The National Humanities Center presents collections of primary resources compatible with the Common Core State Standards - historical documents, literary texts, and works of art - thematically organized with notes and discussion questions. Topics discussed in this unit include the following: Becoming Modern: America in the 1920s: Labor Strike. Studying the broad reaction to labor strikes in the early 1920s requires a broad selection of genres - here we consider newspaper coverage of a specific strike, a novelist's portrayal of a strike's polarizing effects, and two cartoon animators' humorous takes on "the strike."

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Explain fetal development during the three trimesters of gestation
Describe labor and delivery
Compare the efficacy and duration of various types of contraception
Discuss causes of infertility and the therapeutic options available

The Lawrence Textile Strike was a public protest mainly of immigrant workers from several countries, including Austria, Belgium, Cuba, Canada, France, England, Germany, Greece, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Russia, Scotland, Spain, Syria, and Turkey. According to the 1910 census, 65% of mill workers (many of whom eventually struck) lived in the United States for less than 10 years; 47% for less than five years. Prompted by a wage cut, the walkout spread quickly from mill to mill across the city. Strikers defied the assumptions of conservative trade unions within the American Federation of Labor that immigrant, largely female and ethnically diverse workers could not be organized. The Lawrence strike is referred to as the åÒBread and RosesåÓ strike and åÒThe Strike for Three Loaves." The first known source to do so was a 1916 labor anthology, The Cry for Justice: An Anthology of the Literature of Social Protest by Upton Sinclair. Prior to that, the slogan, used as the title of a 1911 poem by James Oppenheim, had been attributed to åÔChicago Women Trade Unionists.åÕ It has also been attributed to socialist union organizer Rose Schneiderman. James Oppenheim claimed his seeing women strikers in Lawrence carrying a banner proclaiming åÒWe Want Bread and Roses TooåÓ inspired the poem, åÒBread and Roses.åÓ The poem, however, was written and published in 1911 prior to the strike. Later the poem was set to music by Caroline Kohlsaat and then by Mimi Farina. The song and slogan are now important parts of the labor movement and womenåÕs movement worldwide. This exhibition was made in collaboration with the Lawrence History Center and the University of Massachusetts Lowell History Department.

This video teaches the concept of Productive Resources. Productive resources are used to produce goods and services and are classified into four categories: land, labor, capital, and entrepreneurship.[1:32]

In dieser Simulation wird die Gelelektrophorese eingeführt, eine Methode

In dieser Simulation können Teilnehmer die Verwendung einer Mikropipette in einer virtuellen Laborumgebung üben. Zu den in dieser Simulation im Vordergrund stehenden Fähigkeiten gehören die Dispensierung verschiedener Flüssigkeitsvolumen mit einer P20-Mikropipette und die Verwendung des ersten und zweiten Anschlags.

This collection uses primary sources to explore the Bracero Program. 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.

Amidst tensions over European political and territorial boundaries, the assassination of Archduke Franz Ferdinand by a Serbian terrorist in 1914 derailed peace in the western world by sparking World War IåÑone of the highest-casualty conflicts in modern times. While European nations quickly engaged, the United States immediately declared neutrality. By 1917, however, remaining neutral was no longer an option. The Great War would bring the United States out of isolationism and onto the world stage. It would also change life on the American home front forever. A centralized government took control of American life in an unprecedented fashion by instating a mandatory military draft, controlling industries, initiating food and ration restrictions, and launching elaborate campaigns to encourage patriotism. One of the most important, if temporary, changes brought by the war at home came from the stifled flow of labor, as men were pulled away by the draft and immigration slowed. The need for American labor provided second-class citizens, such as women and African Americans, a brief opportunity for better jobs. This glimpse would help foment in them a desire for more and equal opportunities after they were pulled away once more at waråÕs end. This exhibition was created as part of the DPLAåÕs Public Library Partnerships Project by collaborators from Digital Commonwealth. Exhibition organizer: Anna Fahey-Flynn.

Students learn about the major factors that comprise the design and construction cost of a modern bridge. Before a bridge design is completed, engineers provide overall cost estimates for construction of the bridge. Students learn about the components that go into estimating the total cost, including expenses for site investigation, design, materials, equipment, labor and construction oversight, as well as the trade-off between a design and its cost.

While learning about the California migrant farm workers' fight for justice led by Cesar Chavez and Dolores Huerta, students learn to make connections and think about cause and effect.

The Unladylike2020 Collection honors the centennial of women's suffrage. These digital resources present the rich history of 26 little-known Progressive Era women, diverse in profession, race, ethnicity, geographical and class backgrounds, sexual orientation and gender expression, who broke barriers in then-male-dominated fields. Touching on topics such as the labor movement, immigration, politics, civil rights, and women's suffrage, these resources develop students' historical thinking skills and help them make connections between past and present. In This Collection: Video (70), Media Gallery (2), Webpage (2), Interactive Lesson (7), Interactive (7) for Grades 6-8, 9-12

Students discuss several human reproductive technologies available today pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.

In reading and discussing Lyddie, by Katherine Paterson, students examine basic economic concepts and explore the growth of labor unions and the role of government in a market economy.

This collection uses primary sources to explore women's work on the home front during World War II. 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.

Student teams learn about and devise technical presentations on four reproductive technology topics pregnancy ultrasound, amniocentesis, in-vitro fertilization or labor anesthetics. Each team acts as a panel of engineers asked to make a presentation to a group of students unfamiliar with the reproductive technology. Each group incorporates non-lecture elements into its presentation for greater effectiveness. As students learn about the technologies, by creating a presentation and listening to other groups' presentations, they also learn more about the valuable skill of technical communications.
