I use this in AP Government but if you go over the Commerce Clause thoroughly in regular Government, they are capable of this work as well. There is a title page with a check sheet of what students need to complete. There is a short description and history of the Clause and then students use that info to make a timeline. A list of situations that Congress wants to enact a new law. Students use the Commerce Clause to decide if Congress has the power to make that new law. Included are 12 Supreme Court case descriptions relating to the Commerce Clause. I have students write an opinion on the cases. I assign this as weekend homework.
