Students learn about the wonderful and fascinating country of China, and its environmental challenges that require engineering solutions, many in the form of increased energy efficiency, the incorporation of renewable energy, and new engineering developments for urban and rural areas. China is fast becoming an extremely influential factor in our world today, and will likely have a large role in shaping the decades ahead. China is the world's largest energy consumer and the largest producer of carbon dioxide emissions, leading engineers and scientists to be concerned about the role these emissions play in rural and urban public and environmental health, as well as in global climate change. Through exploring some sources of air pollution, appropriate housing for different climate zones, and the types of renewable energy, the lessons and activities of this unit present ways that engineers are helping people in China, using an approach to cleaner, smarter, healthier and more-efficient ways of living that apply to people wherever they live.

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental engineering, students learn more about water chemistry aspects of environmental engineering. Specifically, they focus on groundwater contamination and remediation, including sources of contamination, adverse health effects of contaminated drinking water, and current and new remediation techniques. Several lab activities provide hands-on experiences with topics relevant to environmental engineering concerns and technologies, including removal efficiencies of activated carbon in water filtration, measuring pH, chromatography as a physical separation method, density and miscibility.

Students explore the methods engineers have devised for harnessing sunlight to generate power. First, they investigate heat transfer and heat storage through the construction, testing and use of a solar oven. With a lesson focused on photovoltaic cells, students learn the concepts of energy conversion, conservation of energy, current and voltage. By constructing model solar powered cars, students see these conceptual ideas manifested in modern technology. Furthermore, the solar car project provides opportunities to explore a number of other topics, such as gear ratios and simple mechanics. Both of these design and construction projects are examples of engineering design.

Studying the Fibonacci Sequence is our entry point for studying Heredity: Inheritance and variation of traits.

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

Students are introduced to the important concept of density with a focus is on the more easily understood densities of solids. Students use different methods to determine the densities of solid objects, including water displacement to determine volumes of irregularly-shaped objects. By comparing densities of various solids to the density of water, and by considering the behavior of different solids when placed in water, students conclude that ordinarily, objects with densities greater than water sink, while those with densities less than water float. Then they explore the principle of buoyancy, and through further experimentation arrive at Archimedes' principle that a floating object displaces a mass of water equal to its own mass. Students may be surprised to discover that a floating object displaces more water than a sinking object of the same volume.

Through a series of three lessons, each with its own hands-on activity, students are introduced to 1) forces, loads and stress, 2) tensile loads and failure, and 3) torsion on structures—fundamental physics concepts that are critical to understanding the built world. The associated activities engage students through experimenting with hot glue gun sticks to experience tension, compression and torsion; the design of plastic chair webbing strips; and problem-solving to reinforce foam insulation "antenna towers" to withstand specified bending and twisting.

From the earliest days of settlement and migration, the people of North America have relied on maps and mapping to understand their environment and place within it. Maps have helped Americans prospect investments, comprehend war, and plan leisure in places unknown. As Americans have used maps to explore the U.S., capitalize on its resources, and displace its Native peoples, maps have shaped American cultural ideas about travel, place, and ownership. This exhibit explores the cultural and historic impact of mapping through four specific moments in American history: migration along the Oregon Trail, the rise of the lumber industry, the Civil War, and the popularization of the automobile and individual tourism. It concludes with a look at maps in the age of computers, the Internet, and beyond. These moments demonstrate the influence maps have had over how Americans imagine, exploit, and interact with national geographies and local places. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students in Professor Helene Williams's capstone course at the Information School at the University of Washington: Greg Bem, Kili Bergau, Emily Felt, and Jessica Blanchard. Additional revisions and selections made by Greg Bem.

Three years before the United States entered World War II, President Roosevelt declared the South to be "the nation's number one economic problem." Georgia's economy was distinctly agricultural and low-wage, with little manufacturing compared with states in the North and Midwest. The median family income was nearly half of the national average. One year later, an influx of federal defense money established new industries, such as the Bell Aircraft plant in Marietta, and expanded existing ones, such as the J. A. Jones Construction Company in Brunswick. While 320,000 Georgians served in the United States Armed Forces, tens of thousands of Georgians repaired aircraft, built B-29 bombers, and worked in shipyards at home during the war. Meanwhile, military training was widespread throughout Georgia, occupying its fields as well as skies. Capitalizing on the state's flat coastal region and mild winters, Army airfields were installed in Savannah, Statesboro, Thomasville, and Waycross, and pilots trained in Albany, Augusta, Americus, and Douglas. Thousands of soldiers passed through Fort Benning and Fort Oglethorpe, where members of the Women's Army Corps trained for positions at home and abroad. World War II employment was crucial to the economic development of the state, ushering in the transformation to a modern, industrial, and diverse Georgia. This exhibition was created as part of the DPLA's Public Library Partnerships Project by collaborators from the Digital Library of Georgia and Georgia's public libraries. Exhibition organizers: Mandy Mastrovita and Greer Martin.

This eight-week module focuses on a “science and society” topic, engaging students in reading compelling informational text about adolescent brain development and the effects of entertainment screen time on the brain.

In Unit 1, students first read various texts that will build their background knowledge about adolescent brain development in general. Their learning will center around three areas of the brain, namely the prefrontal cortex, the limbic system, and the developing neurons. Students determine main ideas and evidence in diverse media and clarify their learning about this complex content. Then they begin to focus on the issue of screen time and how it may affect teenagers.

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.

Located in Washington, Connecticut, the Institute for American Indian Studies (IAIS) was incorporated in 1975. Our focus includes education in conjunction with research. Today, in addition to special events and workshops, IAIS also houses a knowledgeable Education Department dedicated to developing and providing in-depth and exciting programs for students of all ages. Schools throughout the region take advantage of the Institute’s on-site facilities, while schools from across the country contact IAIS for reliable and accurate information. More than 4,000 people visit us each year, and another 7,000 students participate in our education programs.

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!
