, the physics behind those risks, and the safety precautions to be taken by all staff members. This 10-lesson/4-activity unit was designed to provide hands-on activities to teach end-of-year electricity and magnetism topics to a first-year accelerated or AP physics class. Students learn about and then apply the following science concepts to solve the challenge: magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's law and Faraday's law. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.

Students will breed fruit flies through several generations and record their data using mathematical models in order to demonstrate the inheritance of trait variations.

Through two lessons and four activities, students learn about nanotechnology, its extreme smallness, and its vast and growing applications in our world. Embedded within the unit is a broader introduction to the field of material science and engineering and its vital role in nanotechnology advancement. Engaging mini-lab activities on ferrofluids, quantum dots and gold nanoparticles introduce students to specific fields within nanoscience and help them understand key concepts as the basis for thinking about engineering and everyday applications that use next-generation technology nanotechnology.

Through this unit, students act as engineers who are given the challenge to design laparoscopic surgical tools. After learning about human anatomy and physiology of the abdominopelvic cavity, especially as it applies to laparoscopic surgery, students learn about the mechanics of elastic solids, which is the most basic level of material behavior. Then, they explore the world of fluids and learn how fluids react to forces. Next, they combine their understanding of the mechanics of solids and fluids to understand viscoelastic materials, such as those found in the human body. Finally, they learn about tissue mechanics, including how collagen, elastin and proteoglycans give body tissues their unique characteristics. In the culminating hands-on activity, student teams design their own prototypes of laparoscopic surgical robots remotely controlled, camera-toting devices that must fit through small incisions, inspect organs and tissue for disease, obtain biopsies, and monitor via ongoing wireless image-taking. They use a (homemade) synthetic abdominal cavity simulator to test and iterate the prototype devices.

OpenStax business education resources are specifically designed to appeal to all levels of business interest, exposing students to the core concepts of business in familiar ways to build a strong foundation that can be applied across business fields. Thoughtfully designed examples are presented throughout each chapter, allowing students to build on emerging knowledge. Concepts are further reinforced through applicable connections to more detailed processes. Students are immersed in the "why" as well as the "how" aspects in order to reinforce concepts and promote comprehension over rote memorization.
