Lesson 1: The United States Constitution

Key Idea

After breaking away from England, American leaders wanted to create a government that was strong but not too powerful. They wrote the Constitution as a master plan. This plan created a government with clear limits on its power to protect the people's freedom.

A main idea in this plan is the rule of law. This means that everyone, from a regular citizen to the president, must follow the same laws. The plan also established federalism, a system that shares power between the national government and the state governments.

Key Idea

To prevent any one group from becoming too powerful, the writers of the Constitution divided the government into three branches. This plan, called the separation of powers, splits the government's main jobs into three different parts.

The Legislative Branch (Congress) is in charge of making laws.

Key Idea

The writers of the Constitution wanted to prevent any one part of the government from becoming too powerful, like a king. They remembered what it was like to live under British rule and wanted to ensure fairness and shared power.

To achieve this, they created a system of checks and balances. This system gives each of the three branches special ways to limit, or “check,” the power of the other two. This forces the branches to work together.

Key Idea

In the United States, the job of governing is too big for just one group. This system of sharing power is called federalism. It creates three levels of government: national, state, and local. Each level has its own special jobs to do for the people it serves.

The national government handles big jobs for the whole country, like managing highways that cross from one state to another. State governments, like California's, manage state parks and schools. Your local city or county government handles things close to home, like fixing potholes and running libraries.
