Have you ever struggled to get your students engaged while teaching Federalism? This lesson will be sure to engage students in analyzing the Constitution while also making connections to current issues. In this lesson students will first analyze the expressed powers of the Constitution. Then students will apply the Necessary and Proper Clause to implied powers. Last, they will be taken through a historical debate on the extent of the Commerce Power and apply this debate to the very controversial, yet interesting issue of the legalization of marijuana. This lesson will be sure to interest students, and keep students interested until the very end. Plus there is a writing prompt and rubric included. Side note: I like to introduce this lesson with the first 5 minutes of Constitution USA- A More Perfect Union with Peter Sagal.
