The Constitution grants Congress—our nation’s legislative branch—the power to make laws. The legislative branch is outlined in Article I of the Constitution. The Constitution divides Congress into two houses—the U.S. House of Representatives and the U.S. Senate. The House of Representatives is composed of representatives proportionate to each state’s population. At the same time, the Senate is organized under the principle of equal state representation—with each state, regardless of its population, receiving two Senators. In this module, students will examine primary and secondary sources to learn about the legislative branch’s structure, functions, and powers as granted by the Constitution and defined by the courts over time. Students will also explore the legislative process and the role that civil dialogue and political compromise play in crafting national laws.
