Lights, trolleys, skyscrapers, romance, action. These were among the first words to enter the minds of Americans when contemplating the new urban lifestyle. While American cities allowed many middle- and upper-class Americans to live a glamorous lifestyle, this was simply a fantasy to many poorer urban dwellers. Slums, crime, overcrowding, pollution, disease. These words more accurately described daily realities for millions of urban Americans.

Immigration was nothing new to America. Except for Native Americans, all United States citizens can claim some immigrant experience, whether during prosperity or despair, brought by force or by choice. However, immigration to the United States reached its peak from 1880-1920. The so-called "old immigration" brought thousands of Irish and German people to the New World.

To cope with the city's problems, government officials had a limited resources and personnel. Democracy did not flourish in this environment. To bring order out of the chaos of the nation's cities, many political bosses emerged who did not shrink from corrupt deals if they could increase their power bases. The people and institutions the bosses controlled were called the political machine.

Many historians call this period in the history of American religion the Third Great Awakening. Like the first two awakenings, it was characterized by revival and reform. The temperance movement and the settlement house movement were both affected by church activism. The chief difference between this movement and those of an earlier era was location. These changes in religion transpired because of urban realities, underscoring the social impact of the new American city.

Like the American economy, American art and literature flourished during the Gilded Age. The new millionaires desired greatly to furnish their mansions with beautiful things. Consequently, patronage for the American arts was at a higher level than any previous era. Painters depicted a realistic look at the glories and hardships of this new age. Writers used their pens to illustrate life at its best and its worst. The net result was an American Renaissance of arts and letters.

City life or country life? The typical farmer rose with the sun, tended the animals, worked the fields, broke bread with the family, and retired when the sun went down. With the exceptions of the Sabbath and holiday observances, life remained constant, changing only with the seasons. While this bucolic lifestyle was and still is romanticized by many, it simply bore no resemblance to big city existence. The city promised conveniences, nightlife, excitement and variety.

Demands for better public education were many. Employers wanted a better educated workforce, at least for the technical jobs. Classical liberals believed that public education was the cornerstone of any democracy. Our system of government could be imperiled if large numbers of uneducated masses voted unwisely.

A sports craze was sweeping the nation. Work weeks were still long, averaging about sixty hours per week in 1890. But the average worker notched 66 hours in 1860, giving the typical American six extra hours of free time each week. Three more decades would see an additional 10 hours of average working time turn into free time.

The idea was to create a maternal commonwealth. Upper-middle-class women of the late 19th century were not content with the cult of domesticity of the early 1800s. Many had become college educated and yearned to put their knowledge and skills to work for the public good.

Victorian values dominated American social life for much of the 19th century. The notion of separate spheres of life for men and women was commonplace. The male sphere included wage work and politics, while the female sphere involved childrearing and domestic work.

Even the news was a business. As Americans streamed into cities from small towns and overseas, journalists realized the economic potential. If half of Boston's citizens would buy a newspaper three times a week, a publisher could become a millionaire.

Students learn how 3D printing, also known as additive manufacturing, is revolutionizing the manufacturing process. First, students learn what considerations to make in the engineering design process to print an object with quality and to scale. Students learn the basic principles of how a computer-aided design (CAD) model is converted to a series of data points then turned into a program that operates the 3D printer. The activity takes students through a step-by-step process on how a computer can control a manufacturing process through defined data points. Within this activity, students also learn how to program using basic G-code to create a wireframe 3D shapes that can be read by a 3D printer or computer numerical control (CNC) machine.

In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).

The founders of the New England colonies had an entirely different mission from the Jamestown settlers. Although economic prosperity was still a goal of the New England settlers, their true goal was spiritual. Fed up with the ceremonial Church of England, Pilgrims and Puritans sought to recreate society in the manner they believed God truly intended it to be designed.

The first group to leave England actually headed for the Dutch Netherlands in 1608. They became uneasy in their new land as their children started speaking Dutch and abandoning English traditions. Even worse to the Separatists, the tolerance shown to them by the Dutch was shown to many different faiths. They became disgusted with the attention paid to worldly goods, and the presence of many "unholy" faiths. The great Separatist experiment in the Netherlands came to a quick end, as they began to look elsewhere for a purer place to build their society. Some headed for English islands in the Caribbean. Those who would be forever known to future Americans as the Pilgrims set their sights on the New World in late 1620.

The passengers of the Arbella who left England in 1630 with their new charter had a great vision. They were to be an example for the rest of the world in rightful living. Future governor John Winthrop stated their purpose quite clearly: "We shall be as a city upon a hill, the eyes of all people are upon us."

New England life seemed to burst with possibilities. The life expectancy of its citizens became longer than that of Old England, and much longer than the Southern English colonies. Children were born at nearly twice the rate in Maryland and Virginia. It is often said that New England invented grandparents, for it was here that people in great numbers first grew old enough to see their children bear children.

There was not too much room for religious disagreement in the Massachusetts Bay Colony. Puritans defended their dogma with uncommon fury. Their devotion to principle was God's work; to ignore God's work was unfathomable. When free-thinkers speak their minds in such a society, conflict inevitably results.

Despite a few internal problems, Massachusetts Bay Colony was thriving by the mid-1630s. It would only be a matter of time before individuals within the colony would consider expansion.

Surely the Devil had come to Salem in 1692. Young girls screaming and barking like a dog? Strange dances in the woods? This was behavior hardly becoming of virtuous teenage maidens. The town doctor was called onto the scene. After a thorough examination, he concluded quite simply — the girls were bewitched. Now the task was clear. Whomever was responsible for this outrage must be brought to justice.
