Amendment Process: The method by which changes or additions are made to the Constitution. Like updating an app on your phone with new features or bug fixes.
Federalism: A system where power is divided between national and state governments. Imagine if you shared control over your playlist with your friend - some songs you choose (federal), some songs they choose (state).
Judicial Review: The power of the courts to declare laws unconstitutional. It's like a teacher grading your paper and marking some answers as incorrect.
