Powerful kingdoms, beautiful sculpture, complex trade, tremendous wealth, centers for advanced learning — all are hallmarks of African civilization on the eve of the age of exploration. Hardly living up to the "dark continent" label given by European adventurers, Africa's cultural heritage runs deep. The empires of Ghana, Mali, and Songhay are some of the greatest the world has ever known. Timbuktu, arguably the world's oldest university, was the intellectual center of its age.

Some will die of disease, some of starvation, and some simply of despair. This was the fate of millions of West Africans across three and a half centuries of the slave trade on the voyage known as the "middle passage."

Africans were the immigrants to the British New World that had no choice in their destinations or destinies. The first African Americans that arrived in Jamestown in 1619 on a Dutch trading ship were not slaves, nor were they free. They served time as indentured servants until their obligations were complete. Although these lucky individuals lived out the remainder of their lives as free men, the passing decades would make this a rarity. Despite the complete lack of a slave tradition in mother England, slavery gradually replaced indentured servitude as the chief means for plantation labor in the Old South.

What was it like to live in bondage? The experiences of slaves in captivity varied greatly. Indeed, Puritan merchants and Southern planters have as much in common as their slaves. The type of life slaves could expect to live depended first and foremost on whether they lived on farms or in towns.

When Crispus Attucks earned his unfortunate claim to fame as a victim in the Boston Massacre, he was not a slave. He was one of the relatively few African Americans to achieve freedom in colonial America. Although freedom is clearly desirable in comparison to a life in chains, free African Americans were unfortunately rarely treated with the same respect of their white counterparts.

Slaves did not accept their fate without protest. Many instances of rebellion were known to Americans, even in colonial times. These rebellions were not confined to the South. In fact, one of the earliest examples of a slave uprising was in 1712 in Manhattan. As African Americans in the colonies grew greater and greater in number, there was a justifiable paranoia on the part of the white settlers that a violent rebellion could occur in one's own neighborhood. It was this fear of rebellion that led each colony to pass a series of laws restricting slaves' behaviors. The laws were known as slave codes.

When immigrants reach a new land, their old ways die hard. This has been the case with most immigrant groups to the New World. The language, customs, values, religious beliefs, and artistic forms they bring across the Atlantic are reshaped by the new realities of America and, in turn, add to its fabric. The rich traditions of Africa combined with the British colonial experience created a new ethnicity — the African American.

In this part of the unit on ratios and proportions, students will use ratio language to write ratios in a real-world context.  They will be architects who are designing an amusement park, an aquarium research center, or a baseball stadium.  Students will write equivalent ratios and use them to make their building a physically safe space that meets all building requirements.  During this project, students will also be converting between units (e.g., inches and feet) as they find equivalent ratios.  After students have made all of their calculations, they will analyze another set of design specifications and create a presentation explaining whether these new specifications would result in an architecturally safe building.  Students will use their math calculations from the design challenge to justify their answers.

In this part of the unit, students are exploring how global temperatures have changed over the past hundred years.  Students will examine tables and graphs about global temperatures and carbon dioxide levels, human consumption of food, and human consumption of natural resources.  They will find patterns in the graphs.  Based on this data, students will construct an argument about how human activities (increase in population and consumption of natural resources) cause global temperatures to increase.
