Hi!  I just wanted to share that the federalism yarn activity was an excellent activity to give the students a more concrete example of what is federalism.  To get the students in a circle and get a string of yarn and state what applies in the federal, state, and even the local level, and pass it around, you can see how federalism relates to each level.  Questions can be posed by the teacher in relation to what can happen to the yarn when each level is affected, such as "What happens when the states are in conflict with the federal law?" and they tug at it.  The tension that is given is the tension that states feel against the federal law.  Great example! I am wondering if this resource will be posted online in this website?  And what other questions can I ask the students in this activity?
