Health care bill unit study?

In light of the passing of the health care bill, my daughter (18) has been doing her own research. I tagged along. Here are a few topics:

Powers specified to government
the commerce clause
Sixteenth amendment
Social Security
Barack Obama voting record, as well as some other well known politicians
Fourteenth amendment
looked up of our state representative
Tenth amendment
"separation of church and state"-is this fact or fiction?
Thomas Jefferson and his worldview

We decided that it would take years to study the Constitution, as well as these other topics. We also concluded that there is always more desire to study something when it is more relevant to your own life. There is a lot to learn, this is just a start :)
