This OER explores the basic organization of the Pythagorean Solids. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

Virginia was the first successful southern colony. While Puritan zeal was fueling New England's mercantile development, and Penn's Quaker experiment was turning the middle colonies into America's bread basket, the South was turning to cash crops. Geography and motive rendered the development of these colonies distinct from those that lay to the North.

New England was not the only destination sought by those fleeing religious persecution. In 1632, Cecelius Calvert, known as Lord Baltimore, was granted possession of all land lying between the Potomac River and the Chesapeake Bay. Lord Baltimore saw this as an opportunity to grant religious freedom to the Catholics who remained in Anglican England. Although outright violence was more a part of the 1500s than the 1600s, Catholics were still a persecuted minority in the seventeenth century. For example, Catholics were not even permitted to be legally married by a Catholic priest. Baltimore thought that his New World possession could serve as a refuge. At the same time, he hoped to turn a financial profit from the venture.

Greece's mountainous terrain led to the development of the polis (city-state), beginning about 750 B.C.E. The high mountains made it very difficult for people to travel or communicate. Therefore, each polis developed independently and, often, very differently from one another. Eventually, the polis became the structure by which people organized themselves. Athens and Sparta are two good examples of city-states that contrasted greatly with each other.

In Athenian democracy, every citizen was required to participate or suffer punishment. This practice stands in stark contrast to modern democratic governments in which citizens can choose whether or not they wish to participate. In Athenian democracy, all citizens pulled their weight.

The growth of tobacco, rice, and indigo and the plantation economy created a tremendous need for labor in Southern English America. Without the aid of modern machinery, human sweat and blood was necessary for the planting, cultivation, and harvesting of these cash crops. While slaves existed in the English colonies throughout the 1600s, indentured servitude was the method of choice employed by many planters before the 1680s. This system provided incentives for both the master and servant to increase the working population of the Chesapeake colonies.

While wayward English migrants worked to build the new American colonies, mother England experienced the greatest turmoil in her history in the middle of the 1600s. The Stuart King, Charles I, was beheaded as the result of a civil war in 1649. A dictatorship led by Oliver Cromwell ruled England until 1660. This represented the only break in the hereditary line dating from 1066 until the present day. Cromwell was a brutal leader, so the return of the English monarchy was well received by the public. This disruption caused a temporary distraction from colonizing the New World. When Charles II assumed the throne, it was business as usual. The colonies that were created under his rule were known as Restoration colonies. It was in this environment that the Carolinas were created.

The development of Georgia was unlike all the other British colonies. First of all, it was the last to be created. Georgia was founded in 1733, 126 years after Jamestown was successfully planted. England and Europe as a whole were in the midst of an intellectual revolution known as the Enlightenment. Enlightened thinkers championed the causes of liberty and progress. Many believed in the innate goodness of human beings. They asserted that even the worst elements of society might prosper if given the right set of circumstances. James Oglethorpe was such a thinker. He and a group of charitable investors asked King George for permission to create a utopian experiment for English citizens imprisoned for debt. England's prison population could be decreased, and thousands of individuals could be given a new chance at life. With these lofty goals, Georgia was created.

Greek dramas typically dealt with important issues of the day, posed tough questions, and educated theatergoers. Attendance at dramas was considered such a valuable experience that sometimes the government would pay for the tickets.

The arts reflect the society that creates them. Nowhere is this truer than in the case of the ancient Greeks. Through their temples, sculpture, and pottery, the Greeks incorporated a fundamental principle of their culture: arete. To the Greeks, arete meant excellence and reaching one's full potential.

Plantation life created a society with clear class divisions. A lucky few were at the top, with land holdings as far as the eyes could see. Most Southerners did not experience this degree of wealth. The contrast between rich and poor was greater in the South than in the other English colonies, because of the labor system necessary for its survival. Most Southerners were yeoman farmers, indentured servants, or slaves. The plantation system also created changes for women and family structures as well.

2,500 years ago, most humans were concerned with providing food and protection for their families and little else. Most of them were ruled by kings or pharaohs who had supreme decision-making power. The Athenian democracy encouraged countless innovative thoughts among its citizens.
