Phase 02
Day 1: The Three Branches and Their Powers
Hook (10 min): Write on the board: "What stops the President from becoming a king?" Have students turn-and-talk, then share answers. List their ideas on the board and circle any that involve another branch of government.
Mini-Lesson (20 min): Walk through Article I (Congress writes laws, controls money), Article II (President enforces laws, commands military), Article III (Courts interpret laws, judge constitutionality). Use a triangle diagram on the board that students copy into notes. Emphasize the Founders' fear of concentrated power after their experience with King George III.
Student Activity (15 min): Give each group a card with a real power (e.g., "veto a bill", "declare war", "appoint a Supreme Court justice", "reject a treaty"). Students must place the card under the correct branch, then answer: Which branch does this power belong to? Who can check it, and how?
Phase 03
Exit Ticket (10 min): "Which branch do you think has the most power today, and why? Does that match what the Founders intended? Give one example to support your answer."
