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).

Now you can start scaling your shapes to make your lamp look younger.

Now you are ready to start subdividing your own shapes with more than 4 points!

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 women could have their own businesses, own and sell property, and serve as witnesses in court cases. Unlike most women in the Middle East, they were even permitted to be in the company of men. They could escape bad marriages by divorcing and remarrying. And women were entitled to one third of the property their husbands owned. The political and economic rights Egyptian women enjoyed made them the most liberated females of their time.

This unit on American Indians: By studying the regions of the United States and the cultures that live in each region, students are able to compare/contrast within regions and across regions how tribes used their environments, and their cultural and other contributions to American life.

Note that the emphasis here is on broader groups of tribes for each region with some instruction on specific tribes representing each region. In no way is this case study approach to learning about one tribe meant to be generalized to all tribes of that region. We understand that each tribe was and continues to be unique in its culture, practices, lifeways, and traditions.
