Bill of Rights: This is the first ten amendments to the US Constitution that outline specific protections for individual liberties such as freedom of speech, religion, and press.
Federalism: This is a system where power is divided between national (federal) government and state governments. It's like dividing responsibilities between parents (national government) and children (state governments).
Separation of Powers: This principle divides governmental powers into three branches - legislative (makes laws), executive (enforces laws), and judicial (interprets laws). It's like splitting chores among siblings so no one person has all control or responsibility.
