The Declaration of Independence and the words “all men are created equal” provided thousands of enslaved Africans high expectations and many were ready to fight for the Country and their own personal freedom. Thousands of enslaved Africans impacted the war right from the start at Lexington and Concord, all the way to the end at Yorktown. This lesson will explore the life of James Armistead Lafayette, an enslaved African Virginian. Working as an undercover spy for George Washington, James risked his life to gather key intelligence about the British that helped secure an American victory at Yorktown. In this lesson, we will discuss whether his efforts in service of the American cause helped or hindered his ability to achieve emancipation.

Before the 13th Amendment officially ended slavery in the United States, free and enslaved African Americans fought for their liberty, society’s recognition of their humanity, and the promise of equality. A variety of methods were used by enslaved African Americans to resist the conditions they experienced while in bondage. In this lesson plan, students will learn about three individuals whose actions are a representation of the bravery of African Americans who fought for their freedom and equality. 

Authors: John Marshall Center for Constitutional History & CivicsSarah Waltman King, Richmond Public Schools In 1865, the ratification of the 13th Amendment officially ended slavery in the United States. After fighting for their liberty before and during the Civil War, enslaved African Americans saw their dreams of emancipation realized. In the years that followed the end of the war, Virginia and other southern states had to reconfigure their social, economic, and political systems during a period called Reconstruction. During this era, newly freed Black Virginians experienced advancements but also encountered barriers to achieving true equality. This lesson explores  whether African Americans truly “free” following the passage of the 13th Amendment.Key Hook/QuestionWere African Americans truly free following the passage of the 13th Amendment?

John Marshall Center for Constitutional History & CivicsSarah Waltman King, Richmond Public Schools Throughout the four centuries of history covered in Determined, access to education was at the heart of the African American struggle for equality. While slavery was legal, enslaved Americans were prohibited by law from being taught to read and write, and had no access to formal education. Following emancipation and the 13th Amendment, Black Americans temporarily enjoyed increased access to education, but those rights quickly evaporated under new Jim Crow laws. Under those provisions, Virginia and other southern states established “separate but equal” schools that segregated students by race, which resulted in unequal conditions for Black and White children. Despite these setbacks, African Americans continued to aggressively pursue their right to an education.What academic challenges and successes did Mary S. Peake and Barbara Johns experience throughout their lives?

Genetics, otherwise known as the Science of Heredity, is the study of biological information, and how this information is stored, replicated, transmitted and used by subsequent generations. The study of genetics can be sub-divided into three main areas: Transmission Genetics, Molecular Genetics, and Population Genetics. In this Introductory text, the focus is on Transmission or Classical Genetics, which deals with the basic principles of heredity and the mechanisms by which traits are passed from one generation to the next. The work of Gregor Mendel is central to Transmission Genetics; as such, there is a discussion about the pioneering work performed by him along with Mendel’s Laws, as they pertain to inheritance. Other aspects of Classical Genetics are covered, including the relationship between chromosomes and heredity, the arrangement of genes on chromosomes, and the physical mapping of genes.
