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.

None of the achievements of the remarkable ancient Egyptian civilization would have been possible without the Nile River. There is always a connection between landscape and how a people develop. It does not take the wisdom of a sphinx to understand why.

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.

Egyptian society was structured like a pyramid. At the top were the gods, such as Ra, Osiris, and Isis. Egyptians believed that the gods controlled the universe. Therefore, it was important to keep them happy. They could make the Nile overflow, cause famine, or even bring death.

The major similarity between the first Jamestown settlers and the first Plymouth settlers was great human suffering. November was too late to plant crops. Many settlers died of scurvy and malnutrition during that horrible first winter. Of the 102 original Mayflower passengers, only 44 survived. Again like in Jamestown, the kindness of the local Native Americans saved them from a frosty death.

Ancient Egypt, also had dynasties. They were families who often ruled for a considerable number of years and did impressive things — such as building pyramids — during their rule.

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.
