In this activity students read three letters written by African-American soldiers during the Civil War to determine why black soldiers felt compelled to join the Union Army.

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.

Students learn about material balances, a fundamental concept of chemical engineering. They use stoichiometry to predict the mass of carbon dioxide that escapes after reacting measured quantities of sodium bicarbonate with dilute acetic acid. Students then produce the reactions of the chemicals in a small reactor made from a plastic water bottle and balloon.

This collection uses primary sources to explore Incidents in the Life of a Slave Girl by Harriet Jacobs. 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.

For the first time in history, the number of world citizens without access to electricity services has dropped below one billion, but still more than 2.8 billion people lack access to clean and affordable cooking fuels. Access to clean, affordable and reliable energy services for all world citizens is a precondition for the achievement of many other Sustainable Development Goals, such as health and economic development.

The provision of sustainable energy services for all is not just a technological challenge or one confined to developing countries. Industrial and post-industrial societies also need to address issues of energy poverty and energy injustice.

Rather than tackling the technological dimension of the formidable challenge to provide an inclusive energy system with renewable and climate-neutral energy resources, this course will focus on its social and institutional dimension. Introduction to the principle of the 4 As of energy services – Accessibility, Availability, Affordability, and Acceptability (environmental and social) will enrich your perspective as an engineering professional. Balancing these four critical and interdependent criteria is a recurrent challenge for individuals and society as a whole, as the characterization of the four As evolves with economic development and changing societal preferences.

You will learn how the rules of the game as defined in laws, regulation and market designs impact the balance between the 4As. Using a wider socio-technical systems perspective you will discover new solutions for the inclusive provision of energy services beyond the purely technological solutions.

After this course you can engage in a richer, more informed debate about how to achieve an inclusive energy system. You will be able to translate this knowledge into strategies to serve society’s future energy needs. The cases presented from developed and developing countries will help you to develop and test your analytical skills. Interviews with industry leaders shaping the energy system will challenge you to reflect on the position these leaders take and the interests they serve.

Lastly, you will put yourself to the test by demonstrating your newly acquired knowledge and skills as a strategic policy advisor, in writing guidelines for a strategic action plan for the energy system and institutional context which are relevant for you, in your company, your city or your country.

Students are asked to consider the expression that arises in physics as the combined resistance of two resistors in parallel. However, the context is not explicitly considered here. The task is good general preparation for problems more specifically aligned to either A-SSE.1 or A-SSE.2.

The purpose of this task is to help students see manipulation of expressions as an activity undertaken for a purpose.

Develops basic concepts for understanding individual, group, and organizational behavior through critical analysis of important works in the field. Areas covered: cognitive psychology, behavioral decision-making, group process and performance, and organizational culture and adaptation. Emphasizes use of behavioral science concepts for stimulating new and useful behavioral science research. Primarily for doctoral candidates in the Sloan School of Management.

Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet, and a second, current carrying coil. Students connect the coil to a circuit and the current from the induced EMF charges a conductor.

How shall we judge the contributions to American society of the great financiers and industrialists at the end of the nineteenth and beginning of the twentieth centuries? In this lesson, students explore a variety of primary historical sources to uncover some of the less honorable deeds as well as the shrewd business moves and highly charitable acts of the great industrialists and financiers, men such as Andrew Carnegie, J. Pierpont Morgan, John D. Rockefeller, and Cornelius Vanderbilt.

As fossil-based fuels and raw materials contribute to climate change, the use of renewable materials and energy as an alternative is increasingly important and common. This transition is not a luxury, but rather a necessity. We can use the unique properties of microorganisms to convert organic waste streams into biomaterials, chemicals and biofuels.

This course provides the insights and tools for the design of biotechnology processes in a sustainable way. Five experienced course leaders will teach you the basics of industrial biotechnology and how to apply these to the design of fermentation processes for the production of fuels, chemicals and foodstuffs.

Throughout this course, you will be challenged to design your own biotechnological process and evaluate its performance and sustainability. This undergraduate course includes guest lectures from industry as well as from the University of Campinas in Brazil, with over 40 years of experience in bio-ethanol production. The course is a joint initiative of TU Delft, the international BE-Basic consortium and University of Campinas.

Covers theoretical and empirical work dealing with the structure, behavior, and performance of firms and markets and core issues in antitrust. Topics include: the organization of the firm, monopoly, price discrimination, oligopoly, and auctions. Theoretical and empirical work are integrated in each area.

This short video and interactive assessment activity is designed to teach third graders about inequalities.

This short video and interactive assessment activity is designed to teach fifth graders about inequalities with addition and subtraction of fractions.

This course is an introduction to cognitive development focusing on children's understanding of objects, agents, and causality. It develops a critical understanding of experimental design. The course discusses how developmental research might address philosophical questions about the origins of knowledge, appearance and reality, and the problem of other minds. It provides instruction and practice in written communication as needed for cognitive science research (including critical reviews of journal papers, a literature review and an original research proposal), as well as instruction and practice in oral communication in the form of a poster presentation of a journal paper.

Fundamental methods used for exploring the information content of observations related to kinematical and dynamical models. Basic statistics and linear algebra for inverse methods including singular value decompositions, control theory, sequential estimation (Kalman filters and smoothing algorithms), adjoint/Pontryagin principle methods, model testing, etc. Second part focuses on stationary processes, including Fourier methods, z-transforms, sampling theorems, spectra including multi-taper methods, coherences, filtering, etc. Directed at the quantitative combinations of models, with realistic, i.e. sparse and noisy observations.

Inferring and Explaining is a book in practical epistemology. It examines the notion of evidence and assumes that good evidence is the essence of rational thinking. Evidence is the cornerstone of the natural, social, and behavioral sciences. But it is equally central to almost all academic pursuits and, perhaps most importantly, to the basic need to live an intelligent and reflective life.

Much of statistics is based upon using data from a random sample that is representative of the population at large. From that sample mean, we can infer things about the greater population mean. We'll explain.
